propagação de araçazeiro e goiabeira via miniestaquia de material juvenil

Abstract

This study was carried out to evaluate the viability of the minicutting technique on rooting of juvenile material of cattley guava (Psidium guineense and Psidium cattleyanum) and guava (Psidium guajava), and seedling growth after transplanting and production of the ministumps under successive harvests. Three experiments were carried out in a randomized block design using three species and four replicates. Sixty-two days after cutting establishment, P. guineense, P. cattleyanum and P. guajava showed rooting percentages of 96%, 92% and 100%, respectively. P. guajava showed a minimum stem diameter of 8 mm at 110 days after transplanting and P. guineense and P. cattleyanum showed stem diameter of 7 mm after 140 days of transplanting. Minicutting production increased over successive harvests of sprouts. Based on these results, it is concluded that the minicutting technique is viable for multiplying cattley guava and guava.
