Composite coating of chitosan with salicylic acid retards pear fruit softening under cold and supermarket storage.

Fruit softening is enzyme mediated degradation process determined by the action of cell wall modifying enzymes. Present study evaluated the combined effects of chitosan (CH) and salicylic acid (SA) coatings in modulation of fruit softening enzymes in Punjab Beauty pear (Pyrus pyrifolia × Pyrus communis) fruit stored under cold (0-1 °C and 90-95 % RH) and supermarket (20-22 °C and 80-85 % RH) conditions. Composite CH + SA coatings reduced mass loss and retained fruit firmness throughout the 67 and 20 days storage period.

Influence of pre-harvest sprays of calcium nitrate on storability and quality attributes of plum fruits.

The effects of pre-harvest applications of calcium nitrate at different concentrations were investigated on storability and quality attributes of plum fruits under low temperature storage. Uniform and healthy trees of plum Satluj Purple were sprayed with calcium nitrate (1.0%, 1.
