Abstract EN
Baltic seaweeds were used to obtain aqueous extracts (E) through changing initial pH of deionised water added to algal biomass (EpH3·H2O, EpH7·H2O, and EpH10·H2O) and through changing pH of the mixture of algae and deionised water (EpH3, EpH7, and EpH10).
Algal extracts were characterized in terms of the concentration of polyphenols and micro- and macroelements.
The highest concentration of polyphenols was determined in extract EpH3 and the lowest in extract EpH10·H2O.
It was found that the obtained extracts had similar concentrations of elements (except EpH3).
The phytotoxicity of algal extracts (0.5, 2.5, and 10%) was examined in the germination tests on Lepidium sativum.
No phytotoxic effects were observed.
It was found that they had beneficial effects on the cultivated plants (length and weight).
The best biostimulant effect was observed in the groups treated with EpH3 (2.5%), EpH7 (2.5%), and EpH7 (10%).
The dry weight of plants was similar in all the groups.
Algal extract also improved the multielemental composition of plant.
The greatest concentration of total chlorophyll in plants was obtained by using extract EpH10·H2O, 0.5%.
These results proved that algal extracts have high potential to be applied in cultivation of plants.
