【摘要】 本试验用根冠离体活细胞测定法和苗期浸根法测定了不同抗性的十二个菜豆(Phaseolus vulgaris L.)品种对大丽花轮枝孢菌(Verticillium dahliae kleb)毒素的敏感性,两者的结果基本一致.经统计分析,这两种结果呈极显著正相关.试验结果还表明:根冠活细胞测定法比苗期浸根法快速,简便,准确,可靠,是进行菜豆抗病性鉴定和选育抗病品种等研究的一种比较理想的手段.更多还原

【Abstract】 In order to determin sensibility of twelve varieties of Kindey bean (Phaseolus Vulgarly L. ) to toxin of Verticillium dahliae Kleb the methods of both analysing living cells of roots cap in vivo and dipping roots -at seedling stage were used. The results of two methods were almost same, and the two methods were significantly correlated with each other. The test results indicated that the method of analysing living cells of root cap was faster, simpler. more accurate and more reliable than the method of dipping roots at seedling stage, therefore, the former was a ideal way to idertify the disease resistance of kidney bean and to breed varieties resistant to diseses by selection更多还原
