Effect of different ethylene concentrations on ripening behaviour of banana (CV. GRAND NAINE)

The present investigation was undertaken to examine the influence of ethylene gas on the ripening behaviour of banana fruits. The study was carried out in the postharvest laboratory of the College of Horticulture, Rajendranagar, using a Factorial Completely Randomized Design comprising two factors with four levels each and three replications. Banana fruits harvested at 85 per cent maturity were treated with varying ethylene concentrations (50, 75, 100, and 125 ppm) combined with different pulsing frequencies in a low-cost ripening chamber. A consistent reduction in Differential Absorbance (DA) meter readings was observed with the progression of ripening.
