【摘要】 为建立亚麻多倍体化学诱导技术体系,通过清水浸泡时间与秋水仙碱溶液浓度、处理温度、处理时间的比较试验,研究了外界因子对亚麻多倍体诱导形态变异率的影响。结果表明:亚麻多倍体诱导,以清水浸种16小时,转入0.16%的秋水仙碱溶液,在20℃条件下浸泡12小时为最佳,其成活率为36.07%,诱导率达到24.67%,则诱导成活率为8.9%。更多还原

【Abstract】 In order to establish the technical system of chemical inducement of the polyploid flax, major external factors of polyploid inducement of the flax seed, such as water dunk, colchicines concentration, temperature and working time were all studied in this paper. The results showed that the best inducing effect could be obtained under the conditions as follows: dunk by 16 hours, colchicines concentration 0.16%, temperature 20℃, working time by 12 hours. The survivor ratio was 36.07%. The inducement ratio was 24.67%. And the induced survivor ratio was 8.9%.更多还原
