摘　　要：本试验分别于1992～1993和1993～1994年在浙江省桐庐县梅蓉村的缺硼砂性冲积土壤上进行，16个油菜品种对缺硼反应的差异显著，中油821和92－13系较耐缺硼，表现为在缺硼条件下有较高的植株存活率，相对株高、叶面积和较低的落叶数比率，成熟时的绝对产量和相对产量较高，施硼增产幅度小。而湘油11号和皖油324对缺硼反应敏感，在缺硼时表现出较低的植株存活率，相对株高、叶面积和较高的落叶数比率，施硼的增产效应十分显著。Two experiments were carried out on a boron-deficient alluvial sandy loam at Meilong,Tonglu county, Zhejiang Province, in 1992~ 1993 and 1993~ 1994. Significant differences were foundamong the sixteen rape cultivars. Of the test cultivars, Zhongyou 821 and 92-13 are the most B-efficientas they have higher survival rate of seedlings, plant height, leaf area and lower percentage senescent leavesat no boron treatment and show little response to boron application while Xiangyou 11 and Wanyou 324are the most susceptible to boron deficiency.
