Abstract

This study aimed to examine whether the association between PT and VC content is influenced by the levels of TSS and AT content. More Specifically, the experimental analytical investigation involved 24 lemon Accession (Citrus limon (L.) Burm.), with a focus on the VC content in the fruits. Serial mediation analyses were conducted using Model 6 of Hayes’ PROCESS macro (version 4.2), with controls for weight, FL, number of seeds per fruits, and percentage of juice. The mediation analysis indicated that PT had a total effect of 31.74 (95% CI, 9.04-54.45) on VC content. This effect was divided into a direct effect of 7.13(95% CI, -14.15-28.40) and an indirect effect of 24.61 (95% CI, 12.16-37.93), with an estimated proportion of 77.54% being mediated by levels of TSS and AT. Additionally, TSS and AT were identified as independent factors contributing to the increase in VC content, serving as significant mediators in the relationship between PT and VC content. In summary, our findings suggest that levels of TSS and AT play crucial roles as mediators in linking PT to VC content. These findings have practical implications for optimizing vitamin C levels in citrus fruits.
