Abstract
Abstract: Seed germination studies provide essential information for biodiversity conservation and ecological restoration programs. This work aimed to investigate the relationship between the substrates and the mobilization of reserves during germination of Ormosia coarctata seeds under different temperatures. Samples were collected every 48 h for up to 240 h for quantification of lipids, soluble sugars, starch, and soluble proteins. The optimum temperature range for germination was 25 to 35 °C. The highest germination percentages were obtained using sand or paper roll. Carbohydrate, lipid, and protein contents decreased during germination, regardless of temperature.
