摘　　要： 以花生 (Arachishypogaea) 种子为材料 ,探讨了不同活力花生种子在发育中合成与积累贮藏蛋白的能力 ,在萌发中贮藏蛋白的降解动员能力 ,以及肽键内切酶 (主要的蛋白酶 )活性的变化 ,阐明这些生物活动反映种子活力高低 .同时还研究了在蛋白合成中起重要作用的rRNA ,阐明它的完整性也随种子活力而变化 . The complex vigour index is closely correlated with synthesis of storage protein in cotyledons during peanut seed development.The protein contents of high vigour seeds was high and that of medium or low vigour seeds was low.During germination of high vigour seeds,the activity of endopeptidase was higher and the degradation rate of the salt-soluble protein and arachin was faster than that of medium vigour seeds.rRNA is important for the synthesis of proteins. During seed deterioration, the degradation of rRNA species could be detected.Its integrity changed in accordance with seed vigour.
