摘要
用远缘杂交后代为材料,测定了不同叶型不同时期的叶绿素含量、光合强度。结果表明:在吐絮期前鸡脚叶叶片的叶绿素含量和光合作用强度均高于正常叶。而在吐絮期后正好相反。考查了不同叶型的单株结铃数、铃重、衣分、虫籽率和僵瓣率。试验结果表明:鸡脚叶对陆地棉产量没有不利影响;与正常叶比较,红铃虫为害的虫籽率和僵瓣率分别低32.7%和18.8%。
Determining different leaves kinds chlorophyl content and photosynthetic intensity in different stage by using distant crossing posterity as material. The result indicate chicken- paw leaves chlorophyl content and phothsyntheic intensity is higher than normal leaves before open boll stagee, chicken - paw leaves have no unfavourable effect to upland cotton production and pink bollworm in chicken- paw leaves less than the normal.
