| 摘 要： | 用r射线对草原一号苜蓿进行诱变 ,其剂量为 2万伦、4万伦、6万伦、8万伦 ,设对照对M1代进行测定 ,结果表明 :植株自然高度 ,以剂量为 2万伦的最高 ,为 110 3cm ,单株分枝数以剂量为 6万伦的最高 ,是 11 6个 ,单株叶面积以剂量为 6万伦的最高 ,是 10 4 41cm2 ,产量是以剂量为 6万伦的最高 ,是 4 7kg/m2 ,植物含水量以剂量为 4万伦的最高 ,占鲜重的 6 0 % ,占干重的 15% ,需水程度以剂量为 2万伦的最高 ,是 1 11% ,自由水含量以 6万伦处理的最高 ,是 54% ,说明其具有生长速度快、产量高的生理基础。束缚水含量以剂量为 2万伦处理的最高 ,其次为 4万伦。若以产量为育种目标应选择 6万伦处理的材料 ,以抗性为育种目标应选择 2万伦处理的材料
