采用土培方法，研究了２个甘蓝型油菜硼低效品种和４个甘蓝型油菜硼高效品种对缺硼反应的差异。结果表明：高效品种叶色浅、生育期短、抽苔早，低效品种叶色深、生育期长、抽苔晚，生育期和抽苔日数与硼效率系数间的相关性达到极显著水平，可作为早期筛选甘蓝型油菜不同品种硼效率高低的参考指标；在轻度缺硼条件下，低效品种苗期长势较弱，硼含量较高，经济系数小，而高效品种长势较好，经济系数大；轻度缺硼时，不同硼效率品种茎中硼的相对含量均高于硼正常水平，其中，高效品种又比低效品种高，有利于硼的运转和再利用，提高硼的利用效率；缺硼对低效品种株高、单株总果数、千粒重影响大，而高效品种受影响较小；不同硼效率品种的生育进程不受硼水平的影响。
Using soil culture method, the effects of boron deficiency on two boron inefficient Brassica napus cultivars and four high efficient Brassica napus cultivars on boron deficiency were studied. The results showed that the leaf color of the high efficient cultivars was short, the growth period was short, the leaf color of the early and inefficient bolls was longer, the growth period was longer, the bolting days, bolting dates and the bolting efficiency coefficients were significantly correlated , Which can be used as a reference index for screening boron efficiency of different varieties of rapeseed in the early stage. Under the conditions of slight boron deficiency, the inefficient cultivars grew weak at seedling stage, had higher boron content and economic coefficient, And the economic coefficient is high. When boron is mildly deficient, the relative contents of boron in stems with different boron efficiency are higher than the normal levels of boron. Among them, high-efficiency varieties are higher than low-efficiency varieties, which is beneficial to the operation and reutilization of boron, Boron deficiency has a great effect on plant height, total number of fruit per plant and 1000-grain weight, while high efficiency cultivars are less affected; boron fertility is not affected by different boron efficiency.
