| 摘 要： | 运用灰色关联度原理对紫花苜蓿中苜2号114个单株中选择出的50个总重较高的单株再生性能进行了评价。结果表明,与单株再生总重密切相关的再生性状中,以再生分枝数对再生总重影响最大,其次是再生株高、再生强度、再生速度,再生单茎重对再生总重影响最小。同时,对单株的再生性能进行了综合评价,选择出ZM36、ZM12、ZM43、ZM50、ZM13、ZM46、ZM44、ZM42、ZM3、ZM6、ZM2、ZM10、ZM20、ZM4、ZM9、ZM18、ZM37、ZM14、ZM47、ZM7共20个再生性能较好的单株材料。

| Abstract: | Fifty alfalfa single plants with higher yield selected from 114 Zhongmu No.2 single plants were evaluated by using grey relational degree.The results indicate that the regrowth characteristics closely connected with the regrowth yield,regrowth number of shoots had the highest effect on the total regrowth amount.Dry weight,regrowth height,intesity of regrowth,regrowth rate were secondary,but regrowth stem weight per shoot had a little effect on regrowth yield.Regrowth characteristics of single plant were comprehensive evaluated and ZM36,ZM12,ZM43,ZM50,ZM13,ZM46,ZM44,ZM42,ZM3,ZM6,ZM2,ZM10,ZM20,ZM4,ZM9,ZM18,ZM37,ZM14,ZM47,ZM7 with better regrowth characteristics had been selected. |
