摘要
以高诱1号诱导的不同基因型玉米单倍体为材料,在3~5叶期用不同浓度的甲基胺草磷溶液进行滴心处理,研究甲基胺草磷加倍单倍体的效果。结果表明:不同浓度的甲基胺草磷溶液的加倍效率存在一定差异,100μmol/L的甲基胺草磷溶液处理的单倍体加倍效率最高;不同遗传背景材料的加倍效果存在差异。
With the maize haploids of different genotypes induced by Gaoyou 1 as materials, different concentrations of amiprophos - methyl were used to treat their growing points during three - leaf to five - leaf stage to analyze the doubling effects. The results showed that the doubling efficiency of different concentrations of amiprophos -methyl had certain differences and 100 μmoL/L amiprophos -methyl had the best effect. The materials with different genetic backgrounds had different doubling effects.
