INFLUÊNCIA DO SUBSTRATO NA EMERGÊNCIA DE PLÂNTULAS DE SAPOTA PRETA

Abstract

Aiming to evaluate seedling emergence of black sapote (Diospyros ebenaster Retz.) it was developed an experiment with seeds, collected on mature fruits, proceeding from Germoplasm Bank of Horticulture Department, University of São Paulo State, Jaboticabal, Brazil. Immediately after extracted, the seeds were washed, dried in paper and put in plastic box filled with the substrate studied, thus characterizing four treatments, as follows: Plantmaxâ; Coconut fiberâ; Sand; Soil mix [soil + sand + bovine manure (3:3:1)]. It was observed emergence percentage (E%) and rate of emergence speed (RES). The different substrates had statisticalinfluence on variable studied. The highest E% was obtained on soil mix, Plantmaxâ and Coconut fiberâ substrates and the best RES was observed on soil mix and Plantmax? substrates.
