硼对甘蓝型油菜不同品种细胞壁盐溶蛋白质含量的影响

水培条件下，以典型的硼高效和硼低效甘蓝型油菜品种为试材，研究硼对细胞壁盐溶蛋白质含量的影响。结果表明，硼对油菜各器官细胞壁中的盐溶蛋白质含量均有不同程度的影响。缺硼时，高效品种和低效品种根系和上部茎细胞壁盐溶蛋白质含量均下降，但硼低效品种下降幅度大于硼高效品种，硼高效品种薹期供硼与缺硼处理间差异不显著。上部叶片细胞壁盐溶蛋白质含量，硼低效品种缺硼时显著下降，硼高效品种则显著升高，薹期高效品种供硼与缺硼处理间差异不显著。两品种下部叶片缺硼时的变化趋势与上部叶片相同，但不同时期的差异均不显著。

Effect of boron on the LiCl extracted protein content in cell wall of different rape cultivars

Under the condition of solution culture, the effect of boron on the LiCl extracted protein content in cell wall of a typical B effective and a B ineffective rape ( Brassica napus L) cultivars were studied. The results showed that B starvation resulted in significant decreases in LiCl extracted protein content in cell wall of root and upper stem of both cultivars. But the decreases were greater in the B ineffective cultivar. The protein content of upper leaf decreased significantly in B effective cultivar and increased significantly in B ineffective cultivar under B deficient condition. The protein content in lower leaf had the same tendency as that in upper leaf, but the difference between the treatments was not significant. B has no significant effect on the proten content at bolting stage of B effective cultivar.
