| 摘 要： | 为了研究低温层积处理在打破种子休眠、促进萌发过程中的作用机理,对层积不同时间的种子进行生活力和抗氧化酶系统测定、胚轴发育观察、抑制物检测。结果表明：随着香叶树种子层积时间的增长,种子萌发力及抗氧化酶活性均呈逐渐增加的趋势,而丙二醛含量呈不断下降的趋势;层积过程中水分条件的变化对层积结果有较大影响;香叶树的萌发抑制因素主...

| Abstract: | To study the mechanism of stratification in breaking seed dormancy and promoting the germination process, this study measured the activity of antioxidant enzyme system, observed the embryo development and tested the inhibitor content of Lindera communis seeds, which were treated under different lengths of stratification time. The results showed that with the stratification time growing, the capacity of germination and enzyme activities increased gradually in L. communis seed, but the content of malondialdehyde (MDA)level decreased in this progress. The change of moisture level had great impact on germination. The main factors inhibiting germination are mainly from endogenous inhibitors of seed coat. There is after\|ripening effect on embryo in L. communis seed, while stratification plays an important physiological role in breaking seed dormancy quickly. |
