| 摘 要： | 在盆栽条件下,以大豆(Glycine max)绥农10号为材料,通过人为控制水分(干旱和水渍处理),比较叶片中几种内源激素含量变化的差异,研究水分胁迫对大豆幼苗保护酶活性的影响.结果表明:干旱处理提高了大豆苗期叶片内赤霉素(GA)、脱落酸(ABA)的含量但也降低了玉米素核苷(ZR)和生长素(IAA)的含量,同时干旱处理提高了丙二醛(MDA)含量以及超氧化物歧化酶(SOD)活性;水渍处理降低了ABA含量和SOD活性,提高了IAA、GA以及MDA的含量.

| Abstract: | Suinong10,a soybean(Glycine max) cultivar,was used as materials in this study.Drought and water-logged treatments were employed to compare differences of several endogenous hormones and protective enzyme activities in soybean seedling leaves.The results showed that the content of GA and ABA were increased,the content of ZR and IAA were reduced with the drought treatment,the content of MDA and the activity of SOD was increased.Moreover,the content of IAA,GA and MDA were increased under the water stress,howev... |
