Effects of salt stress on antioxidant oxidase activity of Hosta plantaginea seedlings
Received date: 2024-08-03
Online published: 2025-04-14
To explore the effect of salt stress on antioxidant oxidase activity of Hosta plantaginea seedlings, Hosta plantaginea seedlings were taken as experimental materials. After 14 days of pot culture, water treatment was used as the control, the seedlings were treated with salt stress with different concentrations of NaCl solution (0.25%,0.50% and 0.75%), and their activity of CAT, SOD, POD and APX. The results showed that the activities of CAT, SOD and POD of Hosta plantaginea seedlings increased with the increase of salt stress concentration; the activity of APX decreased. To sum up, the seedlings of Hosta plantaginea mainly eliminated excess harmful substances in the body by increasing the activities of CAT, SOD and POD, decreased APX activity so as to resist salt stress.
Key words: Hosta plantaginea seedlings; salt stress; catalase; ascorbate peroxidase
