Post-harvest studies on some local geno-types of ber (Zizyphus mauritiana Lamk) grown in West Bengal

The length, diameter and weight of fruit as well as pulp and seed weight of ten local ber geno-types grown in West Bengal were compared. The average weight of fruit varied from 8 to 17.68 g. The chemical constituents such as total soluble solids, total sugars, reducing sugar, non-reducing sugar, acidity and ascorbic acid contents also exhibited significant differences. The ranges of variation in total soluble solids, total sugars, reducing sugar, non-reducing sugar, acidity and ascorbic acid contents of different ber types of were 9.53–19.13 per cent, 4.94–12.30 per cent, 2.14–4.99 per cent, 2.37–8.50 per cent, 0.38–2.60 per cent and 17.25–51.98 mg/100 g, respectively. The fruits in majority of geno-types could be stored upto 6^th day with a considerable acceptable quality.
