Abstract

Guava fruits of the variety Safeda (Allahabad) were examined at 10-day intervals during initial growth and at 5-day intervals during ripening in 1964-66 for physical and chemical changes during development. The period from fruit set to full ripe stage was covered. The growth curve as shown by fruit weight was of sigmoid type. Fruit length-width ratio, specific gravity, colour and firmness showed marked changes during development. Soluble solids, sugars, titratable acidity, ascorbic acid and total pectins showed peaks just before fruit drop. All chemical constituents showed consistent patterns of change during fruit development suggesting several discrete physiological stages; viz., prematuration, maturation, ripening and senescence.
