| 摘 要： | 利用高能粒子处理紫花苜蓿干种子,观测龙牧803苜蓿M2代在秋末冬初低温条件下叶片游离脯氨酸含量(Pro)、过氧化物歧化酶活性(SOD)、可溶性糖含量(LSSC)、叶绿素a含量(Chla)和叶绿素b含量(Chlb)。结果表明, 高能粒子处理在秋末冬初低温条件下M2代的抗寒性指标显著高于对照(P<0.05);随着辐照剂量的增大,M2代叶片Pro含量、SOD酶活性、LSSC含量、Chl含量明显递减。低剂量辐照下M2代获得的抗寒性强于高剂量辐照,由此确定苜蓿的最佳高能粒子辐照剂量为145 Gy,其次是195 Gy。

| Abstract: | The seeds of Longmu No.803 alfalfa were pre-treated in a mixed high-energy particle field.The effect of M2 on Longmu No.803 alfalfa subjected to low temperature treatment between autumn and winter were studied,including monitoring the leaf for free proline content,SOD activity,LSSC,Chla and Chlb contents after treatment with different radiant dosages.The mixed high-energy particle field significantly(P<0.05) increased the cold tolerance of M2 compared with the control.With increasing radiant dosage,the prol... |
