AI Article Synopsis
- Improper use of nicosulfuron (NSF) can harm plants while controlling weeds, prompting a study on how melatonin (MT) might help alleviate this toxicity in sweet corn seedlings.
- The research showed that adding MT improved growth parameters and increased chlorophyll content, photosynthetic rates, and stomatal conductance, while reducing harmful compounds associated with stress.
- Additionally, MT boosted the activity of beneficial enzymes, and blocking certain processes diminished MT's positive effects, suggesting that MT may effectively counteract NSF's negative impacts on plant health.
Article Abstract
Improper use of nicosulfuron (NSF) may induce harmful effects on plants during weed control. Melatonin (MT) regulates photosynthetic and physiological processes in plants. This study aimed to explore the effects of MT on alleviating NSF toxicity by measuring the growth parameters, photosynthetic capacity, and antioxidative responses in sweet corn seedlings. Compared to NSF alone, exogenous MT increased chlorophyll content, transpiration rate, net photosynthetic rate, stomatal conductance, and maximum efficiency of PSII photochemistry, while reduced malondialdehyde, hydrogen peroxide, superoxide anion radical, and proline contents. Moreover, MT also increased the activity of ascorbate peroxidase and the expression levels of , , , and . The inhibition of -chlorophenylalanine inhibited the positive effects of MT on photosynthetic and physiological indexes. The results indicated that pretreatment with MT might effectively mitigate NSF toxicity in sweet corn seedlings.
