DEVELOPMENT OF METHODS FOR EXPRESS-EVALUATION OF RESOURCES OF HYPERICUM PERFORATUM L.

Abstract

The results of development of the model of resource evaluation of Hypericum perforatum L. in the field, based on statistical analysis of raw-material-relevant characteristics of populations of this species, including multivariate regression analysis, are presented. For a comprehensive statistical analysis of, the data of Hypericum perforatum populations, the projective cover, density of the stock of raw materials, plant height, height of raw part of the shoot, shoot density, mass inflorescences of one shoot, the diameter of complex inflorescences were selected from different regions of Ukraine. Among six analyzed parameters of H. perforatum, projective cover, shoot density and mass of the partial escape were the statistically significant. The most significance resource from characteristics of H. perforatum is the mass of the one raw shoot, which is closely correlated with the diameter of inflorescence and height of raw shoots. On the basis of statistical data, the table for express-evaluation of resources of St John’s wort was developed. That model of rapid resource evaluation provides data validity of resource significance in popu­lation and in future it can be improved.
