Abstract

GAMA, Juliana Simões Nobre et al. Temperatures and substrates for germination and vigor of Euterpe oleracea Mart. Seeds. Rev. Ciênc. Agron. [online]. 2010, vol.41, n.4, pp.664-670. ISSN 1806-6690.  http://dx.doi.org/10.1590/S1806-66902010000400021.

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 x 4, four temperatures (20-30; 25; 30 and 35 ºC) 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 ºC, sand to 30 and 35 ºC, plantmax® 20-30 ºC and bioplant® 35 ºC.
