The experiment was carried out in three environments separately including non-drought stress environment, drought stress in vegetative stage and drought stress in reproductive stage. Cytokinin hormone in three concentrations (control, 50 and 100 mg/lit) in V8-V10 stage and auxin hormone in three concentrations (control, 10 and 20 mg/lit) in silk emergence stage was laid out as a factorial design based on randomized complete block with three replications in each environment at Seed and Plant Improvement Institute, Karaj in 2014. Drought stress in reproductive stage decreased chlorophyll a and b respectively %28.13 and %37.93. The use of cytokinine hormone in concentration 50 mg/lit increased %37.73 chlorophyll a and decreased % 16.58 proline amino acid and also auxine hormone in concentration 10 and 20 mg/lit increased %22.78 chlorophyll a and decreased %18.02 proline.
