为了创新蓖麻的种质资源,以通篦5号为材料,用0,0.02,0.03,0.04,0.05,0.06 mol /L 的 EMS 溶液处理去壳的蓖麻种子,处理时间分别设定4,8,12 h,研究不同处理浓度和时间组合对蓖麻种子发芽率和根长的影响。结果表明:用0.04 mol /L 的 EMS 溶液处理4 h,蓖麻种子的相对发芽率为49%,为半致死剂量处理组合,平均主根长10.45 mm。随着处理浓度的增加和处理时间的延长,蓖麻种子的相对发芽率和平均根长均表现下降趋势,处理浓度到0.06 mol /L 时,蓖麻种子完全不能萌发;对10个突变体 ISSR 分子标记分析发现,M2发生了分子水平的变异,引物 P91扩增出的多态性位点达13个。
為瞭創新蓖痳的種質資源,以通篦5號為材料,用0,0.02,0.03,0.04,0.05,0.06 mol /L 的 EMS 溶液處理去殼的蓖痳種子,處理時間分彆設定4,8,12 h,研究不同處理濃度和時間組閤對蓖痳種子髮芽率和根長的影響。結果錶明:用0.04 mol /L 的 EMS 溶液處理4 h,蓖痳種子的相對髮芽率為49%,為半緻死劑量處理組閤,平均主根長10.45 mm。隨著處理濃度的增加和處理時間的延長,蓖痳種子的相對髮芽率和平均根長均錶現下降趨勢,處理濃度到0.06 mol /L 時,蓖痳種子完全不能萌髮;對10箇突變體 ISSR 分子標記分析髮現,M2髮生瞭分子水平的變異,引物 P91擴增齣的多態性位點達13箇。

In order to innovate castor germplasm,hulled castor seeds were treated with EMS at 6 levels (0, 0.02,0.03,0.04,0.05,0.06 mol /L)and different time(4,8,1 2 h),The results showed that lethal concentration 50 was at 0.04 mol /L and 4 h,the average taproot length was 1 0.45 mm,and the concentration of EMS reached to 0.06 mol /L,the seeds could not germinate completely.With the increasing of treatment time and concentration,cas-tor seed germination rate and average relative root length showed a downward trend;ISSR molecular marker analysis showed that DNA variation existed in M2 by EMS.The primer P91 detected 1 3 variation loci.
