褪黑素在园艺产品保鲜中的研究进展

Research progress of melatonin in preservation of horticultural products

褪黑素在植物中具有调控生长发育、提高抗逆性和延缓衰老等生理功能.随着褪黑素在植物领域的相关研究日益增多,人们对褪黑素在蔬菜、水果和切花等鲜活园艺产品保鲜中的作用及其应用研究也陆续有文献报道.简要述评了褪黑素在园艺产品保鲜中清除细胞内自由基、保持细胞膜完整、调控果实成熟、延缓叶片衰老以及提高抗逆性等主要生理作用及其应用前景.

Melatonin has many physiological functions in plants,such as regulating growth and development,improving anti-reversibility and delaying senescence.With the increasing researches on melatonin,such as in the field of plants,in recent years,it has been also successively reported on the roles and applications of melatonin in the preservation of fresh horticultural products,such as vegetables,fruits and cut flowers.This paper briefly reviewed the research progress in main physiological roles of melatonin,such as in scavenging cell free radicals,maintaining cell membrane integrity,regulating fruit ripening,delaying leaf senescence,and increasing stress resistance,towards preserving horticultural products.Moreover,its application prospects in this field were also forecasted.
