Abstract

Triamidefon is a triazole derivative, which have both fungicidal and plant growth regulator (PGR) properties, and also protect plants from several types of abiotic stresses. The influential mechanism of Triamidefon on plants is not much studied. In this study effect of this compound on the drought stressed in tomato plants was investigated. The plants were subjected to 5 day interval drought stress and drought stress with TDM (15mgl-1) and TDM alone from 30 days after sowing. The plant samples were collected for estimating the related analysis. Individual and combined drought stress and TDM treatment increased dry weight, Chlorophyll content, SOD, CAT, PPO activities and decreased leaf area and prolin content. From the result of this investigation it can be concluded that the application of TDM caused a partial recovery of the damaging effect of drought stress by its influence on antioxidant system.
