野生大豆、半野生大豆和栽培大豆对苗期干旱胁迫的生理反应
Physiological Reaction of Glycine soja, Glycine gracilis and Glycine max to Drought Stress in Seedling Stage
摘要
Abstract
Wild,semi-wild and cultivated soybeans were pot planted in greenhouse and treated with drought stress at seedling stage. Chlorophyll content(CC) ,photosynthetic xaie(Pn) ,proline conlent(PC) ,malondialdehyde( MDA) content,relative electric conductivity(REC),soluble sugar content( WSS), superoxide dismutase( SOD) activity, peroxidase( POD) activity, hydro-genperoxidase(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 < semi-wild soybean < cultivated soybean; the increment of MDA, REC, SOD, CAT and POD were wild soybean < semi-wild soybean < cultivated soybean, while the increment of PC behaved negatively. Under drought stress, the physiological indexes of wild, semi-wild and cultivated soybeans changed obviously and the change amplitude of three types of soybean had a great difference, the performance of physiological indexes of wild soybean was better than semi-wild and cultivated soybeans.关键词
