Mate (Ilex paraguariensis A. St.-Hil) is an arboreal species of great economic and socio-environmental importance, which presents difficulties in the adventitious rooting process. The rhizogenic competence of vegetative propagules of mate can be attained by coppicing, but the factors that influence the success of this technique have not yet been elucidated. Therefore, the aim of this study was to evaluate the effects of the stock plant, time of shoot collection, treatment with indolebutyric acid (IBA) and diameter of vegetative propagules in the adventitious rooting of cuttings from shoots induced by coppicing of selected adult plants of mate. Shoots produced from coppiced 13SM01 and 13SM05 stock plants were collected at different times of the year to prepare single-bud cuttings. The cuttings were measured as their diameter in the central portion and treated with 0 and 3000 mg L-1 of IBA. After 60 days, cuttings were evaluated to determine survival and rooting percentages, number of roots, and length of the three largest roots. A completely randomized design was used in a 4 × 2 × 2 × 13 (collection times x stock plants x IBA treatment x diameter classes) factorial scheme with 15 replications. Competence for adventitious rooting was highest for stock plant 13SM05. Cuttings collected in November and February had the highest rooting percentages, without the need of IBA treatment. Cuttings from 13SM01 and 13SM05 with diameters smaller than 0.636 cm (classes 1 to 6) and smaller than 0.712 cm (classes 1 to 7), respectively, had the highest rooting percentages and differed significantly from cuttings with larger diameters. Thus, the results of the present study indicate that stock plants, time of shoot collection, and diameter of vegetative propagules influence adventitious rooting competence of mate cuttings from coppicing adult plants. Rooting of mate cuttings with lower rhizogenic competence is influenced by the application of 3000 mg L-1 of IBA.

ABSTRACT The competence of adult plants of mate (Ilex paraguariensis St. Hil.) to undergo adventitious rooting is essential to their vegetative rescue by cuttings. This study aimed to evaluate the adventitious rooting competence of adult mate plants, and then rescue these plants by making cuttings from epicormic shoots induced in different trunk positions. The percent survival and rooting of cuttings from epicormic shoots induced by girdling in seven adult plants were evaluated. The two stock plants whose cuttings had the highest rooting competence were further pruned and girdled to evaluate the effect of the position of epicormic shoots on their adventitious rooting competence. The potential success of rescuing of the same adult plants was also studied with cuttings of epicormic shoots induced by coppicing. The shoots were sectioned in single-bud cuttings, either treated with 3,000 mg L-1 indolebutyric acid or untreated, and then cultivated in a humid chamber for 60 days, and then the percent survival and rooting of cuttings was evaluated. In conclusion, we found that it is possible to rescue adult mate plants by cuttings from epicormic shoots induced by pruning, girdling, or coppicing. The adventitious rooting competence of cuttings differs among adult mate plants, and depends on the position of the epicormic shoots on the trunk from which epicormic shoots are collected.

In the search for more efficient techniques for the propagation of peach cuttings, this study aimed to evaluate the rooting of hardwood cuttings of peach rootstock genotypes under different indolebutyric acid (IBA) concentrations. In the winter of 2016, the basal end of cuttings of genotypes 1701-1, 1701-2, 102-1, 102-2, 202-1 and 'Okinawa' were dipped into solutions with five concentrations of IBA (0, 1000, 2000, 3000 and 4000 mg mg L-1) for 5 seconds. The cuttings were then placed in sand in plastic trays and kept in a mist chamber. The experiment was arranged in a 6x5 factorial, completely randomized design, with 5 replications, and each plot consisted of eight cuttings. After 59 days, the variables related to rooting and root quality were evaluated. Genotypes 102-1 and 202-1 showed high adventitious rooting potential in hardwood cuttings, with 76.8 and 66.5% of rooting, respectively. The concentration of 2000 mg.L-1 of IBA acid can be recommended for the treatment of hardwood cuttings of the tested rootstocks for propagation in the winter.

Plectranthus scutellarioides (L.) R. Br. is part of the Lamiaceae family and is commonly known as coleus, due to the genus denomination in the past. This ornamental plant species has been gaining importance in the floristic industry due to the great number of exotic cultivars available in the market. Coleus commercial exploitation by seeds is held up by genetic instability, which makes it usually being propagated through semi-hardwood stem cuttings and leaves have great importance in stem cuttings adventitious rooting. The objective of this study was to evaluate the presence or absence of apical leaves and the use of indolebutyric acid (IBA) in coleus stem cuttings rooting. Semi-hardwood coleus stem cuttings with 6 cm long were prepared with or without apical leaves, and then treated with hydroalcoholic solutions (50% v v-1) of 0, 1000 and 2,000 mg L-1 IBA. The propagules were planted in tubes containing vermiculite and kept for 30 days in a greenhouse under intermittent misting (24 ± 2 °C, Relative Humidity 90%) until final evaluation. The experiment was conducted in a completely randomized design, in a 3x2 factorial scheme (3 IBA concentrations x presence and absence of apical leaves). The rooting was evaluated after 30 days. Stem cuttings with and without apical leaves has 100 and 57% rooting, respectively. Stem cuttings rooting did not vary according to IBA concentrations. Roots length and number were higher in stem cuttings with apical leaves in comparison to leafless ones, regardless IBA concentrations. On average, 97.7% sprouting was observed in cuttings with apical leaves, significantly higher rates when compared to the average of 2.2% on leafless cuttings. The presence of apical leaves is fundamental for coleus stem cuttings rooting and the use of IBA is not required for this species propagation.

Azadirachta indica A. Juss. of the Meliácea family originates from India. It is considered important in Brazil due to its multiple uses. The plant is usually propagated by sexual reproduction (seeds), however, after harvest the seeds have to be sown as soon as possible because they lose germination viability very quickly. The use of juvenile propagules for A. indica seedlings propagation is a viable option, since there is a high demand in the semi arid regions due to wide use in urban afforestation. The objective of this research was to evaluate the effect of fertilization regimens and environments on obtaining Apical cuttings of juvenile origin and on the quality of cloned seedlings of Azadirachta indica. The research was carried out at the Forest Nursery of UFCG/Patos-PB, Brazil, with vegetative propagules (cuttings) obtained from three environments and two fertilization regimes: Biweekly and monthly, in addition to the control (without fertilization). The experiment was arranged in completely randomized design, factorial 3 x 3 (environments of origin of cuttings x fertilization regimes), with six replications, where each plot consisted of a cutting, totaling 54 experimental plots. Results indicated that propagation of Azadirachta indica through cuttings of juvenile origin is feasible, with an average rooting of 95.2%. It is recommended to use the monthly fertilization regimen, since in general it did not differ significantly from the biweekly regime. Fertilization provided better development and quality of the root system and aerial parts.

ABSTRACT: The objective of this study was to evaluate the effect of different types of cuttings and indolebutyric acid (IBA) concentration on the vegetative propagation of Lippia insignis , L. lasiocalycina , and L. thymoides . The experiment was conducted in a 2×5 factorial table, by using 2 types of cuttings (apical and medial) and 5 IBA concentrations (0, 250, 500, 750, and 1000mg·L-1) in a Completely Randomized Design (CRD), with 4 replications and 10 cuttings per plot. For the propagation of L. insignis , apical cuttings are the most suitable, whereas for L. thymoides and L. lasiocalycina species, both apical and medial cuttings may be used. The application of IBA is not necessary for propagation by cutting of the three species of Lippia.

The use of hormones is important in improving the propagation process. The objective of the experiment was to identify the best dose of indole butyric acid (IBA) hormone for the rooting of coffee cuttings of the typical variety through clonal propagation in the Amazon region. The experiment was carried out in two stages. Both stages were carried out under a Completely Randomized Design (CRD). The percentage of rooting of cuttings and the number of roots were evaluated. The coffee tree clones were collected from rust tolerant elite plants. In the laboratory, the cuttings were immersed for 10 minutes in fungicide and then in five doses of IBA hormone (1000, 1500, 2000, 2500, and 3000 mg L−1) of IBA. They were then placed in a microtunnel. With the best dose obtained in stage 1 of IBA (T4: 2000 mg L−1), which achieved a rooting percentage of 52.50% and 5.8 roots on average, stage 2 was installed for the evaluation of acclimatization conditions (greenhouse and nursery). Thirty plants of the Típica variety were evaluated per treatment. Regarding the results after 90 days, the greenhouse obtained the highest values with 72.22% survival, a plant height of 9.48 cm, 4.32 mm stem diameter, 6.53 leaves per plant, 9.65 cm leaf length, and 3.83 cm leaf width. The IBA hormone in a controlled environment such as the greenhouse achieves good vegetative propagation for the Típica variety.

Abstract Antitranspirants were evaluated for their effectiveness as a stock plant treatment to improve adventitious rooting of softwood cuttings of Syringa vulgaris L. ‘Montaigne’ (Montaigne lilac) and Chionanthus virginicus L. (white fringe tree). New shoots of S. vulgaris ‘Montaigne’ and C. virginicus were sprayed with one of two film-forming antitranspirants including Clear Spray® (aqueous acrylic emulsion) and sodium silicate; or Atrazine®, a herbicide that acts as a stomate-regulating antitranspirant. Shoot caliper of antitranspirant-treated lilacs increased more slowly than controls. Thirty days after treatment cuttings were taken from both taxa. All treatments resulted in 80 to 85% rooting of cuttings in lilac after 6 weeks, but cuttings from Clear Spray®-treated plants rooted more quickly. Chionanthus virginicus cuttings treated with Clear Spray® had significantly lower rooting (16%) than cuttings taken from Atrazine® treated plants (50%). In a subsequent experiment, antitranspirant treatment had no significant effect on shoot length or caliper of ‘Montaigne’ lilac. Photosynthetic rate, transpiration rate, and location of cutting on the stock plant were all positively correlated with shoot length, shoot caliper, and cutting diameter. Shoot length and caliper and cutting diameter, however, were all negatively correlated with root number and root length. There were no significant treatment effects on rooting percentage, root number or root length.

ABSTRACT The increasing demand for Ilex paraguariensis St. Hill (yerba mate) by-products generated the need for producing a greater quantity of seedlings and improve their quality. Thus, the objective of this work was to evaluate the efficiency of different substrates combined with base fertilization for Ilex paraguariensis seedlings, through morphophysiological parameters. The experiment was conducted in a completely randomized design, in a 5 x 3 factorial arrangement, and the treatments consisted of five substrate formulations combined with two fertilizers, and a control without fertilization, in November 2013. The I. paraguariensis seedlings produced in the substrate consisted of subsurface soil, cattle manure and charred rice hulls (2:2:1) presented the greatest heights (53.36 cm), stem diameter (6.80 mm), leaf area (692.52 cm2), root dry weight (6.2 g) and total dry weight (16.4 g). The efficiency of the different fertilizations used was similar regarding the seedling growth. The physiological parameters did not differ between treatments. The substrate composed of subsurface soil, manure and charred rice hulls (2:2:1) and fertilization with urea (0.7 g L-1) single superphosphate (8.0 g L-1) and potassium chloride (0.4 g L-1) is recommended for producing I. paraguariensis seedlings.

It was intended to evaluate the influence of indolebutyric acid (IBA) and zinc upon the rooting and development of rootstock of ‘Cravo’ lemon tree transplants of bare root to the modified hydroponic system in the grafting stage. Plants of rootstocks were treated by immersion of their root system into the different solutions tested for 24 hours. The experiment was arranged in a completely randomized design with seven treatments composed of IBA doses of 50, 100 and 200 mg.L-1 and Enervig® which contains in its formulation 33.92 g.L-1 of Zn at 60, 90 and 120 ml.L-1, and distilled water as a control with three replications and nine plants per plot, amounting to 189 plants , 15 cm tall. The rootstocks were transplanted to the tubes and taken to the modified hydroponic system, being evaluated (1) the development of the plants and (2) the time needed for the rootstocks to reach the grafting stage, considered ideal between 5 and 6 mm in diameter. The treatment with a solution of 100 mg.L-1of IBA proved superior to the others in the development of height and biomass yield and tended to provide greater stem diameter development. The grafting point was obtained, on average at 70 days after transplanting and the production of Rangpur lime trees in a hydroponic system may be recommended. When the root system of the ‘Cravo’ lemon tree was treated with 100 mg.L-1 solution the IBA grafting point was obtained at 45 days after transplanting.

ABSTRACT Passiflora mucronata Lam. is resistant to Fusarim oxysporum f. passifloraceae and therefore can be used as rootstock for the species Passiflora edulis Sims. f. flavicarpa. The rootstocks in this case can be vegetatively propagated through cuttings. The objective of this study was to evaluate the effect of different types of cuttings and different concentrations of indole-3-butyric acid (IBA) on the adventitious rooting of P. mucronata. The experiments were arranged in a completely randomized design with four replications of 16 cuttings each. In Experiment 1, the treatments consisted of the different types of cuttings from mother plants grown in protected environment: shoot tips; two leaves and two nodes; one leaf and one node; leafless with two nodes; leafless with one node. In Experiment 2, the cuttings were taken from field plants and treated with the following IBA concentrations: 0; 1000 mg kg-1 (0.0036456 mol L-1); 1500 mg kg-1 (0.0054684 mol L-1) and 2000 mg kg-1 (0.0072912 mol L-1). The characteristics evaluated in the experiments 1 and 2 were: survival (1 and 2); budding (1 and 2); shoot number (2), shoot length (2), number of shoot leaves (2);shoot dry mass (2); callusing (1); rooting (1 and 2); root number (1 and 2), largest root length (1 and 2), root volume (1 and 2), and root dry mass (1 and 2). We found that, instead the shoot tips, the cuttings of the type leafless with two nodes are the best for P. mucronata rooting. Neither the cuttings from greenhouse plants nor the cuttings from field plants require growth regulators for rooting of P. mucronata cuttings of the type leafless with two nodes.
