摘要
The accumulation of protein fractions was analyzed on developing and mature wheat grains of three cultivars differing in protein content and baking quality. There was a slight difference in the accumulation of cytoplasmic proteins in the cultivars used. The high yield but low protein cultivar showed a consistent decline of protein content during grain filling but the high - protein cultivars increased their psotein contant after 25 days post-anthcsis. The accumulation of storage proteins was different from that of cytoplasmic protein, and there were also cultivar variations. However, all cultivars reached their, maximum-synthesizing capacity for storage proteins at maturity. The relationship between the protein fractions or their ratio and baking quality was also discussed.
