| 摘 要： | 引进19份苜蓿Medicago sativa品种进行了实验室耐盐试剂试验和不同盐碱含量的田间出苗试验。结果可以看出,在盐胁迫下的发芽势和发芽率强的品种有西部巨人、WL232、32IQ、大富豪;WL232、阿尔冈金及阿尔冈金BT、费纳尔、32IQ这5个品种对单盐毒害的耐性强;田间试验中,西部巨人、WL324、阿尔冈金BT、亮苜2号的平均株数与对照阿尔冈金差异不显著。室内盐离子胁迫下的相对发芽率与盐碱地田间调查株数呈显著正相关。最终筛选出3个耐盐碱性强的品种,分别是西部巨人、亮苜2号、WL324。

| Abstract: | The salt-alkali tolerance of 19 alfalfa varieties were studied in laboratory and a field.The lab experiment indicated the germination energy and germination rates of West-Giant,WL232,32IQ,and DAFUHAO were higher than others,tolerance to single salt of WL232,Aergang-Jin,Aergang-Jin BT,FEINAER and 32IQ was greater than others.The field experiment showed there were no differences between plants number of each variety.Additionally,germination rate in laboratory was positive correlated with plant number in field... |
