The effect of potassium on flag leaf protein content and kernel quality as well as enzyme activity in wheat was investigated using wheat cultivar Yannong 15 with strong gluten potential.
利用强筋冬小麦品种烟农15研究了钾素对小麦旗叶蛋白质含量和籽粒品质及有关酶活性的影响。
The results indicated that the contents of soluble protein, DNA and RNA in flag leaf gradually reduced, but the activities of protease and nuclease gradually raised during senescence.
结果表明 ，小麦旗叶衰老过程中可溶性蛋白质含量、DNA和RNA含量逐渐下降 ，而蛋白酶和核酸酶活性逐渐升高。
Soluble protein in flag leaf, which implies senescence of flag leaf, tented to decline with the increase of nitrogen fertilization.
在氮素代谢方面，增施氮肥使小麦旗叶中硝酸还原酶活性增加，旗叶中可溶性蛋白含量降低，可明显延缓小麦叶片的衰老；
