Cuticular wax variation in eggplant and its effect on postharvest storage quality
The study evaluates eight eggplant genotypes showing that cuticular wax structure and content directly affect postharvest storage quality identifying wax traits as key indicators of preservation potential
Cuticular wax in fruits is closely linked to postharvest performance, although its specific role varies among cultivars and remains poorly understood in eggplant. This study evaluated eight different genotypes to assess how wax structure and chemical composition influence storage quality.
A total of 99 wax compounds and abundant crystalline structures were identified, with significant differences in wax profiles among the cultivars. Correlation analysis showed that both wax layer density and total wax content were strongly associated with improved postharvest storage tolerance.
The findings suggest that cuticular wax traits can serve as important indicators for predicting eggplant postharvest performance, providing a theoretical basis for selecting cultivars with better storage potential.
