Substrata effect on <i>Magonia pubescens</i> St. Hil. seed emergence

Abstract

The objective of this work was to verify the substratum influence on the emergence of Magonia pubescens St. Hil. seedlings. Two experiments had been carried through: one using the whole seeds and another one using seeds without seedcoat. The experimental design was in randomized blocks, with four replications of 20 seeds, and the following treatments: a) sand, b) black soil, c) vermiculite, d) black soil+vermiculite (1:1), e) black soil+sand (1:1). The  whole seeds had the highest emergence on the substratum black soil and/or vermiculite, and the sand was the worst substratum, with 70% of emergence. The seedling emergence of seed without seedcoat was not affected by substrates. Regardless of the presence or absence of seedcoat the seedling growth was favored in the black soil substrate.
