MDA was found to have a highly significant negative correlation with SOD, chlorophyll a (Chla), chlorophyll b (Chlb), and total chlorophyll (Chl (a+b)) ( P < 0.01).

During salt-drought combined stress, when D1 was crossed with different salt concentrations compared to CK, plant height showed a decreasing trend with increasing soil salt concentration.
In contrast, the contents of soluble proteins, sugars, and proline showed an increasing trend.
Under the D2 treatment crossed with different salt concentrations, SOD, POD, and CAT activities showed a trend of initially increasing and then decreasing with increasing soil salt concentration compared to CK.
