Demonstrates enhanced fruit quality in mango through GA3 treatment, suggesting effective resource allocation.

The aim is to assess how exogenous gibberellic acid affects mango fruit quality by regulating metabolic pathways.
Conducted a controlled application of GA3 at various concentrations (0, 50, 100, 200 mg L−1)
Measured fruit physiochemical attributes during expansion and ripening phases
Analyzed metabolic profiling and pathway analysis post-ripening
Performed PCA to identify optimal treatment
GA3 at 50, 100, and 200 mg L−1 increased fruit length by 8%, 12%, and 14%, respectively
Single-fruit weight increased by 5–11% at physiological maturity
GA3 treatment reduced starch and total acidity by up to 11% and 29%
Fruits exhibited lower weight loss and higher firmness with reduced disease incidence
287 differentially regulated metabolites were identified between GA100 and the control

Zhai et al. (2026) studied this question.
