对转基因抗虫棉杂交种的光合生产及干物质分配研究表明，转基因抗虫棉杂交种Ｆ１代种有效叶面积显著增多，高效叶面积大，比叶重和净同化率高，群体发展较合理，光合生产率高。在干物质分配上以茎枝较多，经济器官居第二位，叶居第三位。在不同层次上表现为中上部叶干重较高和上部经济器官干重较高，因此在栽培应用时需加以调节，可进一步提高产量。
Studies on photosynthetic production and dry matter partitioning of transgenic Bt hybrid cotton showed that the effective leaf area of F1 hybrids of transgenic Bt cotton hybrids increased significantly, the area of high efficient leaf area was larger, the specific leaf weight and net assimilation rate were higher, and the population development was more reasonable , Photosynthetic productivity is high. On the distribution of dry matter to more stems, economic organs in second place, Ye Habitat third place. At different levels, the upper leaves have the highest dry weight and the higher dry weight of the upper economic organs. Therefore, the cultivation needs to be adjusted to further improve the yield.
