本文报道了元帅苹果在果实发育及贮藏过程中蛋白质含量的变化规律,探讨了种子蛋白质与果实呼吸强度间的关系.结果表明,果实蛋白质含量随果实的膨大而增长,在采收前果皮和果肉含量明显下降,种子含量虽有降低但仍保持较高水平.在果实贮藏过程中,种子蛋白质含量变化与呼吸强度无直接关系,但在呼吸跃变期出现有突然升高现象. This paper reports the variation of protein content of Marshmallow apples during fruit development and storage and discusses the relationship between the seed protein and fruit respiration rate.The results showed that the fruit protein content increased with the fruit enlargement, But the seed content remained high even though the seed content decreased.During the storage of fruit, the change of seed protein content was not directly related to the respiration intensity, but suddenly appeared in the transitional period of respiration.
