Effect of preharvest foliar application of calcium on the postharvest behaviour of sapota (cv. Kalipatti) fruits.

The effect of calcium chloride and calcium nitrate (both at 0, 0.25, 0.5, and 1.0%), applied at the fruiting stage, on the postharvest quality of sapota [Pouteria sapota] cv. Kalipatti fruits was investigated in Karnataka, India [date not given]. Fruits of uniform maturity were harvested 3 weeks after treatment and stored for 2 weeks. After storage, fruits from trees treated with 1.0% calcium chloride showed significantly higher total sugar content compared with the control and other treated fruits. Application of 0.25 and 0.50% calcium chloride or calcium nitrate increased the storage life by 2-3 days and significantly reduced postharvest fruit rotting, while 1.0% calcium chloride or calcium nitrate increased the percentage of postharvest rotting and did not significantly affect the storage life. The effects of the treatments on the sensory quality (general appearance, pulp colour, taste, aroma, firmness, and texture) of sapote fruits was also compared.
