Effects of smoke and heat-shock on germination in eight perennial Reseda species (Resedaceae)

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 luteola was statistically significant (P < 0.01). In contrary, promoted coodei, globulosa, orientalis slightly, markedly anatolica (from 3 11%; P = 0.055). Heat treatment did not affect three four tested, but significantly increased comparison control 0.046). Consequently, there no consistent or studied. This study most comprehensive tested fire-related several provides first results on seven species. Further studies that include more would show completed figure patterns Reseda.
