| 摘 要： | 不同作物品种对环境因子的响应不同,而对作物生长影响最大的环境因子是光照和CO2浓度。研究不同冬小麦品种对环境因子的响应非常有意义。试验于2006年3-6月在中国科学院栾城农业生态试验站进行,采用LI-6400便携式光合仪测定了8个冬小麦品种在不同光照和CO2浓度条件下光合作用的变化。结果表明:光合作用对光强和CO2浓度响应的特征参数,在不同冬小麦品种间表现出明显的差异;叶片水分利用效率在不同冬小麦品种间差异显著,并随着光照强度和CO2浓度的增加而呈二次曲线变化。

| Abstract: | There was significant difference in the response of different crop varieties to the environmental factors which mainly included light-rate and CO2 concentrate.It was very necessary to study the response of environmental factors on the winter wheat growth.Field experiments were conducted to study response of light-rate and CO2 concentrate to photosynthesis on different winter wheat varieties from March to June in 2006.The results showed that photosynthesis parameters of different winter wheat varieties in response to light-rate and CO2 concentrate presented significant difference.The significant difference of leaf water use efficiency(WUE) in different winter wheat cultivars was observed.Leaf WUE changed with the increase of light-rate and concentrate of CO2. |
