Abstract:
Abstract The influence of bottom heat, rooting medium, type of cutting (i.e. terminal vs. subterminal), and commercial auxin formulations on greenhouse propagation of firebush (Hamelia patens Jacq.) by leafy stem cuttings during winter was investigated. Without bottom heat, mid-day rooting medium temperature averaged about 22 ± 3°C (72 ± 5°F). Percent rooting of auxin-treated cuttings without bottom heat was 50% and mean length of the longest root and visual rating scores of root development were low. Maintaining the rooting medium at 29–39°C (85–10 1°F) increased percent rooting for auxin-treated cuttings to 96–100% and increased root length and visual rating scores several-fold. Rooting percentage, root length, and visual rating scores were consistently high in perlite and low in peat moss. Terminal stem-tip cuttings and subterminal stem segment cuttings with basal stem diameters of 3–5 mm (0.13–0.20 in) rooted slightly better than subterminal stem segment cuttings which had basal stem diameters of 6–8 mm (0.25–0.32 in.). Terminal stem-tip cuttings not treated with auxin but with bottom heat had rooting percentages of 81–86%. Treatment of terminal stem-tip cuttings with Rootone F or Wood's Rooting Compound (1:20 or 1:5 dilution) generally resulted in rooting percentages above 90%. Some of the auxin treatments also resulted in increased root length and visual rating scores. Despite these differences, none of the plants grown from auxin-treated cuttings, were distinguishable from plants grown from nontreated cuttings two months after the rooting period. Of the variables studied, bottom heat had the most dramatic effect on rooting of stem cuttings during winter months.

Abstract:
Studies were conducted to investigate the effects of season (timing), IBA application, genotype, crown position, type of cutting (straight vs. heel), cutting length, and stock plant age upon adventitious rooting of stem cuttings of eastern redcedar (Juniperus virginiana L.). Genotype had a strong influence on percent rooting, root count, and root length of 4-year-old trees. With trees of this age, percent rooting was maximized (87%) with hardwood cuttings taken in January and treated with 5000 ppm IBA. Crown position from which cuttings were collected did not influence rooting. Straight cuttings, with or without a light wound, rooted at a significantly higher percentage (78%) than heel cuttings (52%). With 30-year-old trees, cuttings from the lower third of the crown rooted at a significantly higher percentage (67%) than cuttings from the middle third (43%). Better rooting was obtained with straight (68%) than heel (47%) cuttings. Cutting length affected rooting, with root count and length highest in longer cuttings. Increased tree age reduced rooting, although cuttings from 40-year-old trees retained substantial rooting capacity. Chemical name used: 1 H-indole-3-butyric acid (IBA).

Abstract:
The influence of the date of cutting collection and cutting position in the crown on rooting quality was evaluated in cuttings taken from seven-year ortets. The evaluation of various dates of cutting collection in spring demonstrated a possibility of successful propagation by cuttings during a relatively long period from full bud dormancy to flushing onset. The relationship between the development of aboveground parts (flushing, shoot and bud formation) and rooting quality was not established. The exposure of cuttings in the crown of parent tree with respect to the cardinal points did not influence rooting percentage and quality. A somewhat higher rooting ability was observed in cuttings from lower parts of the crown in comparison with cuttings taken from the highest whorls. Differences were more perceivable in generally weak-rooting clones. The comparison of rooting quality in cuttings from seven- and eight-year mother plantations with cuttings from a sixteen-year mother plantation confirmed that not only the rooting of cuttings collected from older mother plantations is weaker but also their growth is slower and their plagiotropic growth continues for a longer time.

Abstract:
The rooting ability of GF677 peach rootstock by hardwood (H), semihardwood (SH), and softwood (S) stem cuttings collected January, February, May, and November, treated with various IBA concentrations—0, 500, 1000, 2000, and 3000 ppm—was studied. H cuttings collected in January and treated with 2000 ppm IBA caused significant increase in rooting (62%–5%). In addition, the SH cuttings prepared February and treated with 1000 or 2000 ppm IBA gave 42.5%. The May experiment resulted in low rooting percentage where H cuttings treated with 500 ppm IBA gave 10% rooting. In October, SH cuttings with 1000 or 3000 ppm IBA gave the highest rooting percentage (60%), while in November 90% rooting was obtained in H cuttings treated with 3000 ppm. Regardless of type of cutting, IBA at 1000, 2000, or 3000 ppm was better for rooting the GF677 than at 500 ppm. However, irrespective of IBA concentration, H and SH cuttings gave significantly high rooting percentages. On the other hand, best rooting was obtained when the stem cuttings of GF677 (regardless of wood type) were collected in November. Wounding base of the cutting of GF677 improved rooting ability.

Abstract:
Hardwood cuttings of kinnikinnick (Arctostaphylos uva-ursi `Massachusetts') were inoculated with three different types of inoculum of mycorrhizal fungi to determine whether addition of mycorrhizal inoculum into the rooting substrate during cutting propagation increases rooting or root growth, or alters the time for rooting. Cuttings, treated or untreated with rooting hormone prior to sticking into the rooting substrate, were inoculated with either inoculum of an arbuscular mycorrhizal fungus (AMF), hyphal inoculum of an arbutoid mycorrhizal fungus (E), or inoculum consisting of colonized root fragments of kinnikinnick (R). Cuttings were placed under mist in a greenhouse with no bottom heat and harvested 35, 56, and 84 days after sticking. Using AMF inoculum in the rooting substrate did not enhance rooting of cuttings, while adding the R or E inoculum to the rooting substrate increased root initiation compared to non-inoculated cuttings. Cuttings inoculated with either the R or E inoculum had greater root initiation than non-inoculated cuttings 56 and 84 days after sticking. When treated with rooting hormone, cuttings inoculated with the E or R inoculum had longer roots and a greater root biomass than non-inoculated cuttings. Mycorrhizal colonization of roots was similar or greater when cuttings were inoculated with the E inoculum than with the R inoculum and application of rooting hormone generally increased root colonization. The use of inoculum composed of root fragments from kinnikinnick during cutting propagation does not appear to be more beneficial than use of hyphal inoculum from a known arbutoid mycorrhizal fungus.

Abstract:
Pteroceltis tatarinowii Maxim, the only species of the genus Pteroceltis (family Ulmaceae), is an endemic rare tree species in China. This study was performed to explore vegetative propagation techniques for P. tatarinowii using stem cuttings. First, the effects of exogenous indole-3-butyric acid (IBA) and cutting positions on rooting performance were investigated to screen the appropriate exogenous auxin treatment and to determine the proper cuttings type. The results showed that the control cuttings pretreated with no exogenous IBA, irrespective of whether the stem cuttings were terminal, middle, or basal, rooted in a manner significantly inferior to that of cuttings pretreated with IBA. Their rooting percentage was less than 50%. Among the IBA-treated cuttings, the middle cuttings pretreated with 1000 mg·L−1 IBA rooted best, with the shortest number of days until rooting emergence (20 days), the highest rooting percentage (84.0%), the lowest mortality rate (4.0%), the greatest root number (average of 6.7 per cutting), and the longest roots per cutting (44.4 cm per cutting). Terminal cuttings pretreated with 1000 mg·L−1 IBA acquired satisfactory rooting traits and had the same shortest rooting duration (20 days) and the following parameters: rooting, 70.7%; mortality, 10.7%; average roots per cutting, 5.2; and longest root, 29.1 cm. To further determine the optimum cutting propagation time for this plant, a second experiment was performed and the cuttings were collected beginning in early June, when the growth of the current season was feasible for harvesting cuttings. Stem cuttings collected in late June and middle July had significantly higher rooting percentages (≥80%) compared with those collected in early June (66.7%). The other three rooting parameters were not significantly affected by the collection date. However, according to the overall rooting traits, the cuttings collected in both late June and middle July remarkably outperformed those collected in early June regarding the number of roots and the total root length per cutting. The initial nutrient reserves in the cuttings were also determined. A significant difference in the soluble carbohydrate level was found among collection times, but the nitrogen level in the cuttings was similar. The study revealed that stem cutting propagation of P. tatarinowii was achievable, and it was best achieved with cuttings collected from the terminal and middle positions of the branches of the current season from late June to middle July and treated with 1000 mg·L−1 IBA using the quick dip method.

Abstract:
Vegetative propagation by cuttings is a very popular method. However, blueberry propagation using cuttings is still a main factor limiting its expansion because its results can vary according to the blueberry cultivar and environmental factors. This study aimed to evaluate the rooting abilities of hardwood cuttings for six blueberry cultivars (O’Neal, Misty, Diana, Biloxi, Bluebeauty, and Coville) using three different exogenous indole-butyric acid (IBA) concentrations (1000, 2000, and 3000 ppm), and to determine if the cutting position (basal, central, apical) affects rooting performance. A control treatment (0 ppm IBA) was also performed. After 90 days of each treatment, rooting percentage, average root length, and average root number per cutting were assessed and used to calculate rooting index, which is a measure of rooting ability. The rooting percentages of hardwood cuttings differed largely among cultivars and were highest for ‘Bluebeauty’ (68.55%), followed by ‘Biloxi’ (68.01%). The rooting index values of these two cultivars (33.59 and 35.18, respectively) were significantly higher than those of the other four cultivars. The rooting response of blueberry hardwood cuttings to IBA concentrations was quadratic, and 1000 and 2000 ppm IBA were sufficient to express the maximum rooting percentage in most cultivars. The rooting abilities of basal, central, and apical cuttings were similar with treatments with high IBA concentrations. The effects of the cultivar, IBA concentration, and interaction between them on rooting percentage, average root length, and average root number were significant; however, the effects of the cutting position on the rooting percentage and average root length were not. This suggested that the rooting abilities of blueberry hardwood cuttings were significantly influenced by the cultivar and IBA concentration rather than by the cutting position.

Abstract:
In this study, the effect of concentration of indole-3-butyric acid (IBA) (powder dip), cutting type as well as the time of taking cuttings on the rooting of softwood cuttings of cornelian cherry was examined. Four types of cuttings were used: basal cuttings, terminal cuttings, basal cuttings with 2-year-old wood and terminal cuttings with 2-year-old wood. The obtained results showed that IBA concentration, cutting type and time of collecting have significant effect on rooting. The best results were obtained using 1% IBA and cuttings collected in the second term (in mid-July) had a higher rooting percentage. Terminal cuttings treated with 1% IBA (powder dip) should be used for optimum results. In that case the rooting percentage was very high (over 90%) in both terms of cuttings collection.

Abstract:
Root development of stem cuttings of Silver Germander (Teucrium fruticans) was investigated in relation to cutting type and indole-3-butyric acid (IBA) treatment. Terminal cuttings of a clone grown in Sicily were trimmed to three types: terminal cuttings with apex (TWA), terminal cuttings without apex (TWOA) or sub-terminal cuttings (ST). To verify the cutting response to exogenous auxin, cuttings were dipped to a 2.0 cm depth in a 0.5% indole-3-butyric acid solution for 0, 5 or 7 minutes. Overall percent survival was 97 to 98%. Rooting percent, root number and root length were affected by cutting type and indole-3-butyric acid treatment. In general, TWA cuttings demonstrated a higher capacity to form roots than cuttings without apex (TWOA and ST cuttings). In absence of indole-3-butyric acid treatment, TWA and ST cuttings gave higher rooting percentages than TWOA cuttings. Exposing cuttings to indole-3-butyric acid improved percent rooting, number of roots per cutting and root length. The best results in terms of rooting percentage and root number per cuttings were obtained with TWA cuttings in combination with 7 min indole-3-butyric acid basal dip. However, cuttings taken farther down the stem, such as sub-terminal cuttings gave satisfactory rooting performance as well. We suggest that the use of all cutting types tested associated to indole-3-butyric acid basal dip for 5 or 7 min may be beneficial to propagators wishing to produce T. fruticans rooted cuttings with well-developed root system.

Abstract:
Clonal and cutting stem morphology variations in rooting ability were simultaneously examined in Allanblackia floribunda Oliv. using leafy stem cuttings in two experiments. The hypothesis tested is that clonal variation in rooting percentage is due to variation in cutting morphology. Each of the four replicate blocks used per experiment consisted of 18 treatments from two crossed factors, diameter or length × clone, making a total of n = 216 cuttings (3 cutting lengths (3, 4, and 5 cm) or diameters (2, 3, and 4 mm) × 6 stumps (clones) × 12 cuttings, as each experimental unit consisted of 12 cuttings). The cuttings were used for rooting in nonmist propagators. No clone × cutting diameter and clone × cutting length interactions (P = 0.293 and 0.513, respectively) on rooting percentage were found at the end of the study. Highly significant and significant clonal variations in rooting percentage were noted throughout the experiments. Results from this study reject the hypothesis being tested. Finally, further work should be done on the effects of physiological status of the cuttings and clonal variation in this species.

ENGLISH ABSTRACT: Buchu (Agathosma betulina and A. crenulata) are grown commercially as an aromatic crop and are endemic to the Western Cape of South Africa. Poor rooting of cuttings have limited the development of superior clones. Under standard mist bed conditions terminal, sub-terminal or basal stem cuttings were taken from March to August. When not treated with an auxin, rooting percentages of between 20 and 25 were obtained. Rooting percentages increased to between 40 and 45 after treatment with 500-1000 ppm indolebutyric acid (lBA). Substituting lBA with naphthaleneacetic acid (NAA) did not improve rooting. There was a tendency for cuttings with fewer than four leaf pairs to give lower rooting percentages. Plants of Agathosma betulina x A. crenulata, grown in Paarl, and A. betulina, grown in Piketberg, were used as source plants for making cuttings. Paarl plants were shaded with 80 percent shade and Piketberg plants with 60 or 80 percent shade respectively from February to October 2002. Plants in full sun served as a control. Plants were pruned back initially in February and then two months before samples were taken in March, June, August and October at both locations. New shoots were used as cuttings. Terminal cuttings for rooting and for carbohydrate analyses were collected on four different dates (March, June, August and October). Cuttings were treated with 500 ppm indolebuteric acid (lBA) and placed in misting beds with bottom heating (18-25°C) for a period of three months. Shading reduced rooting of cuttings from the Paarl plants. However, it did not significantly increase rooting of cuttings taken from Piketberg plants. Rooting percentage was the highest in August (43%) for cuttings from sun grown plants in Paarl. No consistent relationship between, respectively, dry mass or carbohydrate content of cuttings and rooting could be established. Terminal current years' growth, taken from Agathosma crenulata x A. betulina (hybrid) softwood cuttings, collected in January 2002, were extracted with methanol and fractioned by thin layer chromatography (Silica gel) in isopropanol: acetic acid: water (4: 1:1 v/v). The chromatographs were divided in ten fractions and were bio-assayed for a rooting co-factor with the mung bean rooting test. Extracts from buchu cuttings showed significant activity at the Rf values of co-factor 3. Co-factors 1,2 and 4 do not seem to be present in significant quantities. However, co-factors with Rf values different from previous reported values were present in significant quantities. No inhibition was found in buchu. In fact, all Rf values stimulated rooting.
AFRIKAANSE OPSOMMING: Boegoe (Agathosma betulina x A. crenulata) word kommersieël verbon as 'n aromatiese gewas en is endemies tot die Wes-Kaap. Die ontwikelling van superieure klonale materiaal word beperk deur swakbeworteling. Terminale, sub-terminale en basale steggies is gesnyonder standaard misbed toestande van Maart tot Augustus. Beworteling was tussen 20 en 25 persent as geen ouksien gebruik word nie. As indolebottersuur (IBS) gebruik word tussen 500-1000 dpm, verhoog die bewortelingspersentasie tot tussen 40 en 45 persent. Die gebruik van naftaleen asynsuur (NAS) in plaas van IBS het nie beworteling verbeter nie. Daar was a tendens dat steggies wat minder as vier blaarpare gehad het 'n verlaging in bewortelingspersentasies gehad het. Plante van Paarl, A. betulina x A. crenulata, en Piketberg, A. betulina, is gebruik as plantmateriaal vir steggies. Plante in die Paarl was onder 80 persent skadu geplaas en plante in Piketberg onder 60 en 80 persent skadu van Februarie tot Oktober 2002. Plante in vol son was as 'n kontrole gebruik. Plante was eers in Februarie teruggesny en dan weer twee mande voor monsters geneem is. Die monsters is in Maart, Junie, Augustus en Oktober geneem in beide liggings. Terminale steggies is vier keer ingesamel (Maart, Junie, Augustus en Oktober) vir beworteling en koolhidraat analises. Die steggies is met 500 dpm IBS behandel. Daarna is die steggies vir drie maande in die misbed geplaas met bodem-verhitting (18- 25°C). Dit is gevind dat die gebruik van skadu die beworteling in Paarl verminder het alhoewel die beworteling in Piketberg nie beduidend beinvloed is nie. Die hoogste bewortelingspresentasies is waargeneem in Augustus (43%) in Paarl van plante wat in vol son was. Geen verband tussen onderskeidelik die droe massa of koolhidraat inhoud en beworteling kon gevind word nie. Terminale steggies van dieselfte jaar se groei van Agathosma betulina x A. crenulata (hibried) is in Januarie 2002 ingesamel. Die materiaal is geëkstraheer en gefraksioneer deur dunlaag kromatografie in isopropanol: asynsuur: water (4: 1:1 v/v). Die kromograaf is in 10 fraksies verdeel. Die fraksies was bioassaieer VIr beworteling ko-faktore met die mungboontjie bewortelingstoets. Die ekstrakte van boegoe het beduidende aktiwiteit by die Rf waardes van ko-faktor 3 getoon. Ko-faktore 1, 2 en 4 is nie in groot genoeg hoeveelhede waargeneem nie. Ko-faktore, wat nie voorheen gevind is nie, is waargeneem in beduidende hoeveelhede. Geen inhibitors is in boegoe gevind nie en al die getoetste ko-faktore het beworteling gestimuleer.

Abstract:
Mortonia scabrella can be successfully propagated by stem -tip cuttings during May to September. Better rooting seems to occur during the less stressful months of May and September than in mid-summer. A wide range of rooting response occurs between different clones; the best will root in the range of 70-80%, which should be acceptable in a commercial propagation situation. In one cycle of selection in which the best 3 out of 16 clones were selected for a repeat study, average rooting success increased from 6% to 33 %. Apparently genetic differences for rooting potential occur. Further selection from larger populations, and/or breeding for this trait should result in cutting propagation becoming relatively easy for this species.

Abstract:
The principle hypothesis of this thesis is that hypoxia, in agar-based media, compromises rooting in vitro. From a practical point of view this is important because most plant tissue culture activities require the material to be successfully acclimatised in a nursery environment. Compromised rooting often results in excessive losses at this stage which are costly and inconvenient. In addition, many plants with commercial and/or scientific interest remain unavailable as they are not able to be rooted and acclimatised reliably. The use of agar as a rooting medium has limited the capacity of plant tissue culture to clonally propagate many plants. The thesis begins by demonstrating how poorly some plants respond to agar rooting media. Juvenile Chamelaucium hybrid microcuttings were pulsed with IBA 40 mcg M and then placed for 3 weeks on either M1 (1/2 MS) or aerated in vitro soil-less substrate (IVS) (Chapter 2). IVS had 42-82% rooting at the end of Stage 3 compared with 0-1% in agar. Shoot survival for IVS-rooted microcuttings was significantly greater than M1-rooted shoots. Pulsed shoots placed in IVS showed root primordia after 7 days. In contrast, shoots placed in agar showed no root primordia after 21 days and formed callus but did not root when subsequently placed in IVS for a further 4 weeks. The agar medium almost totally and permanently inhibited the capacity of competent shoots to form root primordia and roots. The effectiveness of different types of aerated and non-aerated media, including IVS, were tested to validate the hypothesis (Chapter 3). Microcuttings from shoot cultures of two Australian plants Grevillea thelemanniana and Verticordia plumosa x Chamelaucium uncinatum were pulsed for 7 days on a high auxin (40 mcg M IBA), agar-solidified medium in the dark. Rooting of the microcuttings was then compared on five experimental substrates: a) standard agar M1 medium (1/2 MS, no hormones, 8 g agar L-1), b) porous-agar medium (1/2 MS, no hormones, 30 g agar L-1, solidified then blended to provide aeration), c) white sand wet with liquid M1, d) white sand with M1 medium containing agar, and e) IVS. A separate experiment involved flushing the IVS soil profile with low or normal oxygen. Low and variable rooting percentages were recorded on the controls on M1 medium. Root induction and average total root length per microcutting at final harvest were significantly higher using the porous media including IVS, blended agar or white sand. The M1 medium and the addition of M1 medium to sand suppressed the percentage rooting and elongation. Flushing the IVS rooting medium with low oxygen also suppressed rooting. The experiments showed that increasing the air-filled porosity of the rooting medium has a positive effect on rooting and this is most likely due to the increased oxygen at the base of the microcutting. The role of ethylene, and the sugar and nutrients in M1 were not investigated. The efficacy of the IVS protocol on a range of Australian herbaceous and woody species was investigated to determine whether the observed benefits were generic or plant specific (Chapter 4). Improved rooting in IVS compared to agar was shown for 28 Australian species and genotypes from the families Liliaceae, Haemodoraceae, Myrtaceae, Thymelaeaceae, Proteaceae, Goodeniaceae and Rutaceae. Twenty-seven of the 28 species rooted in IVS medium at equal or better rates than in M1. In three cases - Actinodium cunninghamii, one of the Pimelea physodes genotypes and one of the Eriostemon australasius genotypes - shoots did not root in M1 but showed good root development in IVS medium. With few exceptions average root length and number in microcuttings rooted in IVS was superior to those in agar medium. To further test the resilience of the hypothesis, it was tested on nodal microcuttings of lentil which are recalcitrant to root in vitro (Chapter 5). The veracity of a published conclusion that inverted lentil microcuttings (with their base in the air) root better because of their altered polarity was also examined. It was found that, as is the case for many species, roots initiated and grew only at the proximal end of the microcutting regardless of its orientation. When the proximal end was in agar (a hypoxic environment) the rooting percentage was low (9-25%) even when the orientation of the microcutting was altered by inverting the culture tube. In contrast, when the proximal end of the microcutting was in an aerobic environment (from the shoot being placed upside down in agar medium or placed normally or upside down in an aerated medium) rooting percentages were higher (62-100%). Given that Stage 2 microcuttings are prepared with the objective to root and acclimatise them to nursery conditions, the duration of this activity becomes important as it can impact on plant quality and costs. The pulsing protocol and the length of time that Stage 3 cultures remain in the culture room during the rooting phase is a component of the unit cost of production of each rooted microcutting. Initially a 7-day IBA pulse was used after which the pulsed microcuttings were transferred to IVS to root. Chapter 6 shows that the pulsing period can be shortened to one day or replaced with a single auxin dip while still achieving high rooting percentages and maintaining plant quality. These materials handling improvements go some way to realising the logistical benefits of ex vitro rooting but without compromising the positive influences of hygiene and a stable environment of the in vitro environment.

African, Podocarpus falcatus, Syzigium cordatum and introduced species, i.e. Acacia mearnsii, A. melanoxylon, Eucalyptus grandis and Melia azedarach were studied and improved at the Cape Technikon nursery from May 1994 to June 1998. These tree species are considered problematic since the indigenous species produce unwanted fruits in urban areas which attract frugivores, while the introduced species are a threat to indigenous vegetation and natural habitats, though they are of great commercial value. The progress in mutation breeding of sexual sterility in most of the problematic species created a need to propagate them vegetatively. Without cloning of seedless species, their beauty and economic value to South Africa will be lost, as the indigenous species will be neglected, while invasive species will continue to threaten the natural habitat of indigenous species. Experiments were conducted to test age, type and length of cuttings, environmental factors, growth season, hormone application, various treatments and rooting media for each of these species. This study showed that relatively few publications relevant to the vegetative propagation of indigenous tree species are available. However, some introduced species, e.g. Eucalyptus grandis, are propagated successfully for commercial forestry purposes. Ficus sur and Syzicium cordatum showed the highest rooting success, i.e. 85-90%, followed by Olea europaea subsp. africana (75-80%), and Podocarpus falcatus (60%). The introduced species showed no rooting success, however, callusing in Eucalyptus grandis (35-61%), and Melia azedarach (50%), and survival rates in Acacia mearnsii (10%) and A. melanoxylon (20%) were achieved. Treatments, i.e. etiolation, placing plants under stress, sealing basal stems of cuttings, and fungicide treatments all showed positive results in promoting callusing success. The study showed that rooting success in individual species are directly related to the growth stage of parent plants as well as the season during which the cuttings were taken. With progress towards successful vegetative propagation of sterile problem plant species, propagators and horticulturists can in future apply these improved techniques. These plants will then continue to supply timber, fire wood and improve aesthetics in the South African urban environment.

The rose is the flower most traded in the world, and Cearà has been outstanding in their production in greenhouses. However, virtually all the production techniques employed by growers are based only on field observations, without any scientific basis. The objective of this study was evaluate the influence of substrate and added with nutrient solution in the rooting of cuttings roses, variety Carola, propagated in plastic trays by the method of cutting (or striking), and evaluate their productivity in greenhouses. The experiment was conducted in the municipality of SÃo Benedito - CE, in the company CeaRosa Com Exp Imp. e Prod. Flowers Ltda. in its early seedling production, and in the TecFlores - School of Floriculture of the State Government of Cearà in its early planting in the greenhouse. Were also evaluated six substrates (100% sand, 100% dry coconut fiber, 50% sand + 50% dry coconut fiber, 75% dry coconut fiber + 25% sand, 25% dry coconut fiber + 75% sand and 25% husk rice + 75% dry coconut fiber). The experimental design was factorial analysis with two factors, and the parameters evaluated were added with nutrient solution and the six substrates. At the stage of seedling production was evaluated the percentage of catches of seedlings, root length, seedling dry weight and content of macro and micronutrients present in seedlings. In the production phase and development in the greenhouse, were assessed the number of sprouts emitted by plants and the levels of macro and micronutrients of the leaf tissue of plants. The added with nutrient solution was not affect the percentage of catches of the seedlings, regardless of the substrate, but was affect the root length and dry weight of seedlings. The productivity of the rose plants was not affected by the substrate or by added with nutrient solution during the rooting process.
A rosa à a flor mais comercializada no mundo, e o Cearà vem se destacando na sua produÃÃo em estufas. No entanto, praticamente todas as tÃcnicas de produÃÃo empregadas pelos produtores baseiam-se apenas em observaÃÃes de campo, sem qualquer embasamento cientÃfico. O objetivo deste trabalho foi avaliar a influÃncia de diferentes substratos e do enriquecimento destes atravÃs de imersÃo em soluÃÃo nutritiva no enraizamento de mudas de roseira, variedade Carola, propagadas em bandejas plÃsticas pelo mÃtodo de estaquia, bem como avaliar sua produtividade sob cultivo protegido. O experimento foi conduzido no municÃpio de SÃo Benedito â CE, na empresa CeaRosa Com. Exp. Imp. e Prod. de Flores Ltda em sua fase de produÃÃo de mudas, e no TecFlores â Escola de Floricultura do Governo do Estado do Cearà em sua fase de plantio em casa de vegetaÃÃo. Foram testados seis substratos (100% areia, 100% pà de coco seco, 50% areia + 50% pà de coco seco, 75% pà de coco seco + 25% areia, 25% pà de coco seco + 75% areia e 25% casca de arroz + 75% pà de coco seco). O delineamento experimental utilizado foi anÃlise fatorial com dois fatores, onde foram avaliados os parÃmetros enriquecimento e os seis substratos. Na fase de produÃÃo de mudas, foram avaliados a percentagem de pega das mudas, o comprimento de raÃzes, a massa seca das mudas e o teor de macro e micronutrientes presentes nas mudas. Na fase de produÃÃo e desenvolvimento em casa de vegetaÃÃo, foram avaliados o nÃmero de brotaÃÃes emitidos pelas plantas e os teores de macro e micronutrientes do tecido foliar das plantas. O enriquecimento da soluÃÃo nÃo afetou a percentagem de pega das mudas, independentemente do substrato utilizado, mas afetou o comprimento de raÃzes e a massa seca das mudas. A produtividade da roseira nÃo foi afetada pelo substrato e nem pelo enriquecimento deste durante o processo de enraizamento.

Abstract:
Sciadopitys verticillata was subjected to three propagation treatments designed to inhibit coagulation of its latex-like sap at the cut ends of the stem cuttings. Twenty-four hour soaking in water prior to rooting hormone application significantly enhanced production of adventitious roots. Old wood stem cuttings from shade-grown trees rooted at higher proportions than stem cuttings collected from sun-grown trees. Height, age, and place of origin of the source trees were not important factors in successful rooting. Antibacterial activity against some human pathogens and soil bacterial species was detected in latex application trials but the antibiotic activity was not related to the bacterial Gram reaction. The latex-like sap inhibited none of four plant pathogens tested. A suspension of the water insoluble latex-like sap of S. verticillata had a pH of 5.8. Antibacterial activity of S. verticillata sap was heat stable, which indicates the activity was not protein-based.

The cultivation of black pepper (Piper nigrum L.) for commercial purposes, in the State of Espírito Santo, began in the 70s, being the cv. Bragantina currently the most representative among crops in this State. The urge to keep its status in the cultivation of this specific kind of spice demands, urgently, further studies and therefore, thorough research using appropriate technologies for the region. In this sense the quality of mother plants begins with the production of seedlings of excellence. Despite the experience of the greenhouse workers in the region to produce nursery plants by cuttings, the steps in this process should be thoroughly inspected to ensure maximum efficiency. The study aimed to investigate the system of production of black pepper cuttings, including the efficiency of substrates used in the nurseries. It was requested to the Ministério da Agricultura, Pecuária e Abastecimento (MAPA) the location of nurseries in accordance with applicable law and based on the information provided technical visits were made to 11 nurseries, recorded through a questionnaire. Samples of the substrates used in the production of seedlings were collected. The responses from the questionnaires were tabulated and converted into graphs of relative frequency for better contextualization of the situation, and the substrates were used to assemble a factorial experiment 11 (substrates) x 2 (presence or absence of 3-butyric acid (IBA)) aiming to evaluate the rooting of black pepper grow Bragantina conducted in randomized block design with four replications of 16 cuttings in a greenhouse located in the Centro Universitário Norte do Espírito Santo, in São Mateus-ES. It was found that there is no uniformity in seedling production, in the nurseries infrastructure nor the techniques used. The differences are related to the origin of the parental plants, plant propagation, and management for seedling growth, ensuring, through analysis, the difference in chemical composition, physical and biological substrates of, mainly influenced by the diversity of the source of organic matter and the use or not of lime and fertilizers. It was concluded that, despite all the nurseries are registered at the Registro Nacional de Sementes e Mudas (RENASEM) and comply with the legal requirements in force, we still need to research and study the differences so that the production of black pepper cuttings can exceed its excellence in results. The quality of the rooting of black pepper on the substrates used by nurserymen, was statistically analyzed by multiple comparisons (Tukey or Scott-Knott in 5% level of probability), and it was found significant increase in the percentage of rooting with the use of IBA and also a reasonable difference in the quality of the rooting between substrates
O cultivo da pimenteira-do-reino (Piper nigrum L.) para fins comerciais, no Espírito Santo, iniciou-se na década de 70, sendo hoje a cv. Bragantina a mais representativa nas lavouras capixabas. A pipericultura no Espirito Santo necessita urgente de estudos e pesquisas para continuar a ser destaque de produtividade, com tecnologias apropriadas para a região. Neste sentido a qualidade das plantas matrizes inicia-se com a produção de mudas de excelência. Apesar da experiência dos viveiristas da região em produzirem mudas por estaquia, as etapas deste processo devem ser muito bem inspecionadas para garantir o máximo de eficiência. O estudo teve como objetivo investigar o sistema de produção de mudas de pimenteira-do-reino e a qualidade dos substratos utilizados nos viveiros. Foi solicitado ao Ministério da Agricultura Pecuária e Abastecimento (MAPA) a localização de viveiros em conformidade com a legislação pertinente, e mediante as informações prestadas foram realizadas visitas técnicas a 11 viveiros, registradas por meio de um questionário. Coletaram-se amostras dos substratos utilizados na produção de mudas. As respostas dos questionários foram tabeladas e transformadas em gráficos de frequência relativa para melhor contextualização da situação. Os mesmos substratos foram utilizados para montar um experimento fatorial 11 (substratos) x 2 (presença e ausência de ácido-3-indolbutírico (AIB), visando avaliar o enraizamento de estacas de pimenteira-do-reino cv. Bragantina, que foi conduzido em blocos ao acaso com quatro repetições de 16 estacas, na casa de vegetação localizada no Centro Universitário Norte do Espírito Santo, no município de São Mateus-ES. Constatou-se que não existe uniformidade na produção de mudas, na infraestrutura dos viveiros e nas técnicas utilizadas. As diferenças estão relacionadas à origem das plantas matrizes, ao material propagativo, e ao manejo durante o crescimento das mudas, ficando confirmada pelas análises, diferenças na composição química, física e biológica dos substratos, influenciadas, principalmente, pela diversidade da fonte de matéria orgânica e a utilização ou não de corretivos e adubações. Conclui-se que, apesar de todos os viveiros serem registrados no Registro Nacional de Sementes e Mudas (RENASEM) e estarem em conformidade com as exigências legais em vigência, ainda é necessário pesquisar e estudar as divergências para que a produção de mudas de pimenteira-do-reino possa alcançar a excelência nos resultados. A qualidade do enraizamento de estacas de pimenteira-do-reino nos substratos utilizados pelos viveiristas, foi analisada estatisticamente por testes de médias (Tukey ou Scott-Knott em nível de 5% de probabilidade), e constatou-se aumento significativo na porcentagem de enraizamento com a aplicação de ácido indolbutírico, e diferença significativa na qualidade do enraizamento entre os substratos
