Temperaturas e substratos para germinação e vigor de sementes de Euterpe oleracea Mart

Abstract

The objective of this study was to evaluate the influence of different substrates and temperatures for conducting tests of seed germination and vigor in Euterpe oleracea. The work was realized at the Seed Analysis Laboratory of (CCA-UFPB). The treatments were distributed in a factorial 4 × 4, four temperatures (20-30; 25; 30 and 35 °C) and four substrates (sand, Bioplant®, Plantmax® and vermiculite), used four replications each. Were evaluated the following characteristics: germination (%), germination speed index, length and dry mass of seedlings. The ideal conditions for testing the germination and vigor in Euterpe oleracea seeds are in vermiculite under temperatures of 20-30; 30 and 35 °C, sand to 30 and 35 °C, plantmax® 20-30 °C and bioplant® 35 °C.
