Abstract
This study was carried out in 2006 & 2007 seasons, using three cultivars i.e., Flordaprince, Desert Red and Meet Ghamr to determine fruit maturity and study the effect of cold storage on fruit quality and marketability. Fruit weight, skin and flesh colour (a) values were gradually increased during maturation. In Meet Ghamr skin (b) values were increased till the age of 121 days, then decreased at the age of 128 days and displayed the lowest (a/b) values. Flesh colour of Desert Red was much more yellow than that of Flordaprince, while Meet Ghamr displayed red colour. Reductions in firmness and total acidity were showed with advanced stage of fruit maturity, while SSC and total sugars showed inversely trend. Weight loss, SSC, SSC/acid ratio and total sugars increased during cold storage and this increment was continuously observed during subsequent 4 days at 20oC. Firmness, acidity and phenols behaved inverse trend and this trend remained during cold storage and marketing period. Symptoms of decay were visible in fruit of all cultivars between 15 and 20 days of cold storage.
