| 摘 要： | The biosynthetic time and accumulations of A-, B-, and C-type glutenin subunits in 7 winter wheat cultivars with different quality （strong, medium, weak gluten） were analyzed by SDS-PAGE. The results showed that no glutenin subunit was observed within 8 d after anthesis. Parts or all A-, B-, and C-type subunits appeared around day 12 in different cultivars. Other A-, B-, and C-type subunits appeared gradually. The accumulation of A-, B-, and C-type subunits fluctuated before maturity. The results of analysis of correlation between the ratios of A/T （total content of glutenin subunits）, A/C, AJ （B＋C）, （A＋B）/C, and （A＋B）/T and SDS-sedimentation value suggested that they were more significant. The negative correlation between the ratio of （B＋C）/T and SDS-sedimentation value was more significant, and the correlations between the ratio C/T and the SDS-sedimentation value were significantly negative.

| Abstract: | The biosynthetic time and accumulations of A-, B-, and C-type glutenin subunits in 7 winter wheat cultivars with different quality (strong, medium, weak gluten) were analyzed by SDS-PAGE. The results showed that no glutenin subunit was observed within 8 d after anthesis. Parts or all A-, B-, and C-type subunits appeared around day 12 in different cultivars. Other A-, B-, and C-type subunits appeared gradually. The accumulation of A-, B-, and C-type subunits fluctuated before maturity. The results of analysis of correlation between the ratios of A/T (total content of glutenin subunits), A/C, A/ (B+C), (A+B)/C, and (A+B)/T and SDS-sedimentation value suggested that they were more significant. The negative correlation between the ratio of (B+C)/T and SDS-sedimentation value was more significant, and the correlations between the ratio C/T and the SDS-sedimentation value were significantly negative. |
