Abstract:

Keynote paper presented at the International Leucaena Conference, 1‒3 November 2018, Brisbane, Queensland, Australia.To effectively utilize sterile hybrids of leucaena, efficient protocols for vegetative propagation are needed that meet different user requirements and capabilities. We developed and compared methods for propagating several sterile hybrids of leucaena and compared them with each other and with propagation via seeds for variety K636. Methods included air-layers, rooted cuttings, grafting and tissue culture (micropropagation). All methods required 14‒20 weeks from generation of new shoots on the stock plant to production of rooted plantlets ready to outplant as compared with 6‒8 weeks for seedlings of K636. Successful rooting was highest for air-layers and rooted cuttings. Grafting had lower success owing to a higher skill requirement for the propagator. Tissue culture showed promise, but use of field-grown material was limited by microbial contamination of propagation media. Rooted cuttings are the best option presently for operational-scale propagation, but the method requires a mist system or a carefully controlled non-mist environment. If an effective method can be developed, grafting of young shoots onto a seedling rootstock is an alternative that retains the advantages of a seedling tap root and requires fewer resources than rooted cuttings or tissue culture.

Abstract:

Next-generation biomass feedstocks are needed to optimize sustainability in a wide range of soils and climates. Species that has been recently noticed in Europe is Virginia fanpetals (Sida hermaphrodita L. Rusby). A critical question with research of this species is its field propagation. A long-term (2003–2012), field experiment was conducted to determine the impact of propagation method on yields and productivity this species. The hypothesis was higher yields of S. hermaphrodita biomass from vegetative propagations than from generative propagations, also over the long term. On average, from first 10 years of lifespan of Virginia fanpetals (2003–2012), biomass dry matter (DM) yields were significantly higher by vegetative propagation (16.8 Mg ha–1) as for generative (10.9 Mg ha–1). The average gross energy yield obtained by the vegetative propagation reached 304 GJ ha–1 while by the generative propagation was 196 GJ ha–1. The determined heat of combustion reached 18.1 GJ Mg–1 DM, the ash content was 28 g kg–1, and the nitrogen (N), sulphur (S), and chlorine (Cl) contents were 1.9 g kg–1, 0.52 g kg–1 and 0.23 g kg–1, respectively, regardless of propagation methods.

Abstract:

More than 70% of the ornamental plant species grown in Indian gardens are of exotic origin, which directly or indirectly affect the existence of indigenous vegetation of the country. In the exploration to find out the possibilities of the still to be exploited indigenous species in gardens, Gymnostachyum febrifugum Benth. a herbaceous plant endemic to southern Western Ghats of India, is systematically evaluated here for its aesthetic potential. Very poor percentage of seed germination was found the major cultivation constrain. The highly condensed stem restricts vegetative propagation also. A successful vegetative propagation method using single noded stem sections and node splits with single axillary buds is developed. Being vegetative propagation means, it also helps to retain the selected desirable qualities uniformly through generations.

Abstract:

Dipterocarpaceae dominate plants of tropical forests, and their wood is exploiting until it's been rare plants. Conservation through generative propagation has several problems, and vegetative propagation then being as an alternative. This study has two purposes that to understand the history of distribution of Dipterocarpaceae and do research about the development of vegetative propagation techniques that apply for Dipterocarpaceae. This study was using a systematic review method. Commonly, vegetative propagation techniques that have been applied are cuttings and culture in vitro but other vegetative techniques have not to use yet. Research on the vegetative propagation of Upuna and Parashorea has not been available. Cutting is the most propagation technique used and has a good effect on several species of Dipterocarpaceae. Culture in vitro techniques have been used for several genus and need further research. Keywords: conservation, dipterocarpaceae, rare tree, systematic review, vegetative propagation

Abstract:

Piperaceae species of forest remnants of Maringá, Paraná, Brazil present vegetative propagation through root or stem (stolon). This reproduction type was verified in Piper amalago L., P. arboreum Aublet, P. xylosteoides (Kunth) Steud., Peperomia parnassifolia Miq. and Ottonia martiana Miq. Root and stem branches of these species were analyzed anatomically. Results indicated that the vegetative propagation in Piperaceae should be studied in other forests. New and additional studies should be made if the structural variations were induced environmentally or fixed genetically.

Abstract:

Vegetative propagation is a fantastic way to improve the quality of the forest tree planting stock. It is often used in seed orchards and clone banks as a method of genotype preservation. Vegetative propagation is the greatest option when low quality seed and poor germination rates limit the availability of planting stock and quality. This review article discusses different vegetative propagation methods, including macro-propagation by cuttings, micropropagation through tissue culture, and grafting. Having insufficient knowledge and experience is the biggest obstacle to employing vegetative propagation. Therefore, an effort was made to outline several techniques together with their history and significance.

Abstract:

This article presents the process of accelerated reproduction of healthy clones of grapes, including the following stages: growing young shoots of the original plants of clones, introducing tops into in vitro culture, microclonal cuttings, adaptation of microplants to ex vitro culture, transplanting into cassettes with a soil substrate, transferring plants to a greenhouse for growing to the condition of vegetative seedlings and planting in a pre-propagation mother stock. For the successful implementation of each of the above operations in the SPIHVFT, a Cultural Complex has been equipped, consisting of a number of interconnected premises: a sterile box, a culture chamber and a vegetation chamber. The use of this Complex allows multiplying the required number of plants during the year, to grow vegetative seedlings by the spring of the next year and plant them in the pre-propagation “Pre-base” mother plant. After a year, grafted vegetative seedlings grown from the vines of the mother plant were used for laying the mother stock.

Abstract:

Abstract: Understanding the mechanisms involved in tree species maturation, related mainly to ontogenetic age effects, has contributed significantly to the vegetative propagation process of Brazilian native tree species, with consequent application of clonal forestry. A number of methodologies has been developed to rescue and vegetatively propagate these species for silvicultural and environmental restoration purposes. However, the types and purposes of propagation, as well as the choice of suitable processes and propagules considering the intended objectives, still need to be better aligned. In addition, there is an evident knowledge gap and great potential regarding the use of native tree species in Brazilian clonal forestry, indicating the need of a greater interaction between studies on the vegetative propagation and vigor of these materials in the field. Therefore, this review aims to help understand the different types of techniques used and their application on the vegetative propagation and clonal forestry of Brazilian native tree species, besides proposing a schematic sequence of the stages involved in these processes for productive and environmental purposes.

Abstract:

Abstract The desire to propagate plants with useful and predictable characteristics vegetatively has been a major concern since the beginning of agriculture. Clonal propagation of apple varieties by grafting onto rootstocks dates back to ancient times (72). A range of techniques for vegetative propagation have been developed over the years, including advances in layering, rooting cuttings, grafting and budding, and the relatively recent approach of micropropagation (31). Vegetative propagation is costly and inefficient compared to seed propagation. For crops with short generation time, repetitive inbreeding or hybrid crosses of inbred lines allows the propagation of nearly genetically uniform populations by sexually produced seed (1). However, generation time in perennial tree crops, including Malus spp., is too long to make this approach practical. As a result, sexually produced seedling populations are highly variable. For this reason, the limited numbers of apomictic species among perennials constitute extremely valuable exceptions, allowing efficient propagation of genetically uniform populations from seed.

Abstract:

We determined that highly successful vegetative propagation is possible for Baptisia, Thermopsis and Eupatorium. This is significant because vegetative propagation of these native genera has not been widely practiced in commercial ornamental production. Seed propagation has been utilized over vegetative propagation due to historically low rooting percentages and reduced crowning (bud formation at the root-shoot union) when vegetative propagation is employed. However, vegetative propagation can enable the production of ornamental nursery stock quicker and with greater uniformity in finishing time compared to seed propagation. Vegetative propagation can also facilitate the perpetuation of threatened or endangered species that have small or isolated populations (limited sexual reproduction) or can be used to build numbers of phenotypically superior individuals without wild digging. Four model species representing three native herbaceous genera that include multiple threatened or endangered species were used in the study. Four concentrations of K-IBA (potassium salt of Indole-3-butyric acid) were examined along with 28 and 56 days in a propagation environment to determine the best rooting percentage and root quality for each species. An economic analysis was conducted to test the efficacy of treatment with K-IBA versus double-sticking two untreated cuttings. In addition to developing a commercially viable propagation protocol for these three species, we also determined that treatment with K-IBA is not necessary for successful propagation of the majority of these species, but that more time in a commercial propagation environment leads to higher rooting percentages at a reduced propagation cost.

Abstract:

The paper presents the results of a long-term (2001-2018) study of vegetative propagation methods of the Syringa L. genus varieties on the basis of the South Ural Botanical Garden Institute of the Ufa Federal Research Centre of Russian Academy of Sciences. The objective of the study was to determine the most effective and affordable ways of lilac varieties propagating in the climatic conditions of the Southern Urals, as well as to identify environmental factors affecting the effectiveness of vegetative propagation. Throughout the research period, such methods of vegetative propagation of lilac varieties as spring vaccinations, summer budding, propagation by aerial roots, green cuttings propagation were studied. As a result of the studies, it was found that the maximum quantity planting material is obtained when varieties are propagated by green cuttings using sand or a mixture of sand with perlite as a substrate. In the South Urals, greenhouses in the open ground for rooting lilac cuttings are practically unsuitable, because rooted cuttings die in them in winter or early spring. Therefore, in the climatic conditions of Bashkortostan, the rooting of lilac cuttings is desirable to be carried out in a sheltered greenhouse. With the help of spring vaccination, you can rejuvenate old vaccinated specimens, and summer budding can be used provided that the grafted plants provide a comfortable wintering, since early frosts characteristic of the Bashkir Urals lead to the death of green and not yet lignified shoots. The method of aerial roots can be considered acceptable and promising for the vegetative propagation of lilacs varieties.

Abstract:

The proportional allocation of plant total resources for growth, reproduction, vegetative propagation, and the balance between them were examined in Arum italicum. A minimum threshold dry mass (2.5 g) was found in this species before reproduction could occur, but above 10 g of dry mass, all individuals in a sample of 151 produced at least one inflorescence. Resource allocation for vegetative growth, sexual reproduction, and vegetative propagation significantly increased as dry mass of the plant increased. Increases in plant size resulted in increased proportional allocation to sexual reproduction, and relative decreases in both vegetative growth and vegetative propagation. Mass ratios between sexual reproductive structures and new tuber, and between sexual reproductive structures and organs of clonal growth increased with plant size. Allocation of resources to reproduction occurred at the expense of vegetative growth. In reproductive plants, the cost of reproduction, measured as relative reduction in vegetative growth was approximately 24% and was estimated by comparing growth in nonreproductive plants. Key words: Arum italicum, Araceae, cost of reproduction, reproductive allocation, vegetative growth, vegetative propagation.

Abstract:

Vegetative propagation is an important method of reproduction and rejuvenation in horticulture and forestry plants with a long lifespan. Although substantial juvenile clones have been obtained through the vegetative propagation of ornamental plants, the molecular factors that regulate rejuvenation during vegetative propagation are largely unknown. Here, root sprouting and root cutting of Robinia pseudoacacia were used as two vegetative propagation methods. From two consecutive years of transcriptome data from rejuvenated seedlings and mature trees, one gene module and one miRNA module were found to be specifically associated with rejuvenation during vegetative propagation through weighted gene co-expression network analysis (WGCNA). In the gene module, a transcription factor-encoding gene showed high expression during vegetative propagation, and it was subsequently named RpTOE1 through homology analysis. Heterologous overexpression of RpTOE1 in wild-type Arabidopsis and toe1 toe2 double mutants prolonged the juvenile phase. The qRT-PCR results predicted RpFT to be a downstream gene that was regulated by RpTOE1. Further investigation of the protein-DNA interactions using yeast one-hybrid, electrophoretic mobility shift, and dual luciferase reporter assays confirmed that RpTOE1 negatively regulated RpFT by binding directly to the TOE binding site (TBS)-like motif on its promoter. On the basis of these results, we showed that the high expression of RpTOE1 during vegetative propagation and its inhibition of RpFT played a key role in the phase reversal of R. pseudoacacia.

Abstract:

SynopsisThe effect of photosynthetic photon flux density (PPFD), water, temperature and nutrition on frond emergence, vegetative frond production, fertile frond production, vegetative propagation and dormancy is examined. Ostrich fern plants will not break winter dormancy until they have received a minimum amount of cold exposure below a base temperature which is above 5.8°C and may be as high as 20°C. After the plants have received their chilling requirement, vegetative frond emergence does not occur until temperatures at or above ca. 9.3°C are reached. Percent germination and rate of emergence increases up to ca. 24°C. Photosynthetic photon flux density, water availability and mineral nutrition can affect both vegetative and fertile frond production but water availability appears to be the most critical. A mild water stress of −0.15MPa can have significant effects on water status and gas exchange in fronds. Sporophyte plants for field production have been produced vegetatively from detached meristems occurring naturally on the rhizomes, and through fertilization of axenic gametophytes.

Abstract:

Most of fruit species are propagated by vegetative methods such as budding, grafting, cutting, suckering, layering etc. to avoid heterozygocity. Carob trees (Ceratonia siliqua L.) are of highly economical value and are among the most difficult to propagate fruit species. In the study, air-layering propagation method was investigated first time to compare wild and cultivated (‘Sisam’) carob types. In the experiment, one year old carob limbs were air-layered on coco peat medium by wrapping with aluminum foil and polyethylene film. Initial roots were observed after three months of treatment and the well rooted limbs were cut-off after six months of treatment. Root length, diameter, and the number of roots were recorded on treated shoots and the rooted shoots were transferred into soil. As a result, it has been found that air-layering is successful in carob. This method is more labor intensive and thus it is recommend the method only for genetically important carob types propagation.

Abstract:

Abstract Greenwood cuttings from greenhouse-produced tamarack seedlings and 3- to 10-year-old tamarack wildlings transplanted from natural stands in north-western Ontario were rooted under mist in peat-vermiculite. Eighty-five percent of cuttings from seedlings rooted; treatment with indolebutyric acid increased number of roots per cutting, but not rooting percent. At 6 weeks after planting, rooting of cuttings from wildlings averaged 66%, and at 12 weeks, 91%. Twelve-week rooting percent of cuttings from individual ortets ranged from 12 to 100, but cuttings from the majority of ortets exhibited 100% rooting. Nearly all rooted cuttings survived overwintering outdoors and initiated normal shoot growth after forcing in mid-winter. The described propagation system is recommended for production of container stock for tamarack plantations. North. J. Appl. For. 3:91-93, Sept. 1986.

Abstract:

The ontological changes in cyanobacterial ultrastructure, including akinete germination and heterocyst differentiation, during the propagation of mature sporophytes from Azolla microphylla sporocarps were examined using transmission electron microscopy. Rehydrated Azolla megasporocarps contained cyanobacterial akinetes having a multilayered envelope and large amounts of cyanophycin and glycogen. Concomitant with the initial stages of sporocarp germination was the formation of vegetative cyanobacterial cells via germination of akinetes. Once fern plantlets had four visible leaves, vegetative cyanobacterial cells had begun to differentiate into heterocysts in the cavity of the oldest leaf; this timing was very similar to that observed in vegetatively reproducing sporophytes. Ultrastructural characteristics of vegetative cyanobacterial cells present at the apical meristem of plants generated either by sporocarp germination or vegetative propagation were indistinguishable. These cells remained in an undifferentiated state regardless of plant age. However, as in vegetatively propagated plants, the cyanobacterial population and ultrastructural characteristics of cells in older leaf cavities were exceedingly diverse. This is the first report that groups of pleomorphic eubacteria are contained beneath the indusium of rehydrated Azolla microphylla megasporocarps. Concomitant with the early morphological changes of germination of Azolla megasporocarps and endosymbiotic akinetes was the initiation of cell division by the eubacteria. Key words: akinetes, Azolla–Anabaena, endosymbionts, sporocarp.

Abstract:

Horticulture is an important part of agriculture with many important crops being vegetatively propagated. The objectives of this work were to discuss some of the most important characteristics of vegetatively propagated crops and the breeding strategies to develop and propagate new cultivars. Vegetative propagation enables to fix favorable combinations of important traits, very specific chemical compositions, superior genetic variance interactions and high levels of heterozygosity. Breeding new cultivars involve few possibilities of genetic recombination by sexual reproduction and many generations of selection and vegetative propagation. Marker assisted selection should be useful for genotyping and selecting complementary parents for crossing and for identifying superior genotypes at early stages of selection. The tissue culture technique enables to get disease free stock plants and to maximize its multiplication rate, having an important role in yield and quality of these crops.

Abstract:

TRAINING ON VEGETATIVE PROPAGATION TECHNIQUES OF ORNAMENTAL PLANTS FOR PKK WOMEN IN BOKOR VILLAGE, TUMPANG, MALANG REGENCY. The Covid-19 pandemic that has hit the world in the last 2 years has harmed all sectors of human life. The Indonesian government issued a policy to reduce the activity and mobility of people outside the house to reduce the rate of transmission of the virus. This policy has hurt the people's economy. Activities that are only in the house environment can increase the potential for stress in the community. One solution to overcome the problems mentioned above is to cultivate ornamental plants in the yard of the house. The trend of ornamental plant cultivation has an impact on increasing the number of requests and prices of ornamental plants and it is directly related to the strengthening of the bargaining position of ornamental plant farming. Activities carried out include observation, training, practice of ornamental plant propagation and assistance, and evaluation. The vegetative propagation techniques used were leaf cuttings, stem cuttings, seedling separation, and a demonstration of grafting activities, which were carried out on 9 of ornamental plant species, namely sansevieria, zamioculcas, little hogweed, aglaonema, iris, carwx morrowii, spider ivy, dracaena, and codiaeum. The results of the activity showed that partner’s knowledge and skills in the vegetative propagation of ornamental plants increased by 19%. The participants were able to reproduce ornamental plants vegetatively well. The percentage of success in growing plants from partner propagation is 71.4-100%.

Abstract:

The effects of vegetative propagation on plant performance in the desert tulip Tulipa systola were studied experimentally. A differentiation was made between immediate effects (possible tradeoffs between vegetative propagation and seed production) and ultimate costs or benefits (reduction in overall plant growth and biomass production efficiency per unit leaf mass, and within-clone competition). The results of a garden experiment with either single bulbs (single-ramet genets) and clusters of bulbs (multi-ramet genets) of the same total size, exposed to three levels of irrigation, did not show immediate nor ultimate disadvantages of vegetative propagation in terms of seed production or plant growth parameters. Competition between ramets of the same genet seemed to occur at low soil moisture availability, but it did not cause a disadvantage to multi-ramet genets relative to single-ramet genets. Vegetative propagation as a safeguard against complete genet consumption by porcupines is also discussed. Finally, the hypothesis is proposed that, in stead of influencing sexual reproduction negatively, vegetative propagation may in fact increase lifetime seed production, because multi-ramet genets may produce more fruits than single-ramet genets having the same level of genet growth.

Abstract:

The genus Allium L. consists of about 500 species in the Northern hemisphere and includes a large number of useful plants. The highly variable underground organs of Allium species - rhizomes and bulbs - have the function of storing food and moisture in severe environmental conditions. Their other very important function - vegetative reproduction and propagation - increases the chances of survival and supports the genetic stability of natural populations. Among about 40 species studied, 5 types of vegetative reproduction and propagation are distinguishable. The formation of apical buds, daughter bulblets, stolons and apomictic bulblets in the inflorescense have been observed. There is possibly some connection between vegetative propagation, morphological type and life cycle. The process of evolution within the genus and the migration of species to arid conditions lead possibly to the appearance in phylogenesis of prevalence of seminal reproduction over vegetative propagation.

Currently, propagation of tea plant using one leaf is a common way to fulfil the need of plant material in large quantity also short in time. One of requirements in assembling new superior tea clone is the easy of clone to be propagated vegetatively. Clone which is easy to propagate in vegetative way is apt more by the gardeners. One required test on tea plant breeding process is vegetative propagation test of new superior clone candidates. This research aimed to determine variability of growth ability and several growth components of cutting seed in vegetative propagation. The research was carried out in Breeding Nursery, Experimental Field of Tea and Cinchona Research Institute Gambung. The trial was set in Randomized Block Design (RBD) with 19 clones as the treatment which was repeated three times, each treatment consisted of 52 cutting seeds. The result showed that almost all genetic variability of characters observed were included to wide category, except for root length and root dry weight characters. Phenotypic variability showed that nearly all characters observed were comprised to wide category, except root dry weight.

Abstract:

ABSTRACT The production of healthy pineapple seedlings for commercial plantations has been one of the main limiting factors of the species, and the search for improvements to meet this demand has been constant. Therefore, the present study aimed to compare different propagation strategies (natural tillering, stem sectioning, and micropropagation) in three commercial cultivars 'BRS Imperial', 'Pérola', and Gold 'MD-2' of pineapple. Three methods of vegetative propagation were evaluated: conventional, stem sectioning, and micropropagation. The evaluations consisted of the number of seedlings produced by each method and the period for their development until planting in the field. According to the conventional propagation technique results, the young seedling type in the cultivar 'Pérola' was more abundant. In the propagation by sectioning the stem, the 'BRS Imperial' cultivar presented the highest number of seedlings. Regarding the micropropagation technique, the highest production of shoots was observed in the third subculture for all cultivars, especially for ‘BRS Imperial’, which presented the highest total number of shoots in all subcultures. It was concluded that the micropropagation technique proved efficient in producing uniform seedlings on a large scale, in addition to having an advantage in the greater number of seedlings produced compared to the other methods studied.

Abstract:

The expression of defensive compounds derived from secondary metabolism in plants of Eucalyptus globulus Labill, and the persistence of these in vegetative propagation was evaluated by gas chromatography with flame ionization (GC-FID) and mass spectrometry (MS). The plants were induced by attack from the insect Ctenarytaina eucalypti (“blue gum psyllid”) and by mechanical damage. Defense responses were activated in plants for the different types of tested induction. We identified four defensive compounds present in the leaves of plants induced in entomological form (β-terpineol, aromadendrene, caryophyllene-oxide and eremophilene); all remained in the vegetative propagation. After mechanical induction, we identified three compounds (β-terpineol, aromadendrene and ledol), of which ledol and aromadendrene persisted in the vegetative propagation. Virtually all the compounds detected, in addition to persisting in the vegetative propagation, showed specificity for the induction type, whether entomological or mechanical, except for aromadendrene, which was expressed in both types of induction.
