高油酸油菜营养丰富,具有较高的栽培与应用价值。本试验以一组高油酸近等基因系油菜为材料,对其不同时期的生理生化特性进行了研究,结果如下:高油酸材料可溶性糖含量在整个生长期较低油酸材料高,而可溶性蛋白含量及叶绿素含量均在营养生长期低于低油酸材料,在生殖生长期高于低油酸材料。POD活性在营养生长期与低油酸材料无显著差异,在生殖生长期高于低油酸材料。SOD活性在蕾薹期以前均高于低油酸材料,在生殖生长期低于低油酸材料。整体而言,高、低油酸材料可溶性糖含量、可溶性蛋白含量及叶绿素含量在整个生育期均呈现先升后降的趋势,并在蕾薹期达最大值。POD活性则在营养生长期较低而在花期与角...

Rapeseed of high oleic acid content (HOAC) is rich in nutrients and has high cultivation and application values. In this study, a group of HOAC near-isogenic lines rapeseeds were used as materials for the analysis of the physiological and biochemical characteristics at different developmental stages. The results showed that the soluble sugar content of HOAC rapeseed was higher than that of low oleic acid content (LOAC) rapeseed during the whole growth period, the soluble protein and chlorophyll contents were lower than those of LOAC rapeseed in vegetative growth stage, and higher than that of ...
