EFFECT OF THE AQUEOUS EXTRACTS OF AMORACIA RUSTICANA L. ON THE SEED GERMINATION AND SEEDLING GROWTH OF ZEA MAYS L. UNDER DROUGHT STRESS
AbstractHorseradish (Armoracia rusticana L.) is a perennial plant cultivated all over Europe, having an allelophatic effect on the germination and seedling growth at many species of plants. The experiment described in this paper examines a series of concentrations of aqueous extracts of horseradish roots in conditions of drought stress induced by NaCl, at maize. The effects of the extracts were significant on final germination rate (Gr), shoot length (SL) and root length (RL). The extracts having concentrations of 10% and 15% had a significant stimulating effect on the studied traits, and the increase of the concentration of the aqueous extracts to 20% caused the inhibition of these traits. Therefore, the aqueous extracts of horseradish could help germination and seedling growth of maize reducing the negative effect of drought stress.
