In the tannia , as in other tropical root crops which are vegetatively propagaged, improvement of the crop has depended mainly on the natural genetic variability among a small number of cultivars (Warid, 1970) and has, therefore, been severely limited. Any factor which leads to increased flowering, fruit set, seed germination and ultimately hybridization could therefore be of great significance in the improvement of these crops (Sadik and Okereke, 1975a,b). For this reason it was decided to report the promoting effect of gibberellic acid (GA) on the flowering in tannia which was observed in an experiment set up to test the effects of growth substances on corm and cormel development
