摘要: 以河北省当年棉花区试对照品种DP99B为对照,在足水和干旱两种条件下对衡科棉369抗旱性生理特性进行了研究,结果表明:衡科棉369离体叶片失水速率较低,在干旱胁迫下叶片含水量的变化较小。脯氨酸增加较多,超氧化物歧化酶(SOD)含量增加较多。说明衡科棉369比对照DP99B抗旱性强。

Abstract: Using the check variety DP99B of current-year in Hebei province cotton regional trials as the comparison,we studied the Heng ke cotton 369 with the physiological characteristics of drought resistance,under be rich in water and drought in the two kinds of conditions. The result showed that: the dehydration rate of in vitro leaves in Heng ke cotton 369 was lower. Under the arid deficit,the change of leaf moisture content was smaller. The proline's content increased many,the content of superoxide dismutase (SOD) increased much. The test showed that Heng ke cotton 369 had a strong drought resistance compared with the comparison DP99B.
