Abstract: L. chinensis (cv. Rose Scented) fruits harvested from 16-year-old trees grown in Pantnagar, Uttar Pradesh, India, on 3 and 6 June [year not given] were subjected to various postharvest treatments (dipping of fruits in 200 ppm gibberellic acid or in 16.6, 20.0, and 25.0% wax emulsion for 2 minutes) and stored under ambient (21.8-29.0 degrees C and 41.0-98.0% relative humidity) or cold (5 degrees C and 85% relative humidity) storage conditions for 8 days. Physiological weight loss (PLW) and spoilage increased, whereas titratable acidity decreased with the increase in storage duration. Total soluble solid content increased up to 5 days of storage, then decreased thereafter. Fruits harvested on 3 and 6 June had lower PLW when treated with 25% wax emulsion (3.94 and 4.76%, respectively) and stored under cold conditions (4.32 and 4.43%, respectively). Fruits harvested on 3 June exhibited lower spoilage incidence when stored under ambient temperature (25.64%) than under cold conditions (26.33%). For fruits harvested
