Fire is a major factor that affects plants and their development. Different plant life stages like germination, seedling establishment, flowering and seed dispersal can be influenced by fire or one of its derivatives. Fire smoke and its components were described as an important environmental factor to enhance seed germination and to improve seedling vigor in a number of studies. In this study, using different concentrations of 0, 25, 50, 100, 250, 500 and 1000 ppm of synthesized butenolide showed that response of the medicinal plant L. sativum L. seed germination and seedling development is concentration depending. The effect was varying among the concentrations but in general, low concentrations reflect positive effect and, on the other hand, high concentrations caused inhibition due to phytotoxicity of butenolide to the receptor plant cell. While, physiological and clastogenic abnormalities were found.
