硼对甘蓝型油菜蛋白质的影响

利用比色法和聚丙烯凝胶电泳法分析了不同硼营养状况下甘蓝型油菜的幼苗叶片及开花期花药内可溶性蛋白质含量及组分的变化。结果表明,缺硼或硼过量部会造成幼苗叶片及花药内蛋白质含量显著下降;从电泳图谱中也可看出,可溶性蛋白质的组分也发生了变化。不适当供硼(缺硼或硼过量)幼苗叶片及花药内所测的大部分蛋白质含量减少,有个别的蛋白质增加或缺失。

EFFECT OF BORON ON PROTEIN CONCENTRATION AND COMPONENT IN BRASSICA NAPUS L.

The changes of soluble protein concentration and composition in leaves and anthers of rape (Brassica napus L.) plants under the different boron nutritional conditions were studied with nutrient solution and soil culture. The results showed that under boron stress (low or high boron) the protein content in leaves and anthers was decreased markedly. The component of soluble protein in the same parts of the plants was also changed. Under the boron stress the content of the most measured protiens was decreased, the others were increased or absent.
