摘要:
通过野外观测，利用统计分析对毛乌素沙地南缘的赖草蒸腾速率与叶水势的关系进行了初步的研究。结果表明：赖草蒸腾速率呈现双峰变化；6月份的水势值要明显大于7月份，说明赖草7月份受到的干旱胁迫要大于6月份；通过相关性分析，建立了赖草蒸腾速率与叶水势间的一元回归模型。
Abstract:
An elementary study to the relation of transpiration rate and leaf water potential of A. dasystachys is made through field survey and statistical analysis. The result indicate: transpiration rate of A. dasystachys takes on two peak; the leaf water potential is in June more than in July, accounting for A. dasystachys is subjected to drought stress that is stronger in July than in June; through coherence analysis, the regression model of transpiration rate and leaf water potential of A. dasystachys is set up.
