Physiological differences of chlorophyll (a), MDA (malonaldehyde) (b), proline (c), soluble sugar (d), soluble protein (e), SOD (superoxide dismutase) (f), POD (peroxidase) (g), and CAT (catalase) (h) in diploid and autotetraploid sour jujube plants under control and drought conditions. The dot represents the value of biological repetition. The vertical bars show the standard error. For the difference between diploid and autotetraploid, “*” represents significance level of 0.05 and “**” represents significance level of 0.01
