Reseda is an understudied genus regarding germination ecology. We studied the response of eight perennial species to fire related cues by performing a experiment including two aqueous smoke treatments (at 1:5 and 1:20 concentrations), one heat shock (100 °C for 5 min.) treatment, corresponding controls. Smoke slightly decreased percentage in R. aucheri ssp. rotundifolia minoica, reduction luteo...
