چکیده
This study examined the antioxidant defense capacity of various cabbage species in response to salt stress. Seedlings were exposed to salinity levels of 0, 50, 100, and 150 mM for eight days. Results indicated that germination rates, fresh weight, and dry weight decreased with increasing salinity. Notably, Brussels sprouts maintained the highest germination percentage, even at 150 mM. Interestingly, both root and seedling lengths increased under salt stress across all cultivars. Gene expression analysis showed a significant upregulation (P<0.05) of glutathione reductase (GR) and ascorbate peroxidase (APX) activities under salinity. Other biological indices, including root and shoot growth, also exhibited increases, reflecting adaptive responses to salt tolerance. Although germination rates declined with higher salinity, the expression of the analyzed antioxidant genes rose by approximately 41.09% at 100 mM but dropped by 13.97% at 150 mM across all cultivars. Overall, the findings underscore the varied responses of Brassica cultivars to salt stress, with Brussels sprouts demonstrating notable resilience and enhanced antioxidant gene expression under high salinity conditions.
