Abstract

In order to evalution of antioxidant enzymes activity and yield of flower of chamomile genotypes under drought stress condition and foliar application of nano iron chelated, a factorial experiment in a randomized complete block design with three replications was conducted at greenhouse research farm of the University of Zabol in 2014. Experimental treatments included drought stress at 2 levels (control or 90% of field capacity and 70% field capacity) and nano iron chelate application at 2 levels (control and 2 mg/l) and chamomile genotypes (Ardestan, Gachsaran, Nain, Khozestan, Kazeroon, Germany and Hungary). In this study the antioxidant enzymes activity (catalase, peroxidase, ascorbate peroxidase, guaiacol peroxidase, polyphenol oxidase and total protein) and the yeild of flower in plant of information about the resistance to drought stress were evaluated. The results showed that stress caused an increase in the catalase decrease cause of enzyme activity in genotypes in Kazerun, Khuzestan, Nain and Germany, the enzyme ascorbate in every genotypes, guaiacol peroxidase in genotypes, Kazeroon, Khuzestan, Nain and Germany and decreased total protein genotypes in genotypes of ardestan, Gachsaran and Hungary and the yeild flower in plant of in the genotypes in Ardestān, Khuzestan, Nain and Hungary. Application of nano iron chelated by reducing the damaging effects of stress on the antioxidant enzymes in some of genotypes was influenced that, this effects some of genotypes was positive and negative in others genotypes. In generally, the use of genotypes in Khuzestan and Germany are sufferest for planting in the drought stress conditions.
