The impact of plant-derived smoke on seed germination in the context of swailing

Renata Bączek-Kwinta , Marcin Markowicz


Smoke generated by wildfires have special ecological impact in various fire-prone environment in Africa, Australia, and both Americas. However, in the countries of moderate climate zones, swailing (controlled burning of meadows) is often, although illegally, practiced by farmers. Hence, the influence of smoke generated from plant debris on seed germination and radicle growth of 4 crops, popularly grown and 3 weed species, occurring in Central Europe was studied. Smoke had stimulative effect on seeds germination of 6 from 7 studied species. There was no impact on germination of meadow cress seeds, but in this case strong stimulation of radicle growth was noticed. The influence of smoke on germination was the strongest in case of red cabbage, as the difference between smoke-treated and control seeds was 60%, and the stimulation of growth of radicles was obtained. Summing up, plant-derived smoke can stimulate seed germination and seedling vigour of some crop and weed plants of moderate climate countries. Therefore, smoke generated by swailing can cause local changes in both the natural and agricultural environments.
