| 摘要: |
| 选择9个苜蓿品种的多叶单株进行了茎节扦插繁殖,对繁殖后不同苜蓿群体的生长速度、再生性、茎叶比、鲜干比、多叶数量百分率、多叶重量百分率、产量等多个性状进行了综合性能比较.结果表明,多叶枝、多叶节、三叶节扦插均表现出多叶性状,其多叶植株数量百分率和多叶数量百分率均无显著性差异;所有参试品种扦插多叶型苜蓿的多叶植株数量百分率均远大于亲本;皇冠、阿尔冈金2个品种的平均生长速度较快,而WL-252HQ和WL-232HQ 2个品种的平均生长速度较慢,苜蓿王、阿尔冈金、皇冠、WL-323、飞马5个苜蓿品种的二茬、三茬再生速度均较快,而WL-252HQ和WL-232HQ 2个苜蓿品种的再生速度最慢;飞马的平均多叶数量百分率极显著高于其他8个品种,其中阿尔冈金、皇冠、CW200较高,苜蓿王最低;飞马的茎叶比极显著低于其他品种,WL-252HQ、WL-323、CW200、皇冠、阿尔冈金5个品种间差异不显著,但均显著低于WL-232HQ;不同苜蓿品种间第1茬和第2茬产草量均有显著差异,其中飞马的产草量最高,WL-232HQ的最低;飞马的综合生产性能最好,阿尔冈金、皇冠较为理想,WL-232HQ的综合生产性能最差。 |

| Abstract: |
| The experiment was conducted to study nine plants in growth speed,regrowth speed,stem/ leaf,the plant multifoliate expression on leaf weight,the plant multifoliate expression on leaf quantity,yield from multifoliate alfalfa after cutting.The results showed that all plants from multifoliate branch,multifoliate burl,trifoliate burl after cutting expressed multifoliate trait,and there was no markedly difference between the percent of the plant multifoliate expression on leaf quantity and the percent of multifoliate plant;The than percent of the plant multifoliate expression on leaf that of female parent;The average growing speed of Pha ty of cutting mu bulous and Algo ltifoliate alfalfa was bigger was faster,but WL-252HQ and WL-232HQ grew slowly;The re-growing speed of Emperor,Algonguin,Phabulous, WL-323,Grandeur was faster,but WL-252HQ and WL-232HQ grew slowly;The percent of the plant multifoliate expression on leaf quantity of Grandeur was higher than that of the others,Phabulous,Algonguin and CW200 were higher, Emperor the lowest.The stem/leaf of Grandeur was the lowest,and there was no markedly difference between WL-252HQ,WL-323,CW200,Algonguin,Phabulous,and WL-232HQ was the highest.The yield of Grandeur was the highest,and WL-232HQ was the lowest.The comprehensive capability of Grandeur was the best,Algonguin and Phabulous better,WL-232HQ worst. |
