ZAHOOR AHMAD SAJID AND FAHEEM AFTAB*
Abstract
Thidiazuron (1-phenyl-3- (1,2,3- Thiadiazol-5-yl) urea; TDZ) is one of the several substituted ureas that have been investigated recently for their cytokinin-like activity. TDZ is known to be more active than zeatin for stimulating the growth when added to a tissue culture medium at a low concentration. In this study, effect of TDZ on several In vitro growth parameters in Solanum tuberosum cvs. Desiree and Cardinal were observed. Shoot apices (1.0cm each) from both the cultivars were separately inoculated on full strength MS basal media as well as on MS full strength supplemented with different concentrations of TDZ (10-10
