Cinco métodos de manejo de plántulas para la inducción de brotación de basales en la variedad de rosa Blush de los Andes (Rosa spp)

Abstract

The present study shows five techniques to induce the growing of plantules of a variety of Andean Blush rose (Rosa spp.). The techniques employed were as follows: in the first place, suffocation of plantules by semi-snapping prior to the growing of escobilla; second, suffocation of plantules by bowing, prior to the growing of escobilla; third, harvest of the first flower by the Russian cutting technique; fourth, suffocation of plantules by bowing prior to removing the first bud off in the manner of a chickpea; and fifth, removing the first flower bud by the Russian cutting technique plus removing the leaf buds from armpit shoots. The number of basals grown per treated plant was evaluated on a weekly basis, including the length in centimeters of each basal, the width in centimeters of each stalk, as well as the number of days (cultivation cycle) from planting of the plantules to the harvest at the same point of each basal stalk evaluated. As far as the number of basals per plant, no significant difference was found; as for the length of basals in centimeters, the best technique was the second, giving an average length of 97.21 cm per stalk, also for the width (diameter) with an average of 6.39 mm per stalk; as for the variable “cultivation cycle from planting”, the best results were obtained from the two first treatments; however, for the same variable but since the application of the treatments, the best results were obtained from the fifth technique.
