Resumen

The mini-cuttings productivity in clonal mini-garden using the semi-hydroponic system is a promising technique for the olive propagation, to obtaining a satisfactory amount of cuttings and with good quality. The objective was to evaluate the mini-stumps productivity and rooting of olive mini-cuttings in successive collections at different times of year in a clonal mini-garden in a semi-hydroponic system. In each collection the productivity of the clonal mini-garden was evaluated counting the collected cuttings. The mini-cuttings were prepared with 3-5 cm long with leaf area reduced by 50% and placed in plastic boxes with vermiculite for a period of 80 days. The evaluated variables were: mini-stumps productivity, mini-stumps and mini-cuttings percentage of survival, rooting percentage and number and length of mini-cuttings root. The olive mini-cuttings presented higher productivity during the spring of 2014. The mini-cuttings rooting percentage collected during the evaluated periods demonstrated that mini-cutting is a viable technique for olive propagation when grown in clonal mini-garden using a semi-hydroponic system.

Resumen

ABSTRACT This study presents an efficient system with high productivity and quality for Acer palmatum propagation. We evaluated the efficiency of mini-cuttings technique, management of mini-stumps, production of shoots, rooting and root vigor of mini-cuttings on two seasons. The mini-stumps were planted in pots of two liters, put up in two environments (full sunlight area and shade house) and submitted to weekly fertigation. Over six collections, we evaluated the survival and productivity of clonal mini-garden (Experiment I). From these, we performed two experiments with mini-cuttings: Experiment II - mini-cuttings originated from two environments, with 8±1 cm, put to root in two seasons (Spring and Summer); Experiment III - mini-cuttings originated from full sunlight area, with 4±1, 6±1, 8±1, 10±1 cm, put to root in Summer. The mini-cuttings planting was made in plastic tubes of 55 cm³, filled with fine vermiculite and carbonized rice hulls (1:1 v/v), in a greenhouse with intermittent irrigation system. The high rooting (95.0%), mini-stumps survival (100%) and mini-cuttings production (217.5 mini-cuttings m-2 month-1) in clonal mini-garden conducted in full sunlight area shown the technique viability for the species. Mini-cuttings of 8±1 cm favored rooting (96.3%). The mini-cuttings technique is viable for Acer palmatum propagation.

Resumen

Abstract: The objective of this work was to define an early selection strategy to identify Cabralea canjerana (Meliaceae) clones with high multiplication rate. A mini-garden of 109 clones of canjerana seedlings was established in a completely randomized design, in an acclimatized greenhouse. From seedlings, the mini-stumps and mini-cuttings were obtained. Mini-cuttings were collected at five different times, and the number of mini-cuttings per mini-stump, rooting percentage, and number of rooted mini-cuttings were quantified. The number of rooted mini-cuttings per mini-stump was the only trait that showed high correlation with the others. Five groups of clones based on the number of rooted mini-cuttings per mini-stump were separated using k-means clustering, and the genetic gain from selection and Pearson correlation were estimated. The selection of the two best groups in each evaluation period resulted in high genetic gains from selection for all evaluated traits. Early selection for the number of rooted mini-cuttings discarded 65% of the evaluated clones, which increases experimental precision in evaluations of traits associated with plantlet growth and quality. Early selection for the number of rooted mini-cuttings per mini-stump at different times allows the identification of Cabralea canjerana clones with high multiplication rate.

Resumen

ABSTRACTWe aimed to evaluate the technical efficiency of mini-cuttings technique on vegetative propagation of Paulownia fortunei (Seem.) Hemsl. var. Mikado, as well as the possible existence of anatomical barriers to its rooting. Therefore, plants originated from cuttings formed the mini-stumps and, consequently the clonal mini-garden, which was conducted in semi-hydroponic system. We evaluated the survival of mini-stumps and sprouts production for five successive collects, the percentage of mini-cuttings rooting and their anatomical description. The mini-cuttings were prepared with about 6 to 8 cm in length and two leaves reduced by about 50% in the upper third, being remained an area of, approximately 78 cm2 (10 cm diameter). The mini-cuttings were placed in tubes of 53 cm3, with substrate formed with fine vermiculite and carbonized rice hulls (1:1 v/v) and rooted in acclimatized greenhouse. After 30 days we evaluated the percentage of rooted mini-cuttings, radicial vigor (number and length of roots / mini-cutting), callus formation, emission of new shoots and maintenance of the original leaves. The mini-stumps showed 100% survival after five collects and an average production of 76-114 mini-cuttings/m2/month and rooting ranged from 70 to 90%. Mini-cuttings technique is efficient in to propagate adult propagules of the species and there are not anatomical barriers preventing roots emission.

Resumen

This study aimed to evaluate the production of cordia (Cordia trichotoma) ministumps of seminal and asexual origin, as well as the effect of the naphthaleneacetic acid (NAA) on the rooting of mini-cutitings. Seedlings and plantlets from rooted cuttings were pruned to form a clonal mini-hedge. The ministumps were fertirrigated with three concentrations of nutrient solution and they were evaluated for survival and production of mini-cuttings. The mini-cuttings were or not treated with 1000mg L-1 of NAA and planted in substrate for rooting. The mini-cuttings were evaluated for the percentages of survival and rooting, and number and total length of roots after 30 days of cultivation. There was no difference in survival and number of mini-cuttings obtained from seminal or asexual ministumps. Mini-cuttings from ministumps of asexual origin showed higher rooting capability. The use of 1000mg L-1 NAA did not increase the rooting percentage of cordia mini-cuttings.

Resumen

With the need of a large-scale seedling production, the application of purple nutsedge extract may represent a promising alternative, contributing to the fruit species propagation. The aim of this study was to evaluate the effects of nutsedge extract on the survival rate, rooting and biomass of acerola’s mini-cuttings. The experimental design was a completely randomized block, with a 5x2 factorial arrangement (five aqueous purple nutsedge extracts of nutsedge (0%, 25%, 50%, 75% and 100%) and two types of mini-cuttings, a pair of entire leaves and a pair of half leaves) resulting in 10 treatments with 5 repetitions and 8 mini-cuttings per repetition. The evaluations were performed at 75 days after planting, when destructive analysis were carried out for morphological characteristics. The evaluates variables were mini-cuttings survival percentage, percentage of mini-cuttings with sprouts, percentage of mini-cuttings with callus, percentage of minicuttings with roots, root system length, shoot dry mass, root dry mass, total dry biomass and the ratio between shoot and root dry mass. For the experiment conditions, the nutsedge extract positively influenced the survival percentage and percentage of sprouting of acerola’s mini-cuttings, however the extract application did not influence the mini-cuttings biomass of, being the results observed with or without the cut on mini-cuttings leaves.

Resumen

Drimys brasiliensis, popularly known as cataia or casca-d'anta, is a tree species native to the Atlantic Forest and belonging to the family Winteraceae. Due to its seeds have dormancy due to embryonic immaturity, the present work aimed to evaluate the viability of the mini-cutting technique in D. brasiliensis in different seasons of collection of the propagules. Mini-cuttings from seedlings sprouts previously produced by conventional cutting were collected at six different times (December/2015, February/2016, April/2016, June/2016, August/2016 and October/2016), made 6-8 cm long, with bevel cut at the base and rectum at the apex, keeping two leaves with their area halved. The experiment was carried out in a completely randomized design with 4 replicates and 14 mini-cuttings per experimental unit. The mini-cuttings were planted in tubes with substrate containing vermiculite and carbonized rice husk (1:1) and kept in a heated greenhouse. After 120 days, the percentage of rooted mini-cuttings, number of roots per mini-cuttings, length of the three largest roots by mini-cuttings, percentage of mini-cuttings with callus, live, dead, with shoots and leaves that maintained their original leaves were evaluated. Rooting percentages of mini-cuttings were greater than 75% regardless of the season of the year in which the propagules were collected. The adventitious root formation of D. brasiliensis occurs indirectly, from the callus tissue formed at the base of the mini-cuttings. The mini-cuttings technique is recommended for the production of seedlings of the species, at any seasons of the year.

Resumen

ABSTRACT The Australian species Melaleuca alternifolia Cheel. has a strong commercial importance due to the extraction of essential oils from its leaves used in the cosmetic and pharmaceutical industry. In order to obtain an efficient plant production system of M. alternifolia the mini-cuttings technique and the clonal mini-garden management in the productivity and rooting of mini-cuttings and different substrate compositions were analyzed during all the seasons. Mini-stumps derived from cuttings and grown in pots (2 L), were submitted to successive harvesting of their sprouts during the four seasons (september/2013 to august/2014). From the mini-stumps sprouts mini-cuttings were produced, wich were were planted in plastic tubes and kept in a greenhouse for 45 days. Six substrates were used for planting the mini-cuttings: commercial substrate (S1); substrate composed of 100% carbonized rice husk (CRH) (S2); substrate composed of 100% coconut fiber (CF) (S3); substrate composed of 50% CF and 50% CRH (S4); substrate composed of 30% CF and 70% CRH (S5); substrate composed of 70% FC and 30% CRH (S6). The high survival of mini-stumps (over 90%) and the mini-cuttings production (282 mini-cuttings.m-2.month-1) in the shade house demonstrate the technical feasibility for the species, being summer the most appropriate time to collect propagules. The substrate composed by 70% CF + 30% CRH (S6) shows superior results for vegetative propagation of M. alternifolia (91.7% of rooted mini-cuttings), as the single one to contemplate simultaneously all parameters. Summer is recommended as the best time for rooting of mini-cuttings.

Resumen

ABSTRACT: This study aimed to evaluate the rooting capability of apical and nodal mini-cuttings of ipe-roxo ( Handroanthus heptaphyllus ) in different substrates. Shoots produced from mini-stumps were fractioned into mini-cuttings 2-cm long apical or nodal mini-cuttings and treated with 1000 mg L-1 of indolebutyric acid (IBA). Four substrate combinations were evaluated: commercial substrate composed of pine bark and vermiculite in proportions of 1:1, 2:1 and 1:2 (v /v) and commercial substrate, vermiculite and sand in the proportion of 1:1:1 (v/v). The factorial experiment utilized a completely random design, with five replicates of four mini-cuttings. Rooting, shooting and survival percentage, number and length of shoots and roots were evaluated at 60 and 90 days of growth. Commercial substrate and vermiculite are a good combination for rooting mini-cuttings of ipe-roxo. Apical and nodal mini-cuttings exhibit similar rooting behavior and both are feasible for production of ipe- roxo plantlets.

Resumen

AbstractIlex paraguariensis, commonly known as yerba mate, is a tree species native to South America. Its commercial value is due to the manufacturing of teas, with potential also in the pharmacological and cosmetic industries. Vegetative propagation of yerba mate is considered an innovation to the traditional production systems based on sexual propagation. The present study aimed to evaluate the rhizogenic potential and chemical attributes of mini-cuttings from 15 yerba mate genotypes, as well as to verify the correlation between phytochemical and rooting-related variables. Mini-cuttings were collected from a pre-existing mini-clonal hedge and the experimental design was completely randomized, with 15 treatments (genotypes), four replications and 10 mini-cuttings per plot. After 120 days, mini-cuttings were assessed regarding rooting, mortality, callogenesis and leaf retention percentages, percentage of mini-cuttings with both calluses and roots, number of roots and average root length. At the time of collection, subsamples from each plot were used for phytochemical analyses including total phenolic compounds, protein, caffeine and theobromine contents and antioxidant activity. Rooting percentages ranged from 5 to 72.5%, with significant variation among genotypes. Adventitious rooting and phytochemical profile of yerba mate mini-cuttings are genotype-dependent. Leaf retention is a relevant factor in the rooting of yerba mate mini-cuttings and the levels of total phenolic compounds, antioxidants and theobromine present in mini-cuttings are negatively correlated components to Ilex paraguariensis adventitious rooting.

Resumen

The current expansion of the forest sector in the Cerrado (Brazilian Savannah), especially of the species of genus Khaya sp. (African Mahogany), requires several silvicultural and technical studies of various natures. Seed and clonal propagation enable noble and vigorous seedlings, which will future compose commercial plantations aiming timber production. The species Khaya grandifoliola C. DC is considered of distinct wood characteristics and with great economic potential. The objective of this work was to evaluate the effect of different indolbultyric acid (IBA) concentrations – between 0 and 12 g.L-1– on the rooting of K. grandifoliola cuttings and mini-cuttings. The experiment was carried out at the "Mudas Nobres" private nursery, located in Goiânia (Goiás State, Brazil). The experiment was conducted in a completely randomized design in a 5 × 2 factorial scheme. Each treatment consisted of four replications with 20 cuttings (clonal origin) or mini-cuttings (seed origin) per repetition. Models were also applied to estimate the number of shoots in clonal cuttings, according to the data observed in seed mini-cuttings. The results indicate that IBA has the opposite effect on the two evaluated types of propagule origin, being more suitable for seed mini-cuttings (should apply 8 g.L-1of IBA) and less for clonal cuttings (should not apply IBA). If a standard application must be recommended (to cuttings either mini-cuttings), the most appropriate concentration is 6 g.L-1of IBA.

Resumen

Sweet potatoes are a very important crop and genetic improvement works are necessary. Each plant originated from a botanical seed is a new cultivar, being important its multiplication. The objective of this work was to evaluate the production of sweet potato seedlings from mini-cuttings from different varieties from the same parents. The treatments consisted of mini-cuttings of 38 varieties and of their Londrina and Uruguaiana parents. The experimental design was in randomized blocks, with three replications. The following characteristics were evaluated: percentage of mini-rooted cutting and survival of seedlings after transplanting. The average minirooted cuttings was 91.4%. The survival rate in the field was above 99%. However, there was difference among the varieties mainly regarding the mini-rooted cuttings (values between 100% and 62.9%). It was concluded that the production of seedlings from mini-cuttings is a viable tool for genetic material multiplication from Londrina and Uruguaiana varieties crossing in programs of improvement.

Resumen

The use of rootstocks originated from sexual propagation results in serious problems for peach culture, being vegetative propagation an important alternative to minimize these problems partially. Among vegetative propagation methods, the use of mini-cuttings constitutes an innovation against the conventional mini-cutting method, which, in some species, have promoted an increase in productivity, uniformity and rooting percentage. Thus, the objective of the present work was to evaluate the viability of Japanese apricot propagation through herbaceous mini-cuttings, by testing different concentrations of IBA (0, 1.000, 2.000 e 3.000 mg.L-1) and types of mini-cuttings (apical, median and basal), in a completely randomized design with four replications. Prepared with two buds and a leaf cut in half, with two lesions on the basis, they were immersed in IBA solution, for 10 seconds, and placed in transparent, articulated plastic packages with vermiculite growing medium. Next, they were placed in a greenhouse under controlled temperature. Sixty days after installation, the percentage of rooted mini-cuttings, number and length of the three largest roots were evaluated. During rooting, the apical, median and basal mini-cuttings showed higher percentage using 1.000 mg.L-1 of IBA.

Resumen

The techniques of plant multiplication, when tested with native fruit trees, have proved to be limiting in several aspects, signaling that another technique should be tested, which might be recommended for the usage, especially in the jabuticaba trees which present a higher potential. The aim of this study was to test the usage of asexual propagation through mini-cuttings in jabuticabeira of cabinho according to the collection time, mini-cutting length and concentration of IBA. The work was performed at Federal Technological University of Paraná (UTFPR) – Campus Dois Vizinhos, Brazil. The samples were collected bimonthly. Mini-cuttings (6 or 8 cm) with pair of leaves reduced to 25% of the original size were prepared. The mini-cuttings had their base immersed in liquid solution of indole-butyric acid (0, 3000 and 6000 mg L-1) and placed in plastic tubes containing commercial substratum. The experimental design was completely randomized with 2 x 3 x 6 factorial (cutting length x IBA concentration x time of the year), with four replications, the experimental unit varied according to the number of shoots obtained. After 120 days of implementation of each collection, the parameters rooting and callogenesis (%), average number of roots per mini-cutting and average root length were evaluated. After 60 days the survival of post-planting rooted mini-cuttings was evaluated. It is recommended that for the jabuticabeira of cabinho, the collection period for propagation through mini-cuttings should be in August.

Resumen

Seeds of the species Inga edulis are recalcitrant and lose viability quickly, which restricts seedling production at only a certain time of the year. Thus, this study aimed to analyze the potential of mini-cutting and the influence of different indole-3-butyric acid (IBA) concentrations on the vegetative propagation of Inga edulis. The vegetative material was collected from juvenile plants from a clonal mini-garden. The experiment was carried out in a completely randomized design, with five replications and each experimental unit with eight cuttings. Treatments consisted of different IBA concentrations (0, 1000, 2000, 4000, and 8000 mg kg−1). The percentage of live and rooted mini-cuttings, number of roots emitted from the base, longest root length, total number of roots, fine root length, total root length, root surface area, weighted average root diameter, root volume, shoot dry matter, root dry matter, total dry matter, specific root length, specific root surface area, and root density were analyzed after 45 days in a greenhouse. All Inga edulis mini-cuttings survived, and rooting was over 85%. IBA concentrations had no significant effect on most of the analyzed variables. However, exogenous auxin concentration between 2000 and 4636.96 mg kg−1 provided mini-cuttings with a higher number of roots, surface area, and root volume. Rooting of juvenile Inga edulis mini-cuttings may occur without the use of IBA.

Resumen

The objective of this study is to evaluate the effectiveness of the antioxidants ascorbic acid and polyvinylpyrrolidone (PVP) in the rooting of mini-cuttings for three clones of Eucalyptus urophylla x Eucalyptus grandis. Mini-cuttings were gathered from a mini-clonal hedge which had been cultivated in concrete ducts containing washed sand. Five concentrations of each antioxidant were experimentally tested on each of the three clones (C1, C2 and C3). Assessments were done of mini-cutting survival and rooting rates when leaving the greenhouse and the shade house, as well as seedling survival and growth at age 50 days. Ascorbic acid was found to be beneficial to the mini-cuttings of the clone with a lower rooting percentage (C3), whereas PVP was found to be unbeneficial to the clones being studied.

Resumen

Ficus enormis is a native species with great ecological potential, especially for ecosystems restoration. The present study aimed to evaluate the rooting, root and vegetative vigor of Ficus enormis mini-cuttings and to determine its best length for the formation of seedlings. Mini-cuttings were collected from clonal mini-garden, prepared with 2 ± 0.2 cm, 4 ± 0.2 cm, 6 ± 0.2 cm, 8 ± 0.2 cm and 10 ± 0.2 cm of length and diameter of 0.5 ± 0.2 cm. The planting was carried out in plastic boxes filled with commercial substrate based on carbonized rice hulls and coconut fiber, conditioned in a greenhouse. After 45 days, were avaluated the rooting percentage, original leaf maintenance, mini-cuttings with roots and callus percentage, length of the three largest roots/mini-cutting, shoot emission percentage, number of root/mini-cutting and mortality percentage. The results showed that the mini-cuting length did not influenced the rooting percentage, callus and root formation, and root length mean. However, shoot emission, number of root and mortality were influenced by the mini-cutting length.

Resumen

A mini-ixora é uma planta ornamental propagada comercialmente por meio de estaquia e apreciada para uso em paisagismo. O enraizamento das estacas, no entanto, ocorre em baixa porcentagem, resultando em baixa produção de mudas nos viveiros. Visando otimizar a propagação vegetativa desta espécie, avaliou-se o efeito de diferentes estimuladores de desenvolvimento radicular e substratos sobre o enraizamento de estacas da mini-ixora. As estacas semi lenhosas com 10 cm de comprimento foram cultivadas em estufa climatizada. O delineamento experimental utilizado foi em blocos casualizados em esquema fatorial 2 x 6, sendo dois substratos (S1: 100% de areia lavada e S2: 50% de bagaço de cana + 50% de vermiculita) e seis estimuladores de enraizamento (água - testemunha; extrato de tiririca; hormônio comercial; AIB 1000 mg/L; AIB a 2000 mg/L e AIB a 4000 mg/L). Utilizaram-se quatro repetições e dez estacas por parcela experimental. Após 120 dias, foram avaliados os seguintes parâmetros morfológicos: estacas enraizadas (%), mortalidade (%), comprimento do sistema radicular, qualidade do sistema radicular e número de brotos por estaca. A propagação vegetativa das estacas de mini-ixora utilizando como substrato a mistura de bagaço de cana-de-açúcar com vermiculita proporciona maior porcentagem de enraizamento, comprimento radicular e menor porcentagem de mortalidade das estacas. O cultivo das estacas de mini-ixora no substrato composto de bagaço de cana-de-açúcar e vermiculita dispensa o uso de estimuladores de enraizamento para a obtenção de estacas com melhor qualidade do sistema radicular. Palavras-chave: Estaquia. AIB. Produção de mudas. Propagação vegetativa. Rooting of mini-ixora cuttings (Ixora coccinea l. var. compacta) under different substrates and stimulators of radicular development Abstract Mini-ixora is an ornamental plant commercially propagated by cuttings. It is a species appreciated for use in gardens. The rooting of the cuttings, however, occurs in a low percentage, which results in low production of plants. In order to optimize the vegetative propagation of this species was studied the effect of different stimulators and substrates on rooting of mini-ixora cuttings. Cuttings with 10 cm were grown under controlled conditions. The experimental design was randomized blocks in a factorial scheme 2 x 6; two substrates (S1: 100% washed sand and S2: 50% sugarcane bagasse + 50% vermiculite) and six rooting stimulators (water; tiririca extract; commercial hormone; IBA 1000 mg/L; IAB 2000 mg/L and IBA 4000 mg/L). We used four replications and ten cuttings per experimental plot. After 120 days, we evaluated the following morphological parameters: percentage of rooted cuttings, percentage of mortality, length of the root system, root system quality and number of shoots per cutting. The vegetative propagation of the mini-ixora cuttings using as substrate a mixture of sugarcane bagasse with vermiculite provided the highest percentage of rooting, root length and lower percentage of mortality of the cuttings. The cultivation of mini-ixora cuttings on the substrate composed of sugarcane bagasse and vermiculite does not require the use of rooting stimulators to obtain cuttings with good quality of the root system. Keywords: Cuttings. IBA. Seedling production. Vegetative propagation.

Resumen

Background: This study aimed to evaluate the growth ability of cassava mini stem cuttings with different node number and a variety of stem cutting shapes and their correlation with starch content in the stems at initial growth stages. Methods. In this study, the viability of cassava stem cuttings was identified in two type experiments i.e. mini-stem cuttings consisting 1 and 2 nodes and shape variation of single node mini-stem cutting. Parameters observed were shoots emergence period, number of sprouting cuttings, shoots number of individual stem cuttings, shoots height and number of leaves. In addition, starch histochemical test was also carried out on stems of young shoots and initial stem cuttings using Lugol’s solution. Results. Both cassava stem cuttings consisting of 1 and 2 buds indicated the same survival rate of 100%. 1 bud stem cuttings with different shapes showed different survival rate, i.e. 60-80% for semicircular and fully circular cuttings and 30-40% for box shape cuttings. The difference in survival rate with different stem size is probably related to the availability of the amount of starch to support shoots growth. Observations at week 3 after planting generally showed that the stem cuttings with 2 buds were higher than those of stem with 1 bud. Conclusion: There were differences in the scores on the starch content test qualitatively with Lugol staining, in various parts of the plant originating from 1 bud and 2 bud cuttings which may indicate a breakdown of starch during shoot development.

Resumen

Guava (Psidium guajava L.) is a plant whose fruit is very popular in Indonesia because it contains high vitamin C and its leaves can be used as herbal medicine. Orchard expansion of selected cultivars and fruit production of guava can be achieved vegetatively through propagation by using mini-cuttings with the use of Indole Butyric Acids (IBA). A study was conducted to compare rooting success of mini-cuttings of herbaceous stem of four guava cultivars with IBA treatment. Four guava cultivars tested were Bengkulu Round, Getas, Crystal, and Bangkok. Mini-cuttings were immersed in IBA solution at 0 ppm or 1000 ppm. Cultivar and IBA treatments were arranged factorially in a randomized complete block design with 3 replications, each consisting of 25 cuttings. Variables observed included percentage of original-leaf shedding, percentage of emerging shoots, percentage of sprouting cuttings, new leaf number, root number, root length, and percent of rooted cuttings. The results demonstrated that cultivars affected rooting percentage, sprouted percentage, percentage of original-leaf fall, and number of root. Getas had highest rooting and sprouting percentages, and showed lowest number of original-leaf shedding; whereas, Bangkok demostrated greatest number of root. IBA treatment increased the number of root and the number of original-leaf shedding, but reducing rooting percentage of mini-cutting. There was no interaction between cultivar and IBA teratment.

Resumen

Mini-cutting technique of tree species is an effective method of maintaining desirable features of plant matrices and uniformity. The objective of the present research was to determine substrate and concentration of indolebutyric acid (IBA) more suitable for mini-cuttings of Carya illinoinensis rooting. The experiment was carried out in a greenhouse with mist, from February to May 2018. The used experimental design was in blocks with a factorial arrangement of 3 x 5, in which three substrates were tested: carbonized rice husk, vermiculite and perlit; and five IBA concentration : 0, 2,000, 4,000, 6,000 and 8,000 mg L-1. The mini-cuttings were apical, produced from seedlings, with eight months of age. Mini-cuttings were made with two leaves cut in half and 8 to 10 cm in length. The use of IBA influenced results obtained with all substrates, except for the variable number of roots, in which only IBA effect was observed. However, higher results were obtained with IBA uses together with substrate carbonized rice husk, obtaining estimated maximum point of 91% of rooted mini-cuttings with 3,957 mg L-1 IBA concentration. For other evaluated variables, except root numbers, it was also observed superior results close to 4,000 mg L-1 IBA concentration with substrate carbonized rice husk. Results indicate the possibility of Carya illinoinensis propagation by mini-cutting technique and as an alternative for this specie plantlets production.

Resumen

The objective of this study was to evaluate the influence of length of herbaceous cuttings and substrates on the multiplication of ‘Woodard’ and ‘Briteblue’ blueberry cuttings. The experimental design was entirely randomized. Four replicates of 10 cuttings per plot in a 3x2 factorial arrangement, three cutting lengths (5, 8, and 12 cm) and two types of substrate (rice hull ash and coconut fiber) were evaluated. The cuttings were collected in two seasons: summer and fall. After the cuttings were prepared, they were placed in perforated plastic boxes containing each substrate for rooting, which were placed in a mist chamber under intermittent mist. After 158 days, the following variables were evaluated: proportion of rooted cuttings, cutting survival, leaf retention, number of roots per cutting, root mean length, root dry mass, unrooted cuttings with callus, and the proportion of sprouting cuttings. The use of 5-cm herbaceous cuttings collected in the summer and grown in rice hull optimizes the multiplication of ‘Woodard’ and ‘Briteblue’ blueberry cuttings.

Resumen

The viability of the mini-cutting technique requires seedling regrowth ability and continuous propagule production. It is hypothesized that the application of gibberellic acid (GA) can stimulate vegetation and increase the production of mini-cuttings. The aim of this study was to increase the mini-cutting yield of Psidium guajava (L.) × Psidium guineense (Sw.) (‘BRS Guaraçá’) as a function of foliar application of GA and season of the year. The experiment was laid out in a randomized-block design with split-plots in time, in which the plots consisted of different GA concentrations applied (0, 50, 100, 150 and 200 mg L-1) and the subplots were represented by two application periods or seasons (summer and winter). Four replicates were used, with two plants per plot. After the seedlings were topped, GA was applied at different concentrations and the emerged shoots were evaluated over 30 days. Mini-stump yield was assessed by collecting and evaluating the potential number of mini-cuttings. Shoot length and mini-stump yield increased linearly with the increasing GA concentrations during the summer. In the winter, this response was quadratic, with optimal concentrations estimated at 65.3 mg L-1 for shoot length and 76 mg L-1 for mini-stump yield. The GA concentration of 200 mg L-1 provided shorter internodes in the summer, whereas in the winter the use of GA did not interfere with this trait. The increasing applications of GA induced a linear increase in stem diameter at both seasons of the year. Gibberellic acid did not interfere with the rooting of the mini-cuttings. The highest rooting percentage occurred in the summer, with an average of 95%. In the winter, this value was 77.2%, demonstrating that mini-cuttings are a promising technique for ‘BRS Guaraçá’. Foliar spraying of GA promoted an increase in mini-cutting production, without interfering with their rooting.

Resumen

ABSTRACT This study aimed to evaluate IBA efficiency in mini-cuttings rooting based on four Tectona grandis clones. Vegetative samples were collected in a hydroponic mini-clonal hedge in Verde Novo reforestation company at Colider, Mato Grosso. A factorial arrangement (4 x 6) was utilized, based on Carapá, Ipê, GU5 and TB7 clones vs six IBA dosages (0, 1000, 2000, 4000, 8000 and 16000 mg L-1), in a randomized block design based on three repetitions and 16 mini-cuttings per experimental unit. Cutting evaluations were based on survival and rooting rates after greenhouse conditions, after shadow-house, and at sun exposure, besides, total height, collar diameter, aerial and root biomass were also analyzed. Results registered a 95,4% average survivance rate as well as a 91,8% rooting rate, considered as very high for this tree species. IBA dosages utilization did not produce a significative effect on rooting mini-cuttings from these investigated clones. However, there were different responses among clones, which suggests a genotypic effect.

Resumen

In this work, we analyzed the correlation between the canopy coverage of two commercial clones of Eucalyptus benthamii Maiden & Cambage and one of Eucalyptus dunnii Maiden and their shoot yields in a clonal mini-garden system. By canopy coverage, we referred to the area of a picture occupied by leaves (green area) when analyzed using computational resources. The mini-garden was set up to yield shoots on a regular time schedule (between 20 and 30 days) to obtain mini-cuttings for clonal propagation. Pictures were taken at approximately 30 cm above the upper leaves from the plots containing mini-stumps of each clone on the day before the collection of mini-cuttings for six consecutive harvests (approximately 6 months). The leaf coverage was obtained using the computational package Easy Leaf Area. Our results indicated a significantly high Pearson correlation coefficient (r = 0744, P < 0.001) between the canopy coverage and the number of shoots produced by each clone. A logistic regression model was adjusted to this dataset, enabling a prediction of the number of shoots based on the canopy coverage. This approach has the potential for assisting forest nurseries in predicting the yield of mini-cuttings while conducting clonal propagation of their genetic materials.

Resumen

The objective of this study was to evaluate the viability of the Ginkgo biloba mini-cutting technique, as well as the influence of substrates and different concentrations of indole butyric acid (IBA) on adventitious rooting in addition to the protein and sugar content in the mini-cutting. Mini-cuttings were 4 ± 1 cm in length, with the bases immersed in solutions of 0, 1000, 2000, and 3000 mg L-1 IBA. They were then planted in polypropylene tubes using two substrates (vermiculite and Tropstrato®) and maintained under greenhouse conditions for 60 d. The experiment was carried out with a 2 × 4 factorial scheme (substrates × IBA). There was no influence of IBA application on the promotion of rhizogenesis in Ginkgo biloba mini-cuttings. The rooting percentages were higher than 55% regardless of the treatment used. The vermiculite substrate showed a higher number of roots (4.94) and lower mortality (11.60) of mini-cuttings than Tropstrato®. We conclude that the mini-cutting technique is feasible for Ginkgo biloba, and the use of IBA is not necessary. We found that the induction ofadventitious rooting depended on the biochemical composition of the mother plants, due to the translocation of non-reducing sugars and leaf proteins for root formation.

Resumen

The objective of this study was to evaluate the morphophysiological quality of yerba mate plantlets (Ilex paraguariensis A. St.-Hil.) produced by mini-cutting at four different times of year and cultivated in different containers. For the rooting of mini-cuttings, shoots of four yerba mate clones were collected four times during the year (April, July and October 2014 and January, 2015), cut into single-budded mini-cuttings and planted in equal proportions of pine bark-based commercial substrate, vermiculite and coarse sand. After 60 days of cultivation in a wet chamber, the rooted mini-cuttings were transferred to different containers: a 100 cm³ rigid polyethylene tube container and 500, 1500 and 3000 cm3 polyethylene bags containing pine bark-based commercial substrate and underground soil (2:1 v/v). A completely randomized design was used in a 4 x 4 factorial scheme, with five replications ranging from 5 to 20 mini-cuttings per experimental unit. The plantlets were evaluated for survival percentage, shoot height, stem diameter, shoot height/stem diameter ratio and number of leaves at 30, 60, 90 and 120 days of cultivation. At 120 days of cultivation, 10 plantlets from each treatment were randomly picked to evaluate shoot and root dry mass, Dickson quality index, shoot height, surface area, total volume and number of root tips. The best combinations of shoot height, length, surface area, total volume and number of root tips and Dickson quality index were found in plantlets produced in July, 2014, followed by plantlets produced in October,2014 and January, 2015. The polyethylene bags allowed the production of yerba mate plantlets with satisfactory quality of shoot and roots, regardless of the volume. Yerba mate plantlets can be produced by mini-cutting from July to January in polyethylene bags.

Resumen

The use of Brazilian native species for ornamental purposes is a promising alternative for local floriculture. Seeking to contribute with new information in this context, the present study aimed to evaluate the rooting performance of mini-cuttings from three Tibouchina species (T. aff. fothergillae, T. heteromalla and T. moricandiana var. vinacea) as affected by the use of indolebutyric acid (IBA) and fulvic acid (FA). Mini-cuttings with 5 cm in length were prepared with plant material from clonal mini-hedges and submitted to different treatments as follows: control treatment (T1); 2,000 mg L-1 IBA (T2); 2,000 mg L-1 FA (T3) and 2,000 mg L-1 IBA + 2,000 mg L-1 FA (T4). Planting was carried out in plastic containers filled with vermiculite, and, after 26 days under greenhouse conditions, the following variables were evaluated: mini-cuttings rooting percentage (RP), roots number (RN), roots length (RL), initial leaves maintenance (ILM) and sprouting (SP). The experiment was conducted under a completely randomized design in a 3 x 4 factorial scheme, with four replications and 20 minicuttings per plot. Rooting percentages were higher than 90% in all three species, regardless of IBA or FA treatments. RP, ILM and SP did not show statistically significant interaction between the treatments. For RN, T2 and T4 promoted the best results on T. aff. fothergillae (12.62 and 14.92, respectively) and T2 resulted in maximum values for T. heteromalla (15.65). For RL, T2 and T4 were statistically superior on T. heteromalla (9.52 and 8.20 cm, respectively). The use of IBA and FA is dispensable for rhizogenesis induction on mini-cuttings from the studied species

Resumen

The objective of this work was to determine the most adequate substrate and indolbutyric acid (IBA) concentration for the ex vitro rooting of the “Xavante” and “Tupy” blackberry and the “Heritage” and “Fall Gold” raspberry mini-cuttings. Explants were transferred to a laminar flow chamber and placed in a MS nutrient medium, giving origin to mini-cuttings whose bases immersed in four different IAC concentrations (0 mg.L-1, 1000 mg.L-1, 2000 mg.L-1, 3000 mg.L-1). Next, they were placed in transparent and articulated Sampack® (10 x 13 x 20) plastic bags with two types of substrates (vermiculite and vermiculite + coconut fiber, in the proportion of 1:1 v/v). For the number of roots variable, vermiculite substrate associated with coconut fiber showed representative results for the Tupy cultivar. However, for the Heritage cultivar, satisfactory results were obtained for the same variable with vermiculite substrate. One point of maximum efficiency was observed with the 1800 mg.L-1 IBA concentration. Results showed that the ex vitro rooting of blackberry and raspberry mini-cuttings may be realized without immersion in an IBA solution. Therefore, the use of vermiculite associated with coconut fibber is the most recommended.

ABSTRACT The use of mini-cuttings is an option for obtaining sweet potato propagules of excellent quality. The objective of this research was to evaluate the production and quality of sweet potato roots propagated by mini-cuttings in different types of trays and ages of seedlings. Six treatments, resulting from the factorial 2x3, were evaluated: two types of trays (162 and 200 cells, with 31 and 18 mL of substrate per cell, respectively) and three ages of seedlings (39, 46 and 53 days after placement of mini-cuttings in trays), in a randomized block design, with five replications. Seedlings characteristics, production and quality of roots were evaluated. Higher number and dry weight of leaves per seedling were observed in the tray with 162 cells than in trays with 200 cells. The younger seedlings (39 days) had a lower number of leaves, dry weight of leaves, stem, roots ant total (leaves + stem + roots) than seedlings of other ages. There was no difference in root production depending on the type of tray, regardless of the age of the seedlings. For the 162-cell tray, the age of the seedlings did not affect the production of roots. On the other hand, for the 200-cell tray, higher roots production was observed on seedlings 39 days age compared to seedlings with 53 days. No differences were observed among the roots of different treatments for titratable acidity, and levels of sucrose, reducing sugars ant total sugars. It is recommended to avoid old seedlings, that is, it is recommended to use seedlings with a maximum of 43 days after planting of mini-cuttings for trays with 200 cells, while for trays with 162 cells no difference in root production was observed with the different ages of the seedlings.

ABSTRACT The objective of this study was to evaluate the effect of the growth regulator indole butyric acid (IBA) on the rooting of mini-cuttings of Castanea crenata x C. sativa hybrid clones. Minicuttings were left to root for 60 days in an acclimatized greenhouse and then transferred to a shade house for a further 30 days. The experiment was a random block design with a double factorial arrangement consisting of five IBA concentrations (0, 2,500, 5,000, 7,500 and 10,000 mg L-1) and five clones, with three repetitions, composed of eight minicuttings per repetition. The use of IBA significantly affected the rooting and survival of the mini-cuttings, and good rates were achieved. However, at each IBA concentration we found significant differences between clones, thus suggesting that the conditions of the process of mini-cutting propagation should be specifically adapted to each particular clone.

A trial involving the mass propagation of Argania spinosa cuttings was established following two protocols: in mini-bouturathèques without mist and in a greenhouse under mist. Symptoms of petiole necrosis, foliar yellowing and abundant black acervuli were observed under both protocols. These symptoms were responsible for a 90% mortality rate in the mini-bouturathèques while under the mist treatment premature fatal necrosis of the apical buds resulted in 100% mortality. The disease’s causal agent, Pestalotiopsis clavispora, was identified on the basis of its morphological characteristics and by molecular analysis. Alternating weekly treatments of systemic and contact fungicides resulted in a 41% success rate in controlling this pathogen, described for the first time on argan cuttings.

Resumen

Sugarcane is a commercially important species for sugar and biofuel production and because of the high demand for plant material in planting, new means of propagation are being developed and require improvements. Therefore, the objective of this study was to evaluate the effect of different concentrations of indole-butyric acid (IBA) applied in the form of talc on the initial growth and emergence of sugarcane mini-cuttings used for the system of pre-sprouted plantlets (PSP). Mini-cuttings were treated with concentrations of 0, 500, 1000, 1500 and 2000 mg kg-1 of IBA in the form of talc and evaluated for emergence and initial growth. There was no difference between IBA concentrations for the physiological, biometric and dry mass variables analyzed. The sugarcane plantlets formed had emergence above 89%, functional photosynthetic apparatus, 4.4 leaves on average, stem diameter of 11.90 mm, shoot length of 12.18 cm, leaf area of 108.81 cm² and root area of 142.17 cm². Shoot dry mass and root dry mass were equal to 2.27 and 1.20 grams, respectively. Thus, concentrations of up to 2000 mg kg-1 of IBA applied in the form of talc in sugarcane mini-cuttings had no effect on rooting and initial growth of plantlets.

Resumen

The aim of this study was to verify the influence of mini polytunnels on the quality of shoots produced in a black wattle clone garden. The treatments used were: T1 – clone garden with mini polytunnels inside the greenhouse; T2 – clone garden with no mini polytunnels inside the greenhouse; T3 – clone garden with mini polytunnels outside the greenhouse; and T4 – clone garden with no mini polytunnels outside thegreenhouse. These four treatments formed a 4 x 3 factorial along with three seasons of the year: winter/2015, summer/2015-2016, and autumn/2016. A randomized block design was used with six blocks and ten cuttings per plot. Survival rate, number of shoots per cutting, and mean shoot length were evaluated. Shoots were collected from the cuttings and a rooting experiment with the same design was installed. Rooting rate, rate of shoots with calluses, number of roots per shoot, and mean shoot length per cutting were evaluated. There was interaction between the environment in the clone garden and the season of the year. In the winter, the treatment with mini polytunnels outside the greenhouse (T3) showed the best results, mainly in what concerns to the rooting of shoots. Shoots survived in the four clone garden environments, and the lowest survival rates were observed in the autumn/2016 season. The best responses were observed in the summer season.

Resumen

A estaquia de genótipos superiores de Pinus radiata é uma prática comum na silvicultura. Para sua utilização no Brasil, protocolos de propagação precisam ser estabelecidos. Este trabalho avaliou a miniestaquia aplicada à produção de mudas da espécie, estudando a posição de coleta de broto na planta matriz, a estação do ano e o minijardim. Plantas matrizes seminais, com 1 m de altura e 1,5 anos de idade, foram utilizadas para a produção de miniestacas. Três ensaios consecutivos foram feitos: (i) o enraizamento das miniestacas coletadas de três posições nas matrizes (topo, intermediário e basal), (ii) a influência do minijardim (vaso, canaletão e campo) no desenvolvimento de minicepas e (iii) o efeito da estação do ano (inverno, primavera e verão) sobre o desenvolvimento de miniestacas coletadas de minicepas no canaletão, no vaso e em campo. As miniestacas coletadas da região intermediária das matrizes, com 1,5 anos de idade, apresentaram maior enraizamento do que as coletadas no topo e na região basal. As melhores estações para o desenvolvimento dos brotos foram inverno e primavera, em ambientes de vaso e campo. O verão promoveu melhor desenvolvimento das miniestacas em casa de vegetação, a partir de matrizes cultivadas em canaletão.Palavras-chave: Clonagem; conífera; produção de muda; propagação vegetativa. AbstractEffect of matrix plant, season and minigarden on Pinus radiata minicutting. Cutting of superior genotypes of Pinus radiata is current in forestry. For such practice in Brazil, protocols of propagation need to be established. We evaluated the mini-cutting applied to seedling production, focusing the collection point in matrix plant, season, and minigarden. We used seminal matrix 1 m height and 1.5 years old for mini-cutting production. Three consecutive trials were made: (i) the rooting of mini-cuttings collected from three points in the matrix (top, intermediate and basal), (ii) the influence of minigarden (pot, gutters and field) in development of rooted, and (iii) the effect of season (winter, spring and summer) on the development of rooted cuttings collected in pot, gutters and field. The mini-cuttings collected from the intermediate region of the 1.5 years old seedlings matrices had higher rooting than those collected from the top and basal region. The best time for the development of buds was winter and spring in pots as well as field environments. Summer promoted the best development of mini-cuttings, in greenhouse, from matrix plant grown in gutters.Keywords: Cloning; conifer; seedling production, vegetative propagation.

Resumen

The use of mini-cuttings in the production of peach seedlings may prevent the inconvenience of grafting and make possible the fast, simple and low-cost production of a great number of seedlings, in a shorter period of time. Seedlings collection from self-rooted scion cultivars may be an option for locations where the use of rootstock does not offer any specific advantage. The objective of the present experiment was to evaluate the growth and survival of self-rooted peach scion cultivars cloned through mini-cutting under the soilless cultivation system and in packages with commercial substrate, in a greenhouse. The experimente used rooted herbaceous mini-cuttings from the Maciel and Bonão scion cultivars transplanted to a package with commercial substrate and to a soilless cultivation system as vegetal material. The Maciel cultivar showed greater rooting and survival percentages after transplantation when compared to Bonão. At 120 days after transplantation to the cultivation systems, self-rooted seedlings from the Maciel and Bonão cultivars reached half the length of a commercially ready seedling. The soilless cultivation system improves self-rooted peach seedlings development in relation to production in packages.

Resumen

Objetivou-se com o estudo verificar resgate vegetativo, enraizamento de estacas e adaptação das mudas enraizadas em sistema de minijardim clonal de Sequoia sempervirens. Realizou-se a decepa de cinco indivíduos com 20 anos de idade e após foi contabilizada a capacidade de emissão de brotações. Com as brotações, foram confeccionadas estacas, as quais foram submetidas a diferentes concentrações de ácido indolacético (AIA) (0, 2000, 4000 e 6000 mg.L-1). Foram avaliadas a porcentagem de enraizamento e o número e comprimento de raízes 160 dias após o estaqueamento. O experimento foi instalado em DIC, com 5 repetições de 10 estacas. Após a formação das mudas com as estacas enraizadas, elas foram transplantadas para vasos, para a formação do minijardim clonal. O resgate vegetativo através da decepa de árvores apresentou potencialidade para produção de estacas de sequoia e revigoramento do material. O uso entre 2000 e 4000 mg.L-1 de AIA aumentou a porcentagem de enraizamento e também o número e comprimento de raízes formadas. O minijardim clonal de sequoia mostrou ser uma boa opção para a multiplicação clonal da espécie. A clonagem da sequoia pode auxiliar tanto no melhoramento convencional como em plantios comerciais da espécie, principalmente no Sul do Brasil, local onde encontra condições adequadas para seu crescimento.Palavras-chave: Silvicultura clonal; coníferas; rejuvenescimento; minijardim clonal. AbstractRescue and vegetative propagation of Sequoia sempervirens.

Resumen

ABSTRACT Araucaria angustifolia is native to Brazil and has always raised economic interest for the qualities of its timber and as a supplier of pine nuts for human consumption. The scarce germination viability of the stored seeds and the possibility to produce rooted cuttings all year round make cuttings propagation a good alternative for the production of plants, giving also the possibility to obtain genetically superior clones. On this basis, we assessed the influence of stock plants sex and type of cuttings (apical and intermediate) on the percentage of survival, rooting and vigor of the cuttings, together with the efficiency of this technique in the production of rooted cuttings of this species. So, cuttings from orthotropic shoots, collected in a clonal garden composed by feminine and masculine plants, had their survival percentages assessed at 60, 90, 120 and 150 days after installation of the experiment (DAI). Rooting in full sunlight area after 180 days, together with vigor characteristics of roots and aerial portion at 120 and 180 DAI were also evaluated. At 180 DAI, apical female cuttings presented the greatest rooting percentage (53.7%), number of roots (1.2) and average length of roots at the bottom of the rooting tray (4.4 cm). On the other hand, the applied cuttings procedures showed to be adequate to increase the rooting percentages of the species, which, supported by the fact that this technique is important for the formation of rooted cuttings to be used in the mini-cuttings technique, indicates that it can be considered efficient.

Resumen

In Côte d'Ivoire, cassava production is carried out by small-scale planters who use very few technical means and local cultivars that are not very productive and susceptible to diseases. The objective of this study is to maximize the recovery of cassava cuttings after planting. To this end, ten substrates of single, double, triple and quadruple composition were made from soil supplemented with sawdust, chicken droppings, carbonized rice husks and NPK 10 18 18 to regenerate dehydrated cassava Bocou 1 and Yavo mini-cuttings. The recovery rate of the mini-cuttings was evaluated as well as the agro-morphological parameters of the seedlings for 21 days. Results showed that the recovery rate was very high on the carbonized rice husk substrate (86.5% in Bocou 1 and 85.5% in Yavo). In addition, the substrates significantly influenced the growth parameters of the seedlings. Thus, the substrate composed of carbonized chicken-bale soil had the highest number of leaves, with 6 leaves per plant in Bocou 1 and 10 leaves in Yavo, with an average height ranging from 10.99 ± 1.22 (Bocou 1) to 20.23 ± 1.16 (Yavo). The results of this study will help orient the actors of the cassava sector towards a new cultivation technique.

Resumen

The objective of this study was to compare the vegetative and productive aspects and the quality of “Maciel” peach fruits grown on ‘Flordaguard’ clonal rootstock obtained from mini-cuttings, in different grafting periods (active bud and dormant bud). The experiment was conducted in an orchard located at Centro Agropecuario de Palma, in the county of Capao Leao, by Universidade Federal de Pelotas, RS (UFPel), from 2014/15 to 2015/16. The following variables related to the vegetative aspects were evaluated: canopy volume, trunk diameter, branch diameter, plant height, phenology (initial, full and final flowering) , productive aspects, estimated productivity (t.ha-1), production (kg. plant), production effectiveness, fruit diameter and physical-chemical characteristics such as firmness, color, pH, titratable total acidity, soluble solids, soluble solids/ titratable acidity relationship, antioxidant capacity, phenolic compounds and carotenoids. The most recommended grafting method for the ‘Maciel’ peach tree on ‘Flordaguard’ rootstock propagated by mini-cuttings is the active bud grafting.

Resumen

Aim of the study: Manilkara bidentata (A.DC.) A.Chev. (‘quinilla’) is a Neotropical tree highly threatened by extensive agricultural practices and climate change, resulting in a substantial reduction of natural stands and seed availability. Commercially, the propagation through seeds of this species is severely impeded by a low germination rate. Vegetative propagation could be an alternative tool for overcoming this limitation. This study aims to evaluate the vegetative propagation of M. bidentata by rooted cuttings using mini-tunnels in the Amazon.Study area: National University of San Martín, Tarapoto, Region of San Martín, Peru. Forested areas at three localities in the Picota province and two localities in the Bellavista province, San Martín Region, were visited for the selection of plus trees and collection of epicormic shoots from stumps.Materials and methods: the study was performed on leaf areas of 0, 50, and 100% with indole-3-butyric acid (IBA) treatments of 0, 3000, and 6000 ppm, for 9 treatments combinations. The experiment consisted of 3 mini-tunnels, with 3 growth trays established on each mini-tunnel, and 16 cuttings established on each tray (and per treatment), for a total of 144 cuttings.Main results: after 55 days, the best scores in rooting rates (75%), number of roots (3.88), root length (3.26 cm), and budding percentage (94%) were obtained for the combination of 50% leaf area left with 3000 ppm of IBA.Research highlights: we propose the technique of mini-tunnel as a tool for the cloning, rescue, and germplam conservation of M. bidentata.Key words: mini-tunnel; Peruvian Amazon; quinilla; rooting; vegetative propagation.Abbreviations used: indole-3-butyric acid (IBA).
