Assessment of initial stock of Levisticum officinalіs C. Koch and Leonurus guinguelobatus Gilib on complex of attributes

Abstract

The purpose. To study influence of climatic conditions on growth, development and formation of productivity of Levisticum officinalis C. Koch and Leonurus guinguelobatus Gilib, as well as to determine adaptable potential of samples of initial stock. Methods. General scientific and special: field — for determination of differences in alternatives of research; laboratory — for determination of biochemical compound of raw material; gene­tic — for determination of parameters of combining ability; mathematical-statistical — for assessment of reliability of the gained results. Results. As to economic-valuable attributes of MLL and Koral they selected samples of lovage. Grades of foreign selection Lovage and Redei have appeared resistant against conditions of growing in low zone of Zakarpattia. Samples of motherwort are revealed which can be sources of the following valuable attributes: short term of vegetation (Krasunia, CRBS), height of a bush (SK-2, Zabava, CRSB), diameter of a bush (Krasunia, Zabava, SK-1), content of useful matters (Zabava, SK-2, Krasunia), amount of caulises (SK-1, SK-2), branches of the 1st and 2nd orders (Zabava, SK-2) and racemes (SK-1, SK-2) on a bush. Investigation in adaptibility of lovage and motherwort plants confirms genotypic variability of formation of productivity and influence of clima­tic conditions on these processes. Conclusions. Studying gene pool of Levisticum officinalis C. Koch and Leonurus guinguelobatus Gilib in conditions of Zakarpattia has shown that these crops are perspective for growing in conditions of low zone.
