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.
