研究了冬小麦幼苗在春化过程中过氧化物酶同工酶谱、过氧化物酶活性和可溶性蛋白质含量的变化。在冬小麦春化过程的中期,过氧化物酶同工酶谱存在着较显著的变化,第二条主要谱带逐渐减弱和接近消失,靠近正极的第四条主要酶带有所加强。而舂小麦正相反,第四条及第五条酶带都因春化处理而减弱。同时观察到春化21天以后冬小麦幼苗可溶性蛋白质含量迅速增加。 The changes of peroxidase isozyme, peroxidase and soluble protein contents of winter wheat seedlings during vernalization were studied. During the vernalization of winter wheat, there was a significant change in the isoenzyme pattern of peroxidase. The second major band gradually weakened and disappeared, and the fourth major enzyme near the positive pole was strengthened. On the contrary, in wheat, the fourth and fifth bands were weakened by vernalization. At the same time, the soluble protein content of winter wheat seedlings increased rapidly after 21 days of vernalization.
