ALLELOPATIC INFLUENCE OF WEEDS ON THE GERMINATION OF WINTER WHEAT SEEDS
Okrushko Svetlana Evgenivna – Candidate of Agricultural Sciences, Senior Lecturer of the Department of Botany, Genetics and Plant Protection of Vinnitsia National Agrarian University (21008, Vinnitsia, Soniachna Str. 3, e-mail: osy@vsau.vin.ua).
The article summarizes the results of the phytotoxic effect of water-soluble extracts from various weeds on the germination processes of winter wheat seeds. Competitive relations between plant organisms begin with chemical interaction. Therefore, the competitive properties of the participants of the cenosis and the level of productivity of its components will depend on the starting conditions that are formed during the germination of the seeds of the crop. The research was carried out in the laboratory of plant physiology of VNAU. The purpose of the research was to establish in laboratory conditions the allelopathic effect of water extracts from the most common weeds of the Vinnytsia region: Convolvulus arvensis L., Sonchus arvensis L., Cirsium arvense L., Erigeron canadensis L., Matricaria perforata Merat, Capsella bursa pastoris, Erodium cicutarium L., Chenopodium album L., Galium aparine L., Stellaria media L. Water extracts from the stems, leaves and root system of weeds were prepared at a concentration of 1:10. During the experiment, it was established that the presence of allelopathically active substances of all experimental weed species of this concentration negatively affects the germination energy of winter wheat seeds. In the control version, all the seeds of the culture germinated on the 4th day, and in the experimental versions, 1-3% of the wheat seeds were in the swelling phase. Water extractions of different types of weeds had different inhibitory effects on winter wheat seed germination and subsequent growth of the root system and sprout stems. The negative effect of water-soluble secretions from Erodium cicutarium L., Cirsium arvense L. and Sonchus arvensis L. reduced the height of wheat seedlings by 5.8-4.0%. And the length of the root system of the culture was smaller by 5.7, respectively; 5.8 and 5% compared to the control variant. Water-soluble extracts from Stellaria media L. and Matricaria perforata Merat. had the least influence on the growth processes of winter wheat. The difference in sprout height from the control variant was 1.3% and 2.0%, respectively. The length of the germinal root of wheat was shorter by 1.8% and 3.8% under the influence of water-soluble secretions of asteraceae and chamomile. The total length of the root system of winter wheat was inhibited by them by 2.4% and 2.6%, respectively, in relation to the control. The results of the conducted research provide justification for the appearance of unfriendly seedlings and the lag in the growth of winter wheat plants on weedy areas.
