Propagação vegetativa de liamba, planta medicinal

Abstract

The liamba (Vitex agnus castus L.) is used as a medicinal species in Brazil and presents compounds with similar chemical structure to progesterone. To evaluate the propagation of liamba two experiments were carried out. The first, using shoot cuttings with 20 cm long, leafless and classified into two groups, apical and basal. The cuttings were standardized in their thickness of 3 to 5 mm in diameter and 40 units of each type were placed in polyethylene bags (10 × 30 cm) filled with soil + manure in the volumetric ratio of 2:1. The second, with shoot minicuttings of the plant canopy with 3 to 5 cm long, without leaves and in a randomized block experimental design with four replications of 20 minicuttings, in a factorial 2 × 3. The treatments were kind of mini-cuttings (with and without hell) and substrate (soil, soil + cattle manure and soil + compost). The vegetative propagation of liamba can be made by basal cuttings or minicuttings with heel in soil + compost.
