Abstract The objective of this work was to evaluate the rooting of herbaceous cuttings of CAMB-06 and APU-04 acerola cherry selections associated with the use of indolebutyric acid (IBA) and a concentration of aqueous extract of coco-grass. Cuttings were treated by immersion with different concentrations of IBA (0; 1,000; 2,000; 3,000; 4,000 mg L-1) and one application of aqueous extract of coco-grass in proportion 100% and placed to root in plastic boxes containing vermiculite. The experimental design was a completely randomized in a 2×6 factorial arrangement (two acerola cherry selections and six solutions for rooting) with four replicates of ten cuttings. After 90 days of cutting, the following variables were evaluated: cutting survival (%); leaf retention (%); rooted cuttings (%); sprouting (%); number of roots per cutting (%); length of roots (cm) and dry mass of roots per cutting (g). It was concluded that the application of IBA at 4,000 mg L-1 presented a better root development, resulting in a higher percentage of rooted cuttings and higher number and dry mass of roots in relation to IBA at 0 mg L-1 for CAMB-06 selection, while the APU-04 selection can be efficiently multiplied by herbaceous cuttings without the use of IBA. Under the conditions that the trials was conducted, the application of 100% aqueous extract of coco-grass was not effective in promoting the rooting of cuttings of CAMB-06 and APU-04 acerola cherry selections.

Root Growth And Development

Association between auxins and plant growth-promoting bacteria can stimulate root growth and development of fruit crop nursery plants, and can be a promising biological alternative to increase the rooting of cuttings. The objective of this study was to assess the viability of producing ‘Powderblue’ blueberry nursery plants from cuttings using different doses of indolebutyric acid (IBA) in association with Azospirillum brasilense. The following treatments were tested: 0 (control); 500 mg L−1 of IBA; 1000 mg L−1 of IBA; A. brasilense; 500 mg L−1 of IBA + A. brasilense; and 1000 mg L−1 of IBA + A. brasilense. The experimental design was completely randomized, with six treatments and four replicates, and each plot (box) consisted of 10 cuttings. The boxes were arranged in a mist chamber with an intermittent regimen controlled by a timer and solenoid valve. After 90 days, the following variables were assessed: rooted cuttings; survival of cuttings; foliar retention; sprouting; cuttings with callus; root dry mass per cutting; number of roots per cutting; and root length. It was observed that the application of IBA with the A. brasilense rhizobacteria increased the number of roots of ‘Powderblue’ blueberry cuttings, while the treatments with IBA alone and IBA 1000 mg L−1 + A. brasilense increased the root length of cuttings. However, treatments with IBA and A. brasilense had no impact on % rooted cuttings and % survival of cuttings.

ABSTRACT: Eplingiella fruticosa (Salzm. ex Benth.) Harley & J.F.B. Pastore, also known as “alecrim de vaqueiroâ€� or “cowboy rosemaryâ€�, is a woody, perennial, and aromatic shrub that growsin the states of northeast Brazil, with the exception of Alagoas, Maranhão, and PiauÃ. The plant is widely used in this region and has analgesic, vasodilator, anti-inflammatory, and larvicidal properties.The objective of this study was to evaluate the effect of different substrates and indolebutyric acid (IBA) on cuttings of E. fruticosa for identifying effective practices for the vegetative propagation of this species. Apical cuttings with a standardized length of 10cm and two pairs of leaves were harvested from mother plants in the vegetative stage. Two experiments were conducted: the first experiment tested the effect of three substrates (commercial, commercial + vermiculite, and commercial + vermiculite + humus) and the second experiment evaluated five concentrations of IBA (0.0, 1.0, 2.0, 3.0, and 4.0gL−1) and three growth periods (30, 45, and 60 days). The experimental design was randomized blocks with four replications. The analyzed variables were survival of cuttings, number of rooted cuttings, root length per cutting (RLC), number of buds per cutting (NBC), leaf dry mass (LDM), root dry mass (RDM), and total dry mass (TDM). In thefirst experiment,there were significant differences in RLC, NBC, LDM,RDM, and TDM, with a better growth using the commercial substrate. In the second experiment, there was no interaction between the evaluated parameters. However, there was a positive associated effect of IBA addition and the growth period on RLC, NBC, LDM, and RDM. The highest predicted value was attained for a concentration of 1.5g L−1IBA and a growth period of 60 days, for the above-mentioned variables.

ABSTRACT Propagation by cuttings is an alternative for obtaining citrus rootstocks. The exogenous application of indolebutyric acid (IBA), cutting collection season and genotypes used may affect the rooting and vegetative growth of citrus rootstocks cuttings. Two experiments were conducted to study the influence of these factors. In the first one, semi-hardwood cuttings from the 'Sunki' mandarin hybrids H49 and H77 were collected in the fall and late spring of 2013 and treated with IBA (0 mg L-1, 1,500 mg L-1 and 3,000 mg L-1). For each collection season, a 2 x 3 (two genotypes x three IBA concentrations) factorial scheme was adopted, in a randomized blocks design. In the second experiment, the development of cuttings that rooted in the late spring was evaluated until grafting. In this case, a completely randomized experimental design was adopted, with the hybrids H49 and H77. The IBA treatments positively influenced rooting and number of roots only in the fall collection, peaking at 23.3 % of rooted cuttings. In the late spring collection, rooting was close to 100 %, with the IBA treatment being unnecessary. Around 50 % of cuttings from the 'Sunki' mandarin hybrids were ready for grafting at 14 months after cutting.

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.

In the commercial production of guava seedlings (Psidium guajava L.) the quality of the cuttings, homogeneity, high percentage of rooting are the factors important to be analyzed. Therefore, as the Século XXI cultivar is recent, it is necessary to do more studies regarding the behavior of this guava to the factors that aid in the rhizogenic process. The objective of this work was to verify the concentrations of indolebutyric acid (IBA) that provide the best rooting of cuttings herbaceous and semihardwood, as well as to verify the best kind of cuttings used for vegetative propagation the guava cuttings cultivar ‘Século XXI’. The experimental design was completely randomized in a 5 x 2 + 1 factorial design, beginning with five concentrations of IBA (0, 1000, 1500, 2000 and 2500 mg L-1), two kinds of cuttings (herbaceous and semihardwood) and one control treatment (immersed in distilled water for 12 hours), with four replications and 10 cuttings per plot. In relation of the variables: the percentage of cuttings live without roots, callus, number of roots and dry weight of shoots did not present significant interaction among treatments, not adjusting to any regression model. Therefore, concluding that the herbaceous cutting is the most indicated for the propagation of guava seedlings of ‘Século XXI’; The concentration of 2500 mg L-1 of IBA promotes a higher percentage of rooted semihardwood cuttings without leaf; The hormone solution diluted with alcohol 50% (v/v) resulted in toxicity for herbaceous and semihardwood cuttings cv. Século XXI.

ABSTRACT: Drimys brasiliensis Miers is an Angiosperm native to the Atlantic Rainforest, commonly known as cataia. Because of dormancy of its seeds, due to embryonic immaturity, production of cataia seedlings presents challenges regarding propagation of the species. Thus, cuttings emerged as a possible technique to be applied, diminishing plants production time and ensuring uniformity of rooting. Stem cuttings from current year shoots were collected in autumn/2012, prepared with 10-12cm in length, a bevel cut on base and straight on top, keeping two leaves, one leaf or no leaves in the apical portion. After disinfestation, bases of cuttings were submitted to the following treatments with indole-3-butyric acid (IBA) in 50% hydro-alcoholic solution: 100% water, 0, 500, 1500, 3000, 4500 and 6000mg L-1 IBA. A completely randomized experimental design was used, with 3 types of cutting x 7 IBA concentrations, with four replicates of 10 cuttings per experimental unit. After 120 days, the variables percentage of rooted cuttings, number of roots per cutting, length of the three longest roots per cutting, percentage of cuttings with callus, alive and dead, with new shoots and the cuttings maintaining the original leaves were assessed. The application of IBA had no influence on any of the assessed variables. Cuttings with two leaves presented the best rooting percentage (51.1%) and the lowest mortality (5.4%), when compared to cuttings with one leaf (35.0%) or without leaves (0.4%). Cuttings without leaves are to be avoided, since they present the highest mortality percentage (93.6%).

Abstract Blueberry cuttings are difficult to root, so alternatives that maximize their rhizogenic potential are essential for the expansion of the crop. The objective of this work was to evaluate the effect of the basal lesion and different methods of indolebutyric acid (IBA) on the rooting of ‘Woodard’ herbaceous cuttings, collected in two seasons. The experimental design used was completely randomized in a 3x2x2 factorial arrangement, totaling 12 treatments and five replications. The factors consisted of different ways of IBA application (talc and alcohol in the concentration of 1,000 mg L-1, and without IBA), season of collection (autumn and summer), and two types of cuttings (with and without lesion in the basal portion). Two hundred days after the beginning of the experiment, there was no significant effect of the basal lesion on the rooting of the cuttings. However, it was found that rooting is influenced by the season of collection, with greater leaf retention, dry weight, number of roots per cutting, length of roots and length of the largest root collected in summer. The application of IBA talc provided a higher percentage of rooted cuttings (61.0%) in relation to alcohol (31.0%) and control (41.0%) when collected in the autumn. There was no difference between seasons when IBA was applied with talc, however, the application with alcohol solution and the control resulted in higher percentages of rooted cuttings in the summer (70.0% and 67.0%, respectively). Summer was considered the best season to collect ‘Woodard’ blueberry cuttings, although the IBA applied with talc has increased the percentage of rooted cuttings in the autumn. The basal lesion did not promote an increase in rooting.

ABSTRACT: Lychee is one of the most popular exotic fruits in Brazil, and has both in natura and industrial potential. The objective of the present study was to evaluate the influence of the number of leaflets on lychee herbaceous cuttings treated with the indolebutyric acid (1000mg L-1). The experimental design was completely randomized, with 4 replications and 10 cuttings per experimental plot. Treatments consisted of cuttings with zero (0), one (1), two (2), three (3), and four (4) leaflets. After 180 days, the rooting and survival percentages and the number and length of roots were evaluated. The data were subjected to polynomial regression analysis. The increase in the number of leaflets was advantageus for all studied variables, with an increase in the survival, rooting of cuttings, and number and length of roots. The herbaceous cuttings of lychee tree are viable, provided that at least four leaflets remain in the herbaceous cutting.

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.
