干旱胁迫对柔枝松幼苗耗水的影响
The Effect of Drought Stress on Water Consumption of the Seedlings of Pinus flexilis James
摘要
Abstract
[Objective] The aim was to study water consumption of the seedlings of Pinus flexilis James. [Method] Selecting six 1 -year transplanting seedlings, water consumption and rates of water consumption under different drought periods were studied. [ Result ] The study showed that the daily variations in quantities and rates of water consumption (WCQ and WCR) of seedlings were single peak type,The variation of quantity of water consumption and water consumption rate of provenances Rsi was the smallest,and the daily variations in quantities and rates of water consumption (WCQ and WCR) of seedlings were steady,Rs and RI decreased greatly. According to water consumption and water consumption rate,Rsi was more drought tderance. [Conclusion]The study provided theoretical basis for the study on drought resistance mechanism of Pinus flexilis James.关键词
