Abstract: Various chemical changes were studied during ripening of four sapota (Achras zapota [Manilkara zapota]) cultivars, viz. Cricket Ball, Ever Bearer, Bangalore Giant and Calcutta Round, at ambient temperature (25-30 degrees C) and relative humidity of 70-90%. Significant changes during storage were recorded in physico-chemical constituents of all the cultivars studied. The ripening process started first in Ever Bearer and its total soluble solid contents, total sugars, reducing sugars and ascorbic acid accumulation declined after 4 days. All the cultivars had a storage life of 6 days whereas Ever Bearer could only be stored for 2 days at ambient temperature.

Journal of Applied Horticulture, 2000, volume 2, issue 1, pages 28-30.

Abstract: Callus was induced from different explants of in vitro raised seedlings of C. aurantifolia to study the response of explants and medium composition on frequency of callusing and to develop reliable protocol for high frequency of plant regeneration from callus cultures. Shoot tip, epicotyl and hypocotyl were found superior explants for callusing in terms of amount of callusing, days to callus and callus induction frequency. Addition of cytokinin was found indispensable for regeneration and MS medium enriched with BAP [benzyladenine] (5 mg/l) resulted in highest per cent of callus regeneration. Regenerants were rooted in vitro and hardened in plastic pots containing autoclaved soil.
