【 摘 要 】

The results of biological testing of pale coneflower extract on hormone-like substances was given. With the help of specific tests, it was found that extract of pale coneflower have the activity similar to main groups of hormones. We founded the auxin-like effect of extract which exhibit in increased area of growth zone of root (on 31,7–95,1%) and length of roots in beans sprigs (3,0–93,3 %). We also proved that the extracts of pale coneflower in concentrations up to 10 -10 % stimulated the growth of dwarf pea shoots (specific test for gibberellins) and contributed to the preservation of photosynthetic pigments in leaves of barley. We suggested that this cytokinin-like activity.Keywords: pale coneflower, hormonal activity, auxins, gibberellins, cytokinins, extract, biological test (bioassay).
