THE ALLELOPATHIC EFFECT OF HORSERADISH (ARMORACIA RUSTICANA L.) WATER EXTRACT, ON PEA (PISUM SATIVUS L.) AND CUCUMBER (CUCUMIS SATIVUS L.), GERMINATION AND PLANTELS GROWTH. In this study, we purpose to evaluate the phytotoxic effect of allelopathic substances from horseradish (Armoracia rusticana L.) on pea (Pisum sativus L.) and cucumber (Cucumis sativus L.) seeds germinated, made on filter paper substrate, moisted with horseradish water extract, used in different concentrations (5, 15, 25, 50, 75 and 100%); after 7 days of germination, we determined the length of the roots and shoots. The results which were obtained denoted a significant negative influence exercited by this extracts on seeds germination, and on plantlets growth, especially, of the solutions which were prepared from the roots harvested in the flowering period of the plant.
