黄皮种子发育晚期 ,胚内核酸、蛋白质合成能力增强 ,而花生胚的核酸、蛋白质合成能力在发育晚期则呈下降趋势。黄皮胚的发育在达到生理成熟后维持着活跃的生理代谢并转入萌发状态 ;而花生胚的代谢活性逐步降低并转入生理静止状态。脱水处理引起生理成熟期黄皮胚核酸、蛋白质合成能力急剧下降 ,核酸水解酶活性增强。不同程度脱水的黄皮胚吸胀 2 4 h,核酸、蛋白质的合成能力随脱水程度的加深而降低 ;生物大分子代谢能力的变化是顽拗性黄皮种子脱水敏感性的分子基础。
At the late stage of seed development, the ability of nucleic acid and protein synthesis in embryo was enhanced, while the synthesis ability of nucleic acid and protein in peanut embryo decreased at the late stage of development. After reaching physiological maturity, the development of the yellow skin embryo maintained an active physiological metabolism and transferred to the germination state; while the metabolic activity of the peanut embryo gradually decreased and turned into a physiological state of rest. Dehydration treatment resulted in a sharp decline in nucleic acid and protein synthesis capacity of Huangmaoderma in physiological maturity, and increased activity of nucleic acid hydrolase. The different degrees of dehydration of Huangpi embryos imbalance 2 4 h, nucleic acid, protein synthesis ability with the degree of dehydration deepened and reduced; changes in biological macromolecules metabolic recalcitrant yellow seed dehydration sensitivity of the molecular basis.
