Reguladores de crecimiento en la propagación vegetativa de Bambú gigante (Dendrocalamus sp) en condiciones de cámara térmica, en El Carmen, Manabí.

Abstract

The objective of this work was to evaluate the effect of growth regulators on the vegetative propagation of giant bamboo (Dendrocalamus sp), under thermal chamber conditions; for which five treatments T1 (0 ml/liter of alpha-naphthaleneacetic acid), T2 (0,5 ml/liter of alpha-naphthaleneacetic acid), T3 (1 ml/liter of alpha-naphthaleneacetic acid), T4 ( 1,5 ml/liter of alpha-naphthaleneacetic acid) and T5 (2 ml/liter of alphanaphthaleneacetic acid) arranged in a randomized block design with four replications. It was concluded that the vegetative growth of giant bamboo (Dendrocalamus sp) was not affected by the doses of alpha-naphthaleneacetic acid applied, but it did infer on the number of roots, being the dose (0,5 ml/liter of alpha-aphthaleneacetic acid naphthaleneacetic) the best with a greater number of roots (103,00) at 60 days after sowing. Finally, the benefit & cost analysis of the treatments showed that T2 had the highest relationship with .18, which implies that for every dollar invested, a profit of $3.18 dollars was obtained.
