Asexual propagation of Bursera glabrifolia, Bursera copallifera, AND Bursera bipinnata under rooting treatments in plant nursery conditions

Abstract

Objective: To assess the propagation of cuttings of Bursera glabrifolia, Bursera bipinnata and Bursera copallifera under three rooting treatments, with four replications and eight plants per treatment.

Design/methodology/approach: Treatments consisted of soaking the base of the cuttings in 1.0% and 0.3% indole-3-butyric acid, and 0.12% alpha-naphthyl acetamide with 0.06% indole-3-butyric acid. Control cuttings were not subjected to any treatment.

Results: The species with greater rooting capacity was Bursera bipinnata (20%), followed by Bursera glabrifolia (6.25%); Bursera copallifera (2.34%) exhibited low rooting rates, though with good formation of calluses (17.1%) and aerial shoots. Products that helped rooting were indole-3-butyric acid at 1.0% with 13.6% and indole-3-butyric acid at 0.3% with 14.47%.

Limitations on study/implications: The solution 12% alpha-naphthyl acetamide with 0.06% indole-3-butyric acid promoted low root induction similar to that of the control cuttings that presented 7.5 and 2.5% of roots respectively

Findings/conclusions: 3% indole-3-butyric acid stimulates the formation of roots and aerial shoots in Bursera bipinnata, Bursera glabrifolia and Bursera copallifera
