The present study was conducted to determine the effect of plant-derived smoke extract on some under-ground and above-ground traits of two winter cultivars of wheat (Pishgam and Navid) as a factorial experiment based on a randomized complete block design (RCBD) with three replications. In this research, the effect of three concentrations of smoke extract (0, 1:10 and 1:100) on some growth traits of wheat including, number of tillage, shoot length, spike length, awn lenght, flag length, spiklet number per spike, leaf area, shoot fresh weight, shoot dry weight, root number, root length, root fresh weight, root dry weight, root dry weight/ root fresh weight, shoot dry weight/ shoot fresh weight, root/shoot fresh weight, root/shoot dry weight was studied. The results showed significant differences among various concentrations of smoke extract for the majority of traits. Concentration of 1: 100 was the best treatment compared to control. Futhermore, there was a significant diference between the two wheat cultivars, and the Pishgam cultivar was more than Navid in terms of majority of traits. The interaction of cultivar with smoke water concentration was significant for shoot length, shoot dry weight, shoot dry weight/ shoot fresh weigth, root fresh weight/shoot fresh weight, and in this case, the slicing method was used for data analysis. Finally, the consentration of 1:100 was the best smoke solution for all traits and the Pishgam cultivar showed a better response to smoke water.
