Germinação de Moringa oleifera Lam em diferentes temperaturas e fotoperíodos

Abstract

The aim of this study was to evaluate the germination of Moringa oleifera Lam under two incubation temperatures and two different photoperiod. The experiment was conducted at the Federal University of Mato - Grosso Campus of Sinop, in November 2015 specifically in seed analysis laboratory. The seeds were incubated at different temperatures for germination (20ºC and 30ºC) and different photoperiod (12 hours without light). For each treatment, the germination was carried out with 2 replications of 25 seeds. The tests were implanted in gerboxes with germitex paper moistened with distilled water. The root protrusion was used as germination parameter to achieve 2 mm calculated the Speed Index of Germination and the percentage of germination. The experimental design was completely randomized in a factorial 2 x 2 (2 temperatures and 2 photoperiod). As a result it was observed that the photoperiod and temperature affect the germination of seeds of Moringa oleifera Lam, wherein the temperature of 30 ° C favors and accelerates the recovery of metabolism of embryos and germination of M. oleifera is better and is more rapidly in the absence of light.
