水稻高光效种质资源筛选试验

Screening of Rice Germplasm with High Photosynthetic Efficiency

以12个品种的水稻为材料,进行高光效水稻品种的筛选试验,测定了叶绿素含量、可溶性蛋白含量、光合速率和光合功能期等相关生理生化指标。结果表明:不同品种水稻在光合速率、光合功能期和可溶性蛋白含量方面均存在差异;武育粳1号、杨育粳1号、杨粳4227光合速率、光合功能期和可溶性蛋白含量显著优于其他品种;武育粳1号、杨育粳1号的叶绿素含量较高。武育粳1号、杨育粳1号、杨粳4227是较优的高光效品种。

12 rice varieties were used as materials to screen out the rice germplasm with the high photosynthetic efficiency,the physiological and biochemical indexes of rice,including chlorophyll content,soluble protein content,photosynthetic rate and function duration were measured.The results showed that there were significant differences in soluble protein content,photosynthetic rate and function duration among different varieties of rice.Soluble protein content,photosynthetic rate and function duration of Wuyujing 1,Yangyujing 1 and Yangjing 4227 were significantly higher than those of other varieties.Moreover,chlorophyll content in Wuyujing 1 and Yangyujing 1 were also higher than that of other varieties.These results indicated that Wuyujing 1,Yangyujing 1 and Yangjing 4227 were superior rice varieties with high photosynthetic efficiency.
