摘要
综合有关气孔的前馈式反应、反馈式反应和周期性振动及其对果树叶水势的调控研究看出,在水分胁迫的情况下,前馈式反应可以主动阻止叶水势下降,而反馈式反应则被动地阻止叶水势进一步下降。气孔的周期性振动对叶水势的影响比较复杂,需作进一步研究。
The concepts of stomatal feed-forward regulation,backward regulationand oscillation, and their control to leaf water potential (LWP)in fruit trees were dis-cussed in this paper,In the case of water stress,feed-forward regulation, could preventdecrease of LWP actively, whereas backward regulation retarded further decrease ofLWP passively. The effect of stomatal oscillation on LWP was complex, and furtherstudy on it was needed.
