Salinity stress is of importan t limiting factor among abiotic stresses in ca tion production.This investigation was
conducted to evaluate the effect of triadimenol fungicide itriazole drivative) on reduction of deleteriou s effects of
salinity on seed germin ation, early growth stage of cotton. In laboratory, the 13 genotypes of cotton tGossyp ium
hirsutumy, NaCL solutions (5-20 ds/m) and triadimenol (7.5 D.S) concentrations 0.5-4:1000 (w/v) were used and
experiments were done by seed soaking and rolling towel methods. The results showed that, there were significant
differen ces (a=l%) among test genotype s in response to salinity stress. The genotype s Sea-land , Sindos-80, 43228,
Shirpan 539 and Siokra-324 had the most tolerant. The increase of triadimenol dose to 1:1000 (w/v) resulted in increase
of percentage and rate of germination, radicle length, stem length and weight of seedlings by 12.5, 2.9. 20.9, 53 and
7.4%, respectively. In field. The triadime nol seed treatment 1:1000 (gr./kg .seed) increased % emergen ce and seedling
weight(mg) by 1.3 and 14.8%, respectively in comparison with check.
