不同活力玉米种子胚萌发过程中蛋白质的变化

CHANGES OF EMBRYO PROTEIN IN MAIZE SEEDS WITHDIFFERENT VIGOURS DURING GERMINATION

摘要:

从不同人工老化处理中筛选出3组分别代表不同活力的玉米种子。萌发期间，中、低活力种子胚蛋白的降解比高活力对照种子慢，萌发前期胚蛋白合成能力也较低。吸胀24 h，不同活力胚的蛋白合成能力差异显著，可以作为衡量种子活力的指标。

Abstract:

High, medium and low vigour maize (Zea mays L.) seeds were obtained fromdifferent aging treatments. The content of embryo storage proteins in high vigour seedsdeclined more rapidly than that in medium and low vigour seeds during germination.Protein synthesis in high vigour seeds at 24 hours after imbibition was higher than that inaging seeds.
