The study of natural essential oils as growth regulators of winter wheat

Abstract

Growth regulators are rather important for obtaining high yields of agricultural crops. Recently, more and more research on biologically active substances has been carried out among natural products, in particular, essential oils of plants. Our study is aimed at the search for winter wheat growth regulators among essential oils. In three-year field small-plot experiments, the growth-regulating activity of anise, fenchel and apricot oils was studied. When we treated the vegetating plants with the water emulsions of the above mentioned oils (dose – 30 g/ha) twice in the tillering and the flag leaf phases, the yield increase of Grom winter wheat variety was 8.6–10.8 %. The quality of seeds also improved: the protein content increased by 0.6-1.1 %, gluten by 1.8-2.7 %.
