The article presents the results of the study of the size characteristics of cenopopulations
Hypericum perforatum L.(Hypericaceae) and Saponaria officinalis L.(Caryophyllaceae),
which are formed in different phytocoenoses of North-East Ukraine. We have studied six
cenopopulations Hypericum perforatum from softwood, mixed and broadleaf forests and
seven cenopopulations of Saponaria offiсinalis from meadows with domination of Elytrigia
repens (L.) Nevski. During the research there were used a morphometric analysis, a …

The size of plant organisms, to a great extent due to the attached way of life, is their
extremely important basic characteristic. Many plant properties are closely related to the
size: life expectancy, place in the biogeocoenosis of the species, role in the food chain of the
ecosystem. Individuals of different sizes contribute unevenly to bioproducts, differ in the
nature of intra-ecosystem bonds, and have different degrees of resistance (Law, 1983;
Toshihiko, 1988; Marba et al., 2007; Zlobin, 2009). Of particular significance, morphometric …
