基于PEG胁迫响应的不同地理种源沙拐枣抗旱性评价

The physiological indices such as proline(Pro),soluble sugar(SS),malondial dehyde(MDA),the activity of super oxide dismutase(SOD) and peroxide enzyme(POD) of Calligonum mongolicum Turcz.from different geographical provenance in Gansu province,namely C.mongolicum Turcz.From Jiuquan,C.mongolicum Turcz.from Zhangye,and C.mongolicum Turcz.from Wuwei,were determined under different PEG concentration treatment and their drought resistances were evaluated with membership function.Results showed that the change tre...
