In order to investigation effect of hexaconazole in some morpho- physiological traits of Althaea officinalis in drought stress, the experiment was conducted factorial in the base of complete randomized design with four replications in greenhouse of Islamic Azad university of Neyshabur branch in 2012- 2013. Treatments were drought (50%) and control (100%) field capacity and sparying of hexaconazole solution in two concentrations (15 and 25 mg/L) and control. Sampling was done about 125 days after growing, before reproductive growth stage. In the base of comparison of means, drought stress the reduction of other traits except root length, content of proline, protein and catalase activity. The interaction between drought and hexaconazole were significant on the number and leaf area, stem length, stem to root ratio, fresh and dry weight, proline content and activity of peroxidase enzyme. Also, 15 mg/L concentration of hexaconazole compared to other levels, increasing the contents of root length, soluble carbohydrates and protein. Also, number of leaf, stem length, proline and peroxidase enzyme content had decreasing in lower level than higher level of hexaconazole. In the base of the results, high concentrations of triazole compounds can be made further increase growth on Marshmallow in drought conditions as a substance that can be used to reduce the effects of stress.
