摘要： 通过定期挖株调查，对豫芝11号夏播芝麻生长动态进行了研究 。研究结果表明豫芝11号夏播芝麻光合产物积累速度以播后47d－62d最快,平均每公顷每天为103.13kg。主根长度及支根数量在62d以前增加较快，62d以后增长稳定，但重量不断增加。茎杆增长高峰、叶面积系数最大值均出现在播后47d —62d，62d后增长缓慢。77d以后45%以上光合产物都分配于生殖生长上，单株粒重、千粒重也迅速增长。千粒重、蒴果重均与芝麻产量密切相关。收获时经济系数为27.54%。

Abstract: Through regular studies of Sesame variety Henan 11. The result suggested that the best speed of photosynthetic matler accumulation is in 47ds－62ds, 103.13kg per day per hm2 .The creasing of length of chief root and quantity of branch root is much better before 62ds.The best leaf area inder is in 47ds--62ds. Seed weight of each plant 1000--seed weight grow much better after 77ds. Economic coefficiency get 27.54%.
