This study was carried out in order to determine and compare changes in physicochemical properties
of bulbils from two cultivars (yellow and mauve) of Dioscorea bulbifera at different periods during the growth.
The tests were performed on the bulbils from one to six months of age. The results showed that the weight of
bulbils of both cultivars increased. They were ranged on fresh weight basis, from 31.88±13.1 g to 314.93±16.87
g for yellow cultivar and from 10.26±5.17 to 61±14.17 g for mauve cultivar. Starch content, like lipids, total
and reducing sugars, cellulose and ash increased also. Starch was the most abundant chemical component with
values ranged from 62.09±5.45 to 78.5±5.2% and from 60.56±3.05 to 70.57±6.87%, (on dry weight basis) for
yellow and mauve cultivar respectively. Potassium is the most abundant mineral. It value increased during the
growth time and ranged (in mg per 100 g dry weight) from 109.2±0.30 to 451.9±0.41 and from 89.66±0,5 to
403.45±0.6 for yellow and mauve cultivar respectively. Bulbils physiological maturity might be set at sixth
month during the growth time as some components like Zn, Mg and protein reached a critical level after six
months.
