BIOCHEMICAL STUDIES ON DEVELOPING AND RIPENING BANANA
M.A.A. Khan and M.
Anwarul
Haque Abstract: The contents of auxin, N and phosphates were determined at various stages of development of Sagar Kala variety of banana fruit. In the first 30 days auxin could not be detected in the fruit but N and inorganic phosphate contents decreased. Auxin was, however, found present in uniform quantities in bananas from 45 to 90 days old when the level of N and inorganic phosphate remained almost unchanged. In the third stage i.e. ripening stage from 90 to 105 days there was over 3-fold increase of both auxin and N. A reduction in the inorganic phosphate content took place during this period with a corresponding increase in the level of organic phosphate—an observation highly suggestive to the formation of energy rich organic phosphate compounds associated with the climacteric rise of respiration during ripening.
