土壤水分对冬小麦幼苗光合特性及其相关因子的影响

Study on Photosynthetic Characteristics of Winter Wheat Seedling and the Relationship between Photosynthetic Rate and Influence Factors under Drought

采用盆栽试验,研究了不同土壤水分条件下冬小麦幼苗光合及其影响因子的关系。结果表明:光合速率和叶绿素含量均随土壤水分的减少而呈下降趋势。并且,通过逐步回归,获得了不同土壤水分条件下冬小麦幼苗光合速率及其影响因子的最优回归模型。

In this paper the photosynthetic characteristics of winter wheat seedling and the relationship between photosynthetic rate and influence factors under different soil droughts were analyzed. The results showed that the content of chlorophyll and photosynthetic rate were decreased with soil water decreasing. The regression model of photosynthetic rate of winter wheat seedling with influence factors was formed.
