 This research paper investigated the effects of melatonin on the growth of the plant species Phoebe Sheary, Hemsil. Gamble under drought conditions. It found that melatonin can reduce the negative effects of drought stress on the plant by increasing its tolerance to drought, as well as reducing oxidative damage caused by the stress. Additionally, it was observed that melatonin had a positive effect on the plant's antioxidant enzymes, which are responsible for neutralizing free radicals and preventing cellular damage. Furthermore, the study showed that melatonin also affected the plant's hormone levels, such as abscissic acid and jasmonic acid, which are involved in regulating the plant's response to stress. Overall, this research provides evidence that melatonin can be used to improve the survival rate of plants exposed to drought conditions.
