Abstract

A study undertaken to assess the effects of harvest dates, calcium chloride and storage of pear fruit cv. Bartlett revealed that fruits harvested 110 and 115 days after full bloom (DAFB) showed rapid colour development, decrease in firmness, less physiological loss in weight, higher organoleptic rating and more spoilage. However, late harvested fruits recorded less acid content, higher TSS, total and reducing sugars, decreased in starch content and more calcium content. The fruits treated with calcium chloride showed delayed colouration, improved, fruit firmness, organoleptic rating, TSS, sugars , both peel and flesh calcium content and reduced physiological loss in weight, spoilage and acidity. After 15 days of storage period, fruit colour, physiological loss, spoilage, organoleptic rating increased and fruit firmness decreased. Comparatively, TSS, sugars, starch content, calcium content (both peel and flesh) increased and the acid content decreased. Fruits harvested 110 and 115 DAFB and treated with calcium chloride at 0.5 and 0.75% retained all the Physico-chemical characteristics and enhanced the storage and keeping quality.

Keywords: Calcium chloride, harvest date, pear, Physico-chemical characteristics and pre-harvest treatment.
