Potencjał allelopatyczny wyciągów wodnych z chwastów w stosunku do siewek pszenicy ozimej i żyta
Streszczenie
The purpose of this research was to determine the influence of water extracts derived
from weeds: wild horsetail (Equisetum arvense L.), nettle (Urticae dioica L.) and their mixtures
on different levels of concentration (0; 1; 2; 3%), by soaking and watering the grain on the
germination ability and the initial growth of the winter wheat (Triticum aestivum L.) and rye
(Secale cereale L.). Results showed that, water extracts from the wild horsetail had a greater
impact on the checked parameters of both the winter wheat and rye, than the extracts derived
from nettle and their mixtures. Used water solutions from weeds compared with the distilled
water hindered the initial growth of plants; reduced the germination ability, length and mass of
seedlings, in addition the solutions with the most inhibitory interaction were the ones with the
highest concentration (3%). Solutions, with lower concentration of 1 and 2% had similar
interactions with the range of checked parameters, especially a length of seedlings and their
mass. However the way of application of water solutions had a greater impact on the
parameters of winter wheat rather than rye’s. Soaking the wheat in comparison with watering
caused the reduction of the grains germination capacity, but increased length and mass of
seedlings. In case of rye soaking increased the mass of seedlings.
