Abstract: Melatonin is a small molecule indolamine hormone that widely exists in plants,and the studies have already clarified its synthetic pathway,catabolism and physiological functions. Melatonin can act as a signaling molecule to regulate plant circadian rhythms,seed germination,root and flower development,and also help to enhance the resistance of plants to various stresses. In this paper,the physiological functions of melatonin in regulating growth and development of herbaceous plants were summarized up,and its regulatory effects in response to abiotic and biotic stresses were particularly focused on. Additionally,functional study on melatonin in growth,development and stress resistance,as well as its application in stress resistance breeding in forage species were prospected. This review is expected to provide insight into improving the stress resistance,yield and quality enhancement of forage plants by using melatonin.

摘要: 褪黑素是一种广泛存在于植物体内的小分子吲哚胺类激素,现有研究已明确其合成途径、分解代谢和生理功能。褪黑素作为信号分子可调节植物昼夜节律、种子萌发、根和花发育,还有利于增强植物对各种逆境胁迫的抵御能力。本文总结了褪黑素调控草类植物生长发育的生理功能,重点阐述了褪黑素在草类植物非生物胁迫和生物胁迫响应中的调控作用,并对其在草类植物生长发育与抗逆性功能研究以及在抗逆育种中的应用前景进行了展望,以期为利用褪黑素提高草类植物抗逆性、提升牧草产量和品质提供参考依据。
