Abstract

It is known since the 1990s that smoke from burning plant biomass can enhance seed germination or seedling growth for numerous plant species. However, our understanding of the eff ect of plant-derived smoke on the sprouting of asexual reproductive organs is insuffi cient. In a laboratory experiment, we tested the hypothesis if smoke treatment (applied as aqueous smoke solution, i.e. smokewater) enhances sprouting of the asexual reproductive organ for three herbaceous perennial plant species: Convallaria majalis L., Poa bulbosa L. and Ranunculus ficaria L. The smoke treated plant organ was rhizome (C. majalis), bulbous shout base (P. bulbosa) or tuberous root (R. ficaria). We recorded first shoot length, first leaf diameter and number of leaves for R. ficaria, shoot length for C. majalis, and rate and speed of sprouting for P. bulbosa. For none of the species and recorded variables had the smoke treatment signifi cant diff erence compared to control (moistened with tap water). However, the smoke treated P. bulbosa's survival was signifi cantly higher, and a higher number of C. majalis individuals compared to control remained alive until the end of the experiment. Th us, our results do not support the hypothesis on the positive eff ect of plant-derived smoke on the sprouting of asexual reproductive organs. However, the benefi cial smoke effect on the survival was shown. This latter result opens an opportunity to use smoke technology in a new as pect: in ex situ conservation programs using propagation from asexual reproductive organs, greater efficiency can be achieved with smoke treatment. Nevertheless, these results are far insufficient to draw a general conclusion on the issue. Further studies are needed involving a much larger number of plant species and various smoke treatments (e.g. aerosol smoke or diff erent dilutions of smoke-water).
