Regression modelling of postharvest quality parameters of bitter gourd (Momordica charantia L.) under different packaging methods

Bitter gourd (Momordica charantia L.), a highly perishable Cucurbitaceae vegetable, undergoes rapid quality deterioration after harvest. The current study evaluated the effects of packaging methods such as low-density polyethylene (T1), cling film (T2), shrink wrap (T3), and no packaging (T4), under ambient (S1) and cold storage (S2) conditions using a factorial completely randomised design. Observations on physiological loss in weight (PLW), firmness, colour, spoilage, and shelf life were recorded over ten days. ANOVA revealed significant effects (p
