Correlation dependences of economical and valuable signs in Serratula coronata L

The research objective was to define correlation depend-ences of economical and valuable and separate quantitative signs of the herb of Serratula coronata L. Correlation analysis was carried out according to biometric supervision and the results of accounting of raw materials productivity and seeds and the results of chemical analysis L in 2014-2016 while studying Serratula coronata L population., cultivated in Mos-cow Region. Biomorphological observations were made on individual plants (45 plants or bodies of plants). Elevated part of Serratula coronata L. was prepared in the phase of the beginning of blossoming. The productivity of raw material was evaluated in traits of leaf formation, the number of shoots, dry mass of the shoot and dry weight of elevated parts of plants. Leaf formation of the shoots was determined by numerical method (in per cent) in 45-50 shoots as the relation of the number of leaves to the length of leaf part of the shoot. Leaf formation was determined by weight method (per cent) as the relation of the mass of fraction of leaves to the lump of ele-vated part (by dry weight). The crop of raw materials of ele-vated weight depended on the height of the plant, the number of shoots on the plant and leaves determined by weight method (r = 0.49-0.68). The maintenance of ecdysterone was connected with the length of shoot leaves (r = 0.33-0.48). Average positive correlation of quality of raw materials (ac-cording to the content of biologically active agents) and productivity of raw materials (r = 0.52) showed that the sam-ples with the greatest maintenance of ecdysterone could be allocated in the populations with high productivity of elevated weight. The crop of seeds depends on the number of shoots and inflorescences (r = 0.56 and r = 0.90 respectively), and this dependence amplifies from the 3-rd by 5-th year of life. The results of the research are actual in aspect of creation of improved, initial and selection material of Serratula coronata L. The obtained data will allow revealing the signs for selec-tion of productive morphotypes.
