摘要/Abstract

摘要： 以盆栽苹果幼树为试材研究了土壤相对含水量与叶片水分利用效率(WUE)的关系,探讨了引起WUE变化的原因,结果表明,土壤相对含水量(SWC)52.0%时WUE最高.SWC从77.2%降至52.0%时,气孔导度下降,并使蒸腾速率(Tr)的下降幅度大于净光合速率(Pn)的降幅而导致WUE升高;SWC从52.0%降至20.1%时,WUE降低的根本原因在于羧化效率下降使Pn大为降低.干旱复水后WUE回升,但至复水第7天仍低于对照.土壤渍水当天WUE下降,第3天回升至对照水平,之后随渍水期延长WUE逐渐降低,淹水第6天羧化效率开始下降.

Abstract: The relationship between soil water content and water use efficiency (WUE) of apple tree leaf was examined,and the mechanism of WUE variation was also studied by using pot culture.The results showed that the WUE was upmost when soil water relative content (SWC) reached 52.0%.The increase of WUE when SWC decreased from 77.2% to 52.0% was mainly caused by the change of stomatal conductance.The decline of carboxylation efficiency resulted in the decrease of WUE when SWC decreased from 52.0% to 20.1%.The WUE returned up after being rewatered,but could not reach the control level within a week.The WUE decreased when the soil was waterlogged,but reached the control level in three days after being waterlogged.After the third day,the WUE decreased gradually with the extending of the time being waterlogged.On the sixth day being waterlogged,the carboxylation efficiency decreased.
