【摘要】 用γ射线及甲基磺酸乙酯（ＥＭＳ）诱变三叶木通种芽，探讨其诱变技术及变异规律。结果表明：γ射线与ＥＭＳ综合处理三叶木通种芽，能产生早实变异，童期１３个月，比对照缩短１２个月以上；也能产生早熟变异，果实生长期３．５个月，　比对照缩短２个月以上　；　熟期变异出现频率平均为　　０．１３％，变幅０～０．２４８％；γ射线诱变剂量既是诱变苗成活率极显著的影响因素，又是成熟期变异率显著的影响因素；３　０００伦琴剂量的Ａ２，变异频率显著地高于５　１００伦琴的Ａ３及９００伦琴的Ａ１，诱变成活率极显著地高于Ａ３，低于Ａ１。早实变异株雄性败育，叶片生长速度减慢。更多还原

【Abstract】 A mutagenic technology of akebia trifolat a was studied.The results indicated that it can produce mutant of the mature p eriod and its frequency reached 0.13% mutation after the seed bud of akebia t rifoliata was induced by γ ray and ethyl methane sulphonate.The growth stage before flower was thirteen month of the early-fruit mutation and its first frui t stage was one year earlier than same seeding.The fruit growth stage of the ear ly-maturing mutation was 3.5 month and reductiver 2 month than same seeding The leaf growth speed was alow and its male flower was sterility of the mutant.The m utagenic dose of gamma ray was great affecting factor on both the mutation freq uency and the survival rate of the mutagenic seeding.The 3 000 roentgen dose was suitable and its mutagenic efficiency was better.更多还原
