| 摘 要： | 本试验研究了平阳霉素(Pinyangmycin)对小麦的诱变效应.用平阳毒素10μg/ml、30μg/ml 和50μg/ml浓度处理小麦种子,M1根长平均数分别为20.06cm、17.84cm和17.07cm,3种浓度平阳霉素处理均比0.3%EMS处理抑制根长的效应显著;平阳霉素10μg/ml、30μg/ml和50μg/ml 3种浓度处理的根数平均数分别为4.59、3.97和3.53.平阳霉素处理的根数平均数明显少于对照和0.3%EMS处理;平阳霉素10μg/ml、30μg/ml和50μg/ml 3种浓度处理的M1苗高平均数分别为7.39cm、6.93cm和6.69cm,比对照苗高有明显降低.平阳霉素10μg/ml、30μg/ml 和50μg/ml浓度处理,出苗率分别为73%、69%和66%,M1根尖细胞染色体畸变率分别为6.15%、7.31%和5.17%,M2突变率分别为2.25%、2.55%和3.83%;平阳霉素处理比对照和甲基磺酸乙酯(EMS)处理,对M1出苗率及根尖细胞染色体畸变率都有明显的影响,试验结果表明平阳霉素是一种具有较强诱变效应的新诱变剂.

| Abstract: | The mutagenic effect of Pingyangmycin on wheat was studied in this experiment and average root lengths of wheat plant treated by Pingyangmycin were 20 06cm,17 84cm and 17 07cm,respectively.lnhibiting effects on root length were stronger when treated by three concentration of Pingyangmycin than that with EMS treatment.Average root number of wheat treated by Pingyangmicin of 10μg/ml,30μg/ml and 50μg/ml were 4 59,3 97 and 3 53 respectively,obviously fewer than CK and 0 3% EMS treatment.M 1 seedling heights,were 7 39cm,6 93cm and 6 69cm when treated by Pingyangmycin of 10μg/ml,30μg/ml,50μg/ml,respctively,obviously lower than CK.Seedling emerging rates were 70%,69%,66%, when treated by Pingyangmycin of 10μg/ml, 30μg/ml,50μg/ml,respectively.Chromosomal aberration rates were 6 15%,7 36% and 5 18%, respectively.Mutation frequencies of M 2 were 2 25%,2 55% and 3 83%, respectively.The results indicate that Pingyangmycin has strong mutagenic effect and can be used as a new mutagenic agent. |
