低能N+离子束注入诱导的醇溶蛋白变异与高分子量谷蛋白亚基的变异有相似的规律。

Under two levels of earing fertilization (N0 and N2), compared with 25℃ treatment, heat stress (35℃) accelerated the grain filling and resulted in less grain weight, and also reduced the two glutelin subunits content of both fertilization treatments 12.1% and 5.7% respectively, and reduced the prolamin content of them 6.7% and 4.9% respectively. Simultaneously, the polypeptides above 57 kD was increased 18.8% and 11.7% respectively, and grain crude protein content was also increased 0.56% and 0.35% respectively.
