不同供水条件对冬小麦光合特性及水分利用效率的影响
The Photosynthetic Characteristics and Water Use Efficiency of Winter Wheat in Different Water Supply Conditions
摘要
Abstract
In the paper,photosynthetic response to light intensity and CO2 concentration of flag leaf in winter wheat under different water treatments was studied in filling stage.And different water controls were designed for no water stress（CK） and water stress（WS）.Results showed that there was no difference in photosynthetic parameters between CK and WS treatments.However,there was significant difference in CO2 response curves.Stomata conductance and transpiration both decreased as CO2 concentration increased and WS is more sensitive than CK.Water use efficiency of CK was slightly higher than that of WS,which indicated that low water stress has not make much effect on physiological mechanism of winter wheat.关键词
