Study on Physiological Characteristics during Seed Germination of Styrax suberifolius
摘要
Abstract
[Objective]To study on physiological characteristics during seed germination of Styrax suberifolius. [Method]The germination per-centage and changes of seed reserve contents as well as certain enzyme activities of Styrax suberifolius seeds during the process of germination were determined. [Result]The results showed that the germination percentage climbed rapidly after sowing for 15 days, and it had the"S"curve before the germination percentage finally reached 18.5%;Meanwhile, the soluble sugar content showed a up-and-down changing pat-tern,while the starch performed oppositely;The soluble protein content progressively increased during the seed germination,reaching 256.18 mg/g FW;α+β amylase activities remained high at the first 20 days,and then dropping massively;POD activity peaked at 10 days after so-wing. [Conclusion]The relatively high amylase and POD activity helped the degradation of starch and the accumulation of soluble protein in S. suberifolius seeds during germination.关键词
