The fruit growth followed a sigmoid pattern and took about 9 months to attain maturity. The juice accumulation in the fruit started after 3 months from the setting. Total soluble solids and sugars showed gradual increase alongwith the advancement of maturity. Acidity and chlorophyll contents decreased, whereas Vitamin C and carotenoids increased with the development of the fruits. The carotenoid contents increased rapidly up to 1st January, after which these were levelled off.
