SEED GERMINATION AND SEEDLING DEVELOPMENT IN THE BROCCOLI IN FUNCTION OF DIFFERENT SUBSTRATES AND TEMPERATURES

Abstract

This study aimed to evaluate the seed germination and seedling development of broccoli in function of different substrates and temperatures. The work was accomplished in the Laboratory of Technology and Analyses of Seeds at the Agrarian Science Center at the Universidade Federal do Espírito Santo (CCA-UFES), Alegre-ES, Brazil. A completely randomized design was used with four replications of 25 seeds, in a 2 x 6 x 4 factorial outline, with two lots, six substrates (Plantmax^® (S1); Plantmax^®+Fertium^® 1 g dm^-3 (S2); Plantmax^®+Fertium^® 2 g dm^-3 (S3); soil+sand+manure (S4); soil+sand+manure+Fertium^® 1 g dm^-3 (S5); soil+sand+manure+Fertium^® 2 g dm^-3 (S6), and four temperatures (20 ºC, 25 ºC, 30 ºC and 20-30 ºC). For seed germination and initial development of broccoli seedlings can be utilized the substrate Plantmax^® and Plantmax^® enriched with Fertium^®. The better percentages of germination occurred by using temperature of 25 ºC.
