“…In our study, we found that the softwood cutting of sapucaia with rooting formed callus near the cut. A similar finding was reported by Souza & Lima (2005) and Barbosa et al, (2007) for cuttings of the species Spondias mombin and hybrids of Pyrus pyrifolia × Pyrus communis (pear), respectively, showing that adventitious roots were formed near the cambial region and on the callus tissue at the base of the cuttings.…”

Our study sought to evaluate the rooting capacity of indole butyric acid (IBA)-treated stem cuttings and the efficiency of the vegetative rescue technique of adult and transitional parent trees of Lecythis pisonis. Softwood, hardwood, and semi-hardwood leafless cuttings treated with IBA (0; 2,000; 4,000; 6,000; and 8,000 mg kg -1 ) were tested in a randomized block design with four replicates and 10 cuttings per plot. The growth of epicormic shoots was also evaluated in 60-cm branches removed from the tree canopy and kept in greenhouse for 60 days. Cuttings from adult trees did not form roots. Softwood cuttings from transitional trees had a very low rooting percentage. In both cases, no influence of IBA concentrations were observed. The use of the sectioned-branch technique was feasible for inducing sprouts.

“…Thus, it is important to establish an ideal concentration for root induction for each species (Fachinello et al, 1995;Mansseri-Lamrioui et al, 2011). In Ficus carica L. plants, the IBA growth regulator at the concentration of 25 µM led to the best rooting percentage and the largest number of roots (Barbosa et al, 2007). Konan et al (2007) observed that the effect of the ANA growth regulator at the concentration of 1 mg.L -1 varied according to the genotype oil palm.…”

In vitro ROOTING OF TENERA HYBRID OIL PALM (Elaeis guineensis Jacq.) PLANTS1

Oil palm is a woody monocot of economic importance due to high oil production from its fruits. Currently, the conventional method most used to propagate oil palm is seed germination, but success is limited by long time requirements and low germination percentage. An alternative for large-scale propagation of oil palm is the biotechnological technique of somatic embryogenesis. The rooting of plants germinated from somatic embryos is a difficult step, yet it is of great importance for later acclimatization and success in propagation. The aim of this study was to evaluate the effect of the auxins indole acetic acid (IAA) and indole butyric acid (IBA) on the rooting of somatic embryos of Tenera hybrid oil palm. Plants obtained by somatic embryogenesis were inoculated in modified MS medium with 10% sucrose and 0.6% agar and supplemented with IAA or IBA at concentrations of 5 µM, 10 µM, and 15 µM, and the absence of growth regulators. After 120 days, the presence of roots, root type, length of the longest root, number of roots, number of leaves, and shoot length were analyzed. Growth regulators were favorable to rooting; plants cultivated with IBA growth regulator at 15 µM showed higher rooting percentage (87%) and better results for the parameters of number of roots (1.33) and shoot length (9.83).

Vegetative propagation of pear rootstocks using semi hardwood cuttingsThe objective of this work was to evaluate the technical viability of the vegetative propagation of the pear rootstocks 'Taiwan Nashi-C', 'Taiwan Mamenashi' (Pyrus calleryana Dcne.) and 'Seleção IAC-1' (Pyrus spp.) using semi-hardwood cuttings. The experiment was conducted in a nursery with an intermittent mist system at the Propagation Center Laboratory of the Botanical Garden, Instituto Agronômico de Campinas (IAC), SP, Brazil. The experiment was arranged in a 3 x 4 factorial scheme (rootstocks x indolebutyric acid doses), with five repetitions of 20 cuttings, in a complete randomized design. Results obtained 60 days after grafting showed that: a) the propagation of 'Taiwan Nashi-C', 'Taiwan Mamenashi' and 'Seleção IAC-1' using semi-hardwood cuttings is technically viable; b) among the studied rootstocks, 'Taiwan Nashi-C' showed the highest rooting percentage, lowest callus percentage, highest root length and root number per cutting; c) rooting of semi-hardwood cuttings required application of indolebutyric acid, and the doses 4000 mg.L -1 and 6000 mg.L -1 provided the highest adventitious rooting; d) the tested doses of indolebutyric acid were not phytotoxic to semi hardwood cuttings of the studied genotypes.
