| 摘 要： | 通过对58份不同秋眠类型苜蓿品种再生性、持久性和产草量在呼和浩特的测定分析,结果表明:1)在全部参试材料与秋眠类型组中,苜蓿秋眠级和再生性正相关并达到极显著、显著水平;而在半秋眠类型组、非秋眠类型组中,苜蓿的再生性和秋眠级相关性很小。2)在全部参试材料、半秋眠类型组、非秋眠类型组中,首蓿的持久性与秋眠级负相关,但是在秋眠类型组中,首蓿秋眠级和持久性相关性很小。3)在全部参试材料、半秋眠类型组、非秋眠类型组中,苜蓿的产草量和秋眠级负相关;在秋眠类型组中,苜蓿的产草量和秋眠级正相关但不显著。 |

| Abstract: | In this paper, 58 varieties (lines) with various fall dormancy classes were measured and analysed in aspects of regrowth, persistence and yield in Huhhot. The result showed that;1)in all entries and fall dormancy groups, alfalfa fall dormancy was positively correlated with regrowth, but in semi-dormancy and non-dormancy group, alfalfa fall dormancy was not correlated with regrowth significantly ;2)in all entries and semi-fall dormancy group, alfalfa fall dormancy was negatively correlated with persistence, but in dormancy group, alfalfa fall dormancy was not correlated with regrowth significantly; 3) in all entries, semi-fall dormancy group and non-dormancy group, alfalfa fall dormancy was negatively correlated with yield, but in dormancy group, alfalfa fall dormancy was positively correlated with yield but not significantly. |
