The respiratory drift of intact fruits followed a similar course as that of fruit slices. The climacteric
rise occurred about 40 days after anthesis. The relative importance of pentose phosphate (PP)
pathway and of glycolytic (EMP) pathway of glucose dissimilation was estimated by fluoride
inhibition and by assaying of glucose-6-phosphate dehydrogenase activity. It was found that during
the later stages of fruit development the contribution of the EMP pathway was increased while that
of the PP pathway was decreased, the reverse was true at the early stages of fruit development. The
favourable effects of pyruvate, malate, citrate and succinate and the inhibitory effect of malonate on
melon fruit respiration suggested that the tricarboxylic acid cycle was operating in the fruit tissue.
The results also indicated that the activity of the TCA cycle was higher at later stages than at early
stages of fruit development. As the fruit reached the mature stage an increase in fermentation
capacity was also noted.
