Abstract
In this study, the effect of burning plant debris on germination and growth of 7 different weed species was investigated. In general, burning plant residues reduced germination and growth rate of 7 studied weed species, but its effect on some was less than other studied species. The chemical effect of smoke depends on the type of weed, so that the chemical effect of smoke reduced the germination of portulaca oleracea and sorrel and increased the germination of wild oats compared to the control, but had no effect on the germination of barley, wild roe deer and leeks. In general, no significant difference was observed between soot and control treatments for germination percentage and germination rate, but fire and fire + soot treatments were significantly different from the control. Therefore, the reason for the reduced germination and germination rate of weeds after burning plant debris is the physical cause (heat) of the fire, not the chemical.
