摘要: 对6个二倍体西瓜品种进行了提高秋水仙素诱导率的试验研究。结果表明,剥去生长点外幼叶后用秋水仙素溶液滴苗、涂抹处理,其变异株率分别为52%和61%;浸芽处理的变异株率为39.1%。以上处理方法显著优于并可代替常规的滴苗、涂抹和浸种方法。

Abstract: The experiments for increasing the induction frequency of tetraploid watermelon were made with three methods of colchicine treatment, with 6 diploid varieties of watermelon as materials. When the small leaves were peeled off and the bare growth tips were treated with colchicine drops, the variation frequency (the number of variated plants/the number of suvival plants) was 52%, and the treatment efficiency (the number of variated plants/the number of treated plants) was 30.4%. When the bare growth tips were daubed with Lanolin paste mixed with colchicine, the variation frequency and treatment efficiency were 61% and 29.4%, respectively. When the growth tips were covered with small leaves they were immersedinto colchicine solution, the variation frequency and treatment efficiency were 39.1 % and 23.7%, respectively. The mentioned methods were much better than the conventional methods.
