Morpho-anatomical structure of the leaf apparatus of spring barley under the influence of herbicide and plant growth regulators

It has been found that the number of epidermal cells of spring barley leaf apparatus on the surface unit of the leaf decreases while their size increases under the application of herbicide Calibre 75 at the rates of 30, 40, 50, 60 and 70 g/ha in mixtures with Agat - 25K which is consistent with the formation of anatomic structure of the leaf apparatus belonging to mesomorphic type.
