As a part of the different phytocenoses, Plantago major L. undergoes significant anthropogenic effects and requires detailed study and development of measures for the preservation and reproduction of its populations. The issues of changing the morphometric parameters, depending on the forest site type and the stand density, remain poorly studied. The study of morphological parameters P. major allows to interfere purposefully in the processes of growth and development of plants, to use more fully the natural properties of plants, to preserve and reproduce the population and increase its productivity. In this article analyze the dimensional features P. major plants and to determine their morphometric features in different phytocenoses in Shostka geobotanical district of Sumy region.
To determine the dimensional parameters of plants of the researched species, we made a morphometric analysis. For this purpose, a number of static metric and static alometric parameters were evaluated in the studied cenopopulations. As a conclusion, we can say that, рlants of P. major show a rather diverse nature of changes in the magnitude of morphological parameters relative to the group in which they grow. Formation of plants P. major in the group Plantagetum (majoris) urticosum (dioici), is characterized by the smallest static metric and alometric parameters indicating the proximity of places to ecological-cenotic stress conditions. Conversely, the presence in the group Pinetum (sylvestris) sorboso (aucuparii)–urticosum (dioici) of large-sized individuals, which are also distinguished by the highest values of a number, static metric and alometric parameters, indicates the proximity of this location to the ecological-cenotic optimum and the relation of the population to the prosperous. Based on the obtained results, we can say that, the morphometric structure of P. major populations significantly changes during the transition from one phytocenosis to another. This feature indicates the ability of this species to adapt to different growth conditions.
On the basis of the obtained quantitative and qualitative characteristics of the cenopopulations of the researched species, we are able to distinguish more fo estimate the resource potential of P. major and to propose scientifically grounded approaches for the rational use of available stocks of valuable medicinal raw materials in the research area.
