摘要
为探究文冠果的耐旱机制,对文冠果幼苗进行不同程度的干旱胁迫处理,分析文冠果叶片的脯氨酸和可溶性蛋白含量变化。结果表明:随着干旱胁迫的加重,文冠果幼苗体内积累的脯氨酸含量随之增加。可溶性蛋白质含量在重度干旱处理下最高,表明重度干旱胁迫对可溶性蛋白含量影响最大,而中度干旱胁迫对可溶性蛋白含量影响较小,表明文冠果幼苗体内的可溶性蛋白质含量与干旱胁迫程度呈正相关。
In order to explore the drought tolerance mechanism of Xanthoceras sorbifolia,different degrees of drought stress were applied to Xanthoceras sorbifolia seedlings,and the changes of proline and soluble protein contents in Xanthoceras sorbifolia leaves were analyzed.The results showed that proline accumulation in Xanthoceras sorbifolia seedlings increased with the increase of drought stress.Soluble protein content was the highest under severe drought stress,which indicated that severe drought stress had the greatest effect on soluble protein content,while mild drought stress had little effect on soluble protein content,indicating that soluble protein content in Xanthoceras sorbifolia seedlings was positively correlated with the degree of drought stress.
