Influence of aqueous extracts of aboveground organs of common crop weeds ‘Stellaria media’ on germination and seedlings growth of radish (Raphanus sativus L. var. radicula Pers.) was studied. Three different cultivars of radish (i.e. ‘Rowa’, ‘Krakowianka’, and ‘Półdługa’) were used to investigate if Stellaria media could produce allelopathins and if the impact of allelopathins differs between cultivars. The influence of allelopathins in various form of extracts was checked, i.e. decoction, infusion, and macerate, as the impact on germination rate, seedling growth (length and mass), and electrolyte leakage. Compared to the control group (application of distilled water), the germination rate of radish seeds was lower irrespective of the type of S. media extracts used. The growth of seedlings differed between cultivars and form of extract. The inhibition of seedling growth for ‘Półdługa’ cultivar was noticed irrespective of extract type. The growth parameters of two other cultivars was stimulated by the infusion, and slightly inhibited by the decoction and macerate. The extracts reduced the outflow of electrolytes through the cell membranes of all but one radish seedling in which the macerate treatment increased the electrolyte leakage in the ‘Rowa’ cultivar.
