Effects of IAA and IBA on the in vitro rooting of stem cuttings of Sechium edule (Jacq.) Sw
Journal Title: Biotecnología Vegetal - Year 2015, Vol 15, Issue 1
Abstract
This investigation was carried out with the objective of evaluating the response of shoots of chayote [S. edule (Jacq.) Sw.] to the application of indole-3-butyric acid (IBA) and indole-3-acetic acid (IAA) on the in vitro rooting phase. The effect of three culture media, modified from the proposed of Murashige and Skoog (MS) was studied: 1- 65% MS salt base, 2- 65% MS salt base + 0.05 mg l -1 of indolebutyric acid (AIB) and 3- 65% MS salt base + 3.0 mg l -1 -3-indole acetic acid (IAA). The variables evaluated were: number of roots, length and number of shoots per in vitro seedling. The best result were obtained when using 65% MS salt base with 3.0 mg l -1 of IAA. Significant differences (P<0.05) among treatments containing growth regulators was obtained for the variables number of roots and length of in vitro plantlets. In the UNA-730 accession root induction was obtained in a 65% MS salt base culture medium without growth regulators; however, when IAA and IBA was added the induction was 100%. The differences identified in this work with regards to the root induction were probably the combined result of genotype and specific culture conditions.
