Title
ALLELOPATHIC EFFECTS OF STELLARIA MEDIA ON
GERMINATION AND EARLY STAGES OF GROWTH OF RAPHANUS
SATIVUS var. RADICULA
Authors
Abstract
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.
