摘　　要：通过水培和土培试验,研究不同浓度NaCl胁迫对叶底珠种子萌发及幼苗生长的影响,结果表明:随着NaCl浓度的升高,叶底珠种子的发芽率、发芽势、胚根长度和幼苗的高度下降,而游离脯氨酸含量、丙二醛(MDA)含量和POD活性增加。Through solution culture and soil culture experiments, effects of stress of different concentration NaCl on seed germination and seedling growth of Securinegco suffruticosa were studied in this paper. The resuits showed that the decrease happened in seed germination percentage, germinating energy, length of root and height of seedling, whereas dissociate proline content, MDA content and POD activity were obviously increased.
