The results revealed a highly significant difference in genome size between cultivated and wild jujube (U = 22494.0, p < 0.001), with the median genome size of cultivated jujube (3.49 × 10 8 ) being significantly larger than that of wild jujube (3.37 × 10 8 ), and the Common Language Effect Size (CL = 0.355) confirming the practical relevance of this difference.
