Mobilization of Storage Reserves in Dalbergia spruceana Benth. (Fabaceae) Seeds During Germination at Different Temperatures

Temperature may affect the mobilization and hydrolysis of storage reserves for energy production during seed germination. This study investigated germination performance reserve in Dalbergia spruceana Benth. seeds incubation at 20, 25, 30, 35, 40°C. The process was favored by 25 to 35°C negatively affected 20 At there reduction speed, however, without significantly compromising final percentage. results showed that lipids proteins are predominant metabolites D. seeds. Mobilization soluble sugars highest 30°C. 40°C, occurred more slowly, affecting finding, combined with changes lipid protein reserves, suggests products were used starch synthesis. Reserve patterns embryos influenced temperature, utilization efficiency occurring between 35°C.
