This study was conducted to determine the possible role of growth regulators and the effect of foliar part cutting on the tuber formation of C. serotinus. Foliar application of 6-benzylaminopurine (BA) increased tuber number and fresh weight of C. serotinus by an average of 24.7 % and 32 %, respectively, as compared with the untreated control. However, the tuberization of C. serotinus was inhibited by single treatment of abscisic acid (ABA) and gibberellic acid (GA) as the concentrations increased. As compared with the untreated control, BA at 10-4M and combination of BA 10-5 + GA 10-5M increased 31.8 % and 53.7 % of tuber number, respectively, but GA at 10-5M decreased tuber number by 21.9 percent.
