摘要
研究了3个不同熟期甘蓝品种幼苗期叶片蛋白质含量、可溶性糖含量、还原糖含量和叶绿素含量的变化。试验结果表明,3种甘蓝幼苗期蛋白质含量和叶绿素含量总体上都呈上升的趋势。可溶性糖含量都表现为在幼苗期的前3周逐渐升高并在第3周达到最高值,在第4周显著降低后又逐渐升高。还原糖含量多呈现无规律的波动性变化,但是还原糖含量的值都显著低于可溶性糖含量。
The changes of content of soluble protein soluble sugar reducing sugar and chlorophyll in leaves in seedling period were studied in 3 cabbage varifies. The results showed that the content of soluble protein and chlorophyll increased. The content of soluble sugar increased gradually in the first three weeks and got the top value at the third week, and it increased again after the decreasing at the forth week. The content reducing sugar displayed changes without regularity but its value was much lower than soluble sugar.
