“…Vegetative propagation by stems and root cuttings are the main forms of propagation used in Rubus species because it is possible to obtain large amounts of genetically identical seedlings in a short period [7]. Cutting size and the application of indolebutyric acid (IBA) significantly influence the rooting process and consequently the obtaining of seedlings using the cutting technique [8].…”

Aim: The climbing shrub Rubus erythroclados Mart. ex Hook. f. (amora-verde) has great food (fruits) and medicinal (leaves) potential. However, this species remains understudied. The objective of this study was to evaluate the interaction between cutting size and IBA concentration in the vegetative propagation of R. erythroclados by stem cuttings. Study Design: The experimental design used was completely randomized in a 3x5 factorial combination. The cutting size factor was represented by three levels (10, 15 and 20 cm) and IBA concentration factor by five levels (0, 1,000, 2,000, 3,000 and 4,000 mg L-1). Results: There was an interaction between the factors in 13 of the 19 variables analyzed, being: live cuttings at 30 and 60 days, live cuttings with callus formation, sprouted cuttings at 30, 60 and 90 days, rooted cuttings, shoot number, shoot diameter, root number, root length, length of the largest root and root diameter. Size increase of the R. erythroclados cuttings caused a decrease in the phytotoxic effect of IBA in the development of the aerial part. The effect of IBA in response to rooting induction, in the larger size of R. erythroclados cuttings, required an increase in IBA concentration compared to the cuttings of shorter size. Conclusion: Cuttings of 10 and 15 cm treated with 1,000 mg L-1 of IBA showed greater rooting (20.0%) compared to the other treatments, being, therefore, indicated for the vegetative propagation of R. erythroclados by stem cuttings.

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

“…According to Silva et al (2012), stem cuttings of raspberry give better results than root cuttings and do not require treatment with IBA. In other species such as Pinus taeda (Alcantara et al, 2008) and Rubus fruticosus L. (Tadeu et al, 2012), the rooting percentage decreases with the supply of IBA.…”

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.
