The paper reports an experiment designed to give information on the fate of sucrose in the ripening berry.

Individual excised sultana berries were presented with radioactive sucrose, glucose or fructose and the distribution of radioactivity in sugars and organic acids was examined.

The results suggest that glucose and fructose accumulate in pool seperate from the sites where sugar interconversion and breakdown take place and that the sugar utilised in metabolic processes is probably derived primarily from sugar transported into the berry.
