The effect of auxine and cytokinine hormones concentration on photosynthetic pigments and proline amino acid under drought stress condition in maize hybrid 704
This study was conducted to determine some physiological parameters of maize cultivar KSC 704 affected auxin and cytokinin hormones concentration variations under drought stress condition. 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.
