Evaluation of Two Methods for Vegetative Propagation of Breadfruit (Artocarpus altilis) and a Proposal for the Establishment of an Agroforestry System

Abstract

A study was conducted at the fruit nursery of the Academic Farm, EARTH University, located in Guácimo, Costa Rica to cleft graft breadfruit (Artocarpus altlis) with breadnut (Artocarpus camansi) understock. Two treatments were analyzed: one with an understock of two months old and the other an understock of three months old. After five days, the two-month old understock produced only one successful graft of 30 tested (3.3 %), whereas there was a 36.7 % engraftment (11 grafts of 30) with the three-month old understock. Air layers on breadfruit branches were also prepared. Moss-like substrate and coconut water were used to promote rooting. Adult tree branches were used for the air layers. The results after two months showed that a low number of air layers produced roots (5 %), because only one of 20 layered branches developed roots successfully. Three schemes to incorporate breadfruit and other tropical fruits into an agroforestry system also were proposed.

 

Key words: air layers, Artocarpus altilis, Artocarpus camansi, breadnut, breadfruit, grafting, agroforestry systems.
