| Zusammenfassung: | Copyright © 2022 Elsevier Masson SAS. All rights reserved. This study explored the repair effect of Selenium nanoparticles (Se-NPs) on tomato under the stress of Penthiopyrad (Pen), and expected to select out the optimal concentration and the application time of Se-NPs, to maximize the repair effect without causing phytotoxicity. The results showed that Pen induced severe oxidative stress on tomato and inhibited the growth and flavor quality of fruit. Compared with the control, the application of 1 mg/L Se-NPs at the immature green stage significantly improved the antioxidant capacity of tomato to reduce the MDA content. Besides, the plant hormones were synthesized normally, the contents of soluble sugars, volatile compounds and nutrients were increased, and the contents of organic acids were decreased in the 1 mg/L Se-NPs + Pen treatment group, which finally repaired the fruit flavor and quality. Therefore, the application of 1 mg/L Se-NPs and at the immature green stage represented a promising strategy for repairing the inhibitory effect of Pen on tomato fruit growth and flavor quality |
