This research had been conducted to investigate the response of two wheat cultivars to cytokinin and

droughtness treatments through plant height, number of tillers per plant, flag leaf length, number of

kernel per spike, weight of 100 kernels, protein, and total carbohydrates content of kernels. The maximum

mean value for plant height was recorded for Sham-3 cultivar at 80 ppm which is significantly increased

as compare to control, while the flag leaf length increased nonsignificantly at 40 ppm. Treatments with

40 and 80 ppm significantly decrease weight of 100 kernels for Mexipak cultivar, while in Sham-3

cytokinin at all concentrations significantly decreased weight of 100 kernels. It is obvious that cytokinin

treatments with drought plants was less affective compared with normal irrigation with regard to

carbohydrate content for Mexipak cultivars. In Sham-3, the results showed that the carbohydrate

percentage in all cytokinin treated plants whether, drought or irrigated, were decreased significantly,

while the weight of 100 kernels has not been changed in CK3D compare to the CK0N but increased

significantly when compared with CK0D.
