转 Bt基因棉中棉所 30第 I期 (1 998年 7月2 5～ 2 6日开花 )棉铃花后 1 0 d的体积和单铃重分别较轮回亲本中棉所 1 6增加 8.57%和 1 1 .88% ,表明其库强度较高 ;而第 II期 (8月 3～ 5日开花 )和第 III期 (8月 1 2～ 1 4日开花 )棉铃的早期 (铃龄 1 0 d前 )及各期棉铃的中后期 (铃龄 1 0 d后 )体积和单铃重均低于中棉所 1 6,并且其瘪子数随开花期推延快速增加 ,反映了该品种源器官供应能力的不足。中棉所 30棉铃纤维对同化产物的竞争力较强 ,每饱子纤维数、每饱子皮棉重、每铃皮棉重和衣分基本上极显著或显著高于中棉所 1 6,而铃壳和种子的物质积累减少 ,铃壳比例、饱子数、饱子重和子指降低 ,瘪子数上升
The volume and single boll weight on the first day of cotton bollworm 30 (flowered from July 25 to June 26, 1998) were respectively 8.57% and 8.57% higher than those of the recurrent parent cotton plants 1 1 .88%, indicating that its bank strength is higher; while the first phase (August 3 to 5 flowering) and the third phase (August 12 ~ 14 flowering) cotton boll early (ring age 10 days (Both before and after boll stage) and the boll weight of mid-and late-term bolls (bolls of 10 days old) were lower than that of cotton plants of Cummins 16, and their number of defoliation increased rapidly with the delay of flowering stage, Lack of ability. Cottonseed 30 cotton boll fiber is more competitive in assimilation products. The number of perignum, per lint weight, lint weight and lint percentage per lint are basically significantly higher or significantly higher than that of cotton in Central China The material accumulation in the shell and seeds decreased, the ratio of the shell to the shell, the number of full seeds, the number of full seeds and the number of fingers decreased,
