| 摘 要： | 转Bt基因抗虫棉在沙培试验中对卡那霉素不同浓度的反应进行了检测。结果表明，浓度为4000mg/L的卡那霉素液对非抗虫棉最为敏感，反应率为100%，而转Bt基因抗虫棉均无反应。说明棉花室内抗卡那霉素反应能够准确检测转Bt基因抗虫棉纯度，可以作为一种快速、准确、简便的室内检测转Bt基因抗虫棉的方法。同时，不同浓度的卡那霉素液对棉苗胚轴、鲜重均有一定的影响。

| Abstract: | A simple,cheap,and efficient technique for transgenic Bt cotton using k anamycin as an indirect identification marker in the laborotary is tested.The re sult showed that kanamycin could be used in the laborotary to test whether or no t a plant is resistant.Seed of transgenic Bt cotton were cultured on sand bed co ntaining 4000 mg/L kanamycin solution for six days.The cotyledons of resistant v a rieties remained normal green color,whilst these of the commercial varieties all turned yellow.This technique is especially usful for the purity test of transge nic Bt cotton before the seed is sold. Meanwhile,the hypocotyls and fresh weigh of the cotton seedling were affected by the kanamycin in some degree. |
