Abstract

'Dwarf Cavendish' bananas exhibited a concave growth curve and took 130 days to reach full maturity after inflorescence emergence. Pulp to skin ratio increased from an initial value of 0.25:1.0 to 1.9:1.0 at full maturity. Fruit wt. increase was max. during the final 4 wk of growth. DM and starch content in the pulp increased consistently up to 100 days of growth, after which there was negligible change in starch, whereas DM content decreased. Skin tissues showed less marked changes in DM starch. Soluble sugars in pulp and skin remained at low level during growth. Titratable acids, ascorbic acid and N in the pulp tended to increase from 43 days onwards, while in the skin no perceptible changes were noticed throughout the growth period. Total phenols, flavonols and leucoanthocyanidin content showed a continuous fall as the fruit matured. Fruit respiration was max. at the early stages of development, fell rapidly thereafter and remained steady during the later stages of maturation. Results indicate that the biochemical status of bananas does not change appreciably during the final stages of maturation and, therefore, a combination of chronological age and pulp to skin ratio could be used as in index of maturity at harvest.
