摘　　要：Abstract Melatonin （N-acetyi-5-methoxytryptamine） is a well-known animal hormone, which is synthesized and secreted by pineal gland and takes part in the regulation of circadian rhythm in animals. At present it has been observed that melatonin is widely existed in higher plants while there have no enough studies on functions of melatonin in plants. Researches have already indicated that the possible functions of melatonin in plants include regulating photoperiod, participating in growth regulation, clearing active oxygen, and promoting activity of antioxidase. General reviews upon functions of melatonin in plants are made upon experiments in recent years. We fo-cus on the demonstrated and predicted biological functions of melatonin in plants to bring researchers up to date on this field. The weakness in present studies and the main research directions are also pointed out.褪黑素是一种广为人知的动物激素,在动物中由松果体合成与分泌,参与动物的昼夜节律的调节。现已发现褪黑素在高等植物中广泛存在,但是目前有关褪黑素在植物中的功能的研究还不是很多。已有的研究表明,褪黑素在植物中可能的作用有调节光周期、参与生长调节、清除活性氧、提高抗氧化酶活性等。根据近年的研究结果对植物中褪黑素的作用进行综述,重点阐述已经发现的褪黑素在植物上的功能作用,对其潜在生理功能进行了预测,并指出了目前研究中的不足,突出需要重点研究的方向。
