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 deg C and 41.0-98.0% relative humidity) or cold (5
deg 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 on 6 June, cold storage resulted in lower spoilage
incidence (39.86%) than ambient temperature storage (51.12%).
Gibberellic acid treatment gave the lowest spoilage incidence (15.75 and
32.47%, respectively) and highest total soluble solid content (20.74
and 20.55 deg Brix, respectively) in fruits harvested on 3 and 6 June.
