Abstract

Abstract: Diurnal change of water use efficiency (WUE) and net photosynthetic rate (Pn) are important processes on crop production and physiological mechanism.The paper analyzed the physio-ecology adaption of spring wheat (Triticum aestinum L.)and summer corn(Zea mays L.)under different water treatment.The result showed that WUE and Pn are markedly influranced by water shortage, the most markedly time stage is in the afternoon(12-16 hr).The main way of Pn change to water shortage in the moring stage is determined mainly by stomata, and in the afternoon stage mainly by non-stomata.Meanwhile, WUE and Pn reaction to water shortage condition not only related to water potential of leaf, but also to the environmental factors, especially to relative humudity(RH)and leaf temperature(Tl).

Key words: Drought, Crops, Water use efficiency(WUE), Photosyntheic rate(Pn), Diurnal change
