Abstract

The aim of this study was to determine how lipids, total soluble sugars and starch are degraded during the germination process of crambe seeds (FMS Brilhante Cultivar). The experiment consisted of collecting seeds during every day of the germination test (0, 1, 2, 3, 4, 5, 6 e 7 days) during which were also held the germination counts. After collection, the proportion of seeds and / or seedlings was designed for the determination of water content, and the other part was separated to perform biochemical analysis. The study adopted a completely randomized design with four replications and the means were compared by regression analysis. Crambe seed reserves showed degradation since the metabolic activation with increased germination in that lipid, soluble sugars, and starch are degraded.

 

Key words: Lipids, total soluble sugars, starch.
