Propagación vegetativa de Dendrocalamus asper, Guadua angustifolia y Bambusa vulgaris (bambú), en el Vivero Bambunet del cantón Archidona, provincia de Napo

Abstract

Due to the ecological and economic importance of bamboo, the forest area aims to emphasize reforestation with these species in the tropical regions of Ecuador. The present research proposes: vegetatively propagating Dendrocalamus asper, Guadua angustifolia and Bambusa vulgaris (bamboo) in the Bambunet vivarium of Archidona canton, in Napo Province; Through the branch segment method, using two phytohormones to improve rooting: indolebutyric acid (AIB) and naphthalacetic acid (ANA). 450 branch segments of the three species were propagated. A randomized complete desing with factorial structure was applied, with 10 replicates and 5 plants of each experimental unit. The factors evaluated were: the species of bamboo and the hormones applied, each with three levels. With the evaluated hormones the expected results were not obtained, in relation to the survival the highest percentages were obtained with the control (without hormone) and Dendrocalamus asper, in relation to the number of outbreaks showed a greater amount of Dendrocalamus asper, but without difference statistics of the applied hormones, although there were no statistical differences, was observed in Bambusa vulgaris with the hormone AIB a considerable amount and length of roots. The propagation of bamboo is considered economically profitable, being an income for the producers of the province, which is extremely important to encourage the propagation of multipurpose species in the Amazon.
