摘要：

Pot and field experiments were conducted to examine the effect of boron on the yield and quality of different rape genotypes and to identify cultivar variation in some physiological responses to boron. B fertiliser can significantly increase the yields of both traditional and high-quality rape. Significant differences in yield response to boron application were found between cultivars. High quality varieties were more sensitive to boron deficiency than a traditional variety. Application of boron increased plant height, net photosynthetic rate, activity of nitrate reductase (NRA) and dry-weight yield, and decreased the contents of erucic acid and glucosinolate in both traditional and high-quality rape varieties. Boron plays a positive role in keeping the stability of the good characteristics of high quality cultivars.
