Regression of citrus genotype due to storage time (days) across six varieties of citrus: citrus (A), grapefruit (B), hybrid (C), lime (D), mandarin (E), and orange (F). The regression values (indicating a strong correlation if R² > 0.7 [128]) and significance (considered significant if P ≤ 0.05) of vitamin C across various types of citrus fruits in relation to storage duration (days) are assessed.
