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. Six diploid watermelon cultivars were studied to improve the induction rate of colchicine.The results showed that after removing young leaves outside the growing point with colchicine solution drip seedling and smearing treatment, the rate of mutant strains was 52% And 61%, respectively, and the rate of mutagenic plants was 39.1% .The above treatment methods were significantly better than those of conventional drip irrigation, smear and soaking methods.
