山西省小麦主栽品种光能转化特性研究

Studies on Photosynthetic Characteristics of Major Wheat Cultivars in Shanxi Province

山西是小麦的主要产区,了解该地区主栽小麦品种的光能转化特点,对进一步推广高光合特性的小麦品种具有指导作用。对山西16个冬小麦主栽品种的光合速率和气孔导度进行了对比分析。结果表明,不同品种间光能利用率存在较大差异,品种长6878和晋太170的光能利用率高,就光合特性来说是首选的推广品种。

Shanxi is very important for wheat production. It is useful information to understand photosynthetic characteristics of these cultivars for wheat breeding. 16 major cultivars were analyzed in photosynthetic rate and stomatal conductance of flag leaves in the area. The results showed that there were large differences in photosynthetic characteristics of different varieties. Chang 6878 and Jintai170 had high the light energy utilization rate, which was the preferred varieties to photosynthetic characteristics.
