| 摘 要： | 切花花瓣衰老过程中发生一系列生理生化变化,包括可溶性蛋白总量下降、糖含量的变化、乙烯大量合成、自由基增加等。文章从蛋白质和氨基酸代谢、糖代谢、内源激素、膜脂过氧化等方面对切花花瓣衰老的生理机制进行了综述,并对该领域未来的研究方向作了展望和分析。

| Abstract: | There are a series of physiological and biochemical changes in the senescence process of cut flower petals,including the decline of soluble protein content,changes of sugar content,synthesis of large quantity of ethylene,and increase of free radicals,etc.We reviewed the physiological mechanism of cut flower petals senescence from metabolism of protein and amino acid,metabolism of sugars,endogenous hormones and membrane lipid peroxidation.Future research direction was also discussed. |
