Abstract
A significant increase in the number of tubers was obtained in the pre sence of either kinetin (11.6.10(-3) mM), paclobutrazol (8.5.10(-3) mM ) or acetate (5.4 mM) for in vitro stolons in darkness, and both singl e-node sections and intact 3-cm long sprouts were produced after long photoperiod (16 h) subculture. Longitudinal growth decreased whenever tuberization was promoted, especially in the presence of paclobutrazol . Calcium chloride (6 mM) slightly induced tuberization in the dark. P utrescine (0.15 mM) favoured vegetative development in all explants.
