Fruit physico-chemical and quality parameters of mango cultivars as influenced by seasons

A study on physiochemical and quality characters of different mango (Mangifera indica L.) cvs. grown under Kanyakumari and Tenkasi conditions was carried out at Horticultural College and Research Institute Periyakulam in the year 2010-2012. tencultivars were studied for pysico-chemical and quality aspects. Among the ten cultivars each cultivars randomly collected ten fruit and analyzedphysico-chemical and quality characters from main as well as off-season at Kanyakumari and Tenkasi location of both main as well as off-season. In the present study also, physico-chemical parameters viz., fruit weight, fruit girth, pulp weight and stone weight. The highest fruit weight was recorded in cv. Bangalora (14.75 and 14.00) followed by cv. Banganapalli (13.20 and 12.50), in case of fruit girth was observed in cv. Bangalora (13.22 and 12.35) followed by cv. Banganapalli (12.60 and 12.15) whereas pulp weight was recorded in cv. Bangalora (235.50 and 213.45) followed by cv. Banganapalli (198.60 and 186.60) and stone weight was recorded in cv.Bangalora (97.10 and 86.12) followed by cv. Banganapalli (87.25 and 83.82) both main as well as off-season. quality improvement of fruits with respect to total soluble solids, reducing sugars, non - reducing sugars, total sugars, total carotenoid content, ascorbic acid content and lower acidity response to location, season and varieties. The highest total soluble solids (20.300Brix), reducing sugar (7.50%), non-reducing sugar (13.50%) total sugar (21.00%), carotenoids (7.70 mg 100 g-1), ascorbic acid content (29.50 mg 100 g-1) and lowest acidity content (0.20%) was registered by cv. Kale pad during Main season, whereas the highest carotenoid content was observed by cv. Neelum during Main season. The highest ascorbic acid content was recorded in cv. Alphonso during main season.
