| 摘 要： | 以野生、半野生和栽培大豆为材料,在旱棚盆栽条件下进行苗期干旱胁迫试验.对叶绿素含量、光合速率、脯氨酸含量、丙二醛(MDA)含量、相对电导率、可溶性糖(WSS)含量、超氧化物歧化酶(SOD)活性、过氧化物酶(POD)活性、过氧化氢酶( CAT)活性进行测定.结果表明,在干旱胁迫下,叶绿素含量、光合速率、可溶性糖含量、脯氨酸含量及SOD活性表现为野生大豆＞半野生大豆＞栽培大豆；而丙二醛含量、相对电导率、POD活性则表现为野生大豆＜半野生大豆＜栽培大豆.干旱胁迫下不同类型材料各生理指标与正常供水条件相比都发生不同程度的变化,叶绿素含量、光合速率降幅为野生大豆＜半野生大豆＜栽培大豆；脯氨酸含量增幅为野生大豆＞半野生大豆＞栽培大豆；而丙二醛(MDA)含量、相对电导率、SOD活性、POD活性,CAT活性增幅变化顺序为野生大豆＜半野生大豆＜栽培大豆.在干旱胁迫下,野生大豆、半野生大豆和栽培大豆的生理指标发生显著变化,3种类型大豆的变化幅度差异显著.野生大豆在干旱胁迫下生理指标的表现优于半野生大豆和栽培大豆.

| Abstract: | Wild,semi-wild and cultivated soybeans were pot planted in greenhouse and treated with drought stress at seedling stage.Chlorophyll content(CC),photosynthetic rate(Pn),proline content(PC),malondialdehyde(MDA)content,relative electric conductivity(REC),soluble sugar content(WSS),superoxide dismutase(SOD)activity,peroxidase(POD)activity,hydrogenperoxidase(CAT)activity were examined.Under drought stress,CC,Pn,WSS,PC and SOD activity were shown as wild soybean > semi-wild soybean > cultivated soybean,while MDA,REC and POD activity had opposite trend.Compared with CK,the variation degree of physiological indexes under drought stress varied greatly.The decreasing amplitude of CC and Pn were behaved for wild soybean
