摘　　要：对翅荚木种子分别采用20%聚乙二醇(PEG)6000溶液渗透调节和60℃始温水浸种,研究2种预处理对翅荚木种子活力的影响.结果表明:采用20%PEG处理的翅荚木种子的活力指数、脱氢酶(DH)活性、过氧化物酶(POD)活性以及根系活力均明显高于60℃始温水浸种的种子,而丙二醛(MDA)含量和相对电导率则明显低于60℃始温水浸种的种子,说明采用20%PEG渗透调节处理能显著提高翅荚木种子的活力.The seeds of Zenia insignis Chun were dealt with 6000 solution of 20% PEG and with 60℃ water, respectively. This is to study the effects of two pretreatments upon the seeds. The results indicate that the vitality index and dehydrogenase activity, proxydase and root system of the seeds immersed with 6000 solution of 20% PEG are higher than the seeds with 60℃ water but the malonaldehyde content and relative conductivity are lower. Thus, the pretreatment of 6000 solution of 20% PEG can evidently increase the activity of Zenia insignis Chun seeds.
