Pikalova E.V. AMBROSIA TRIFIDA L. AT THE CONDITIONS OF THE TYULGANSKY DISTRICT OF THE ORENBURG REGIONIn this article considered a biological features of Ambrosia trifida L. The paper gives the results of studying morphometric parameters and reproductive performance of Ambrosia trifida L. at the example of one of the central districts of the Orenburg region. Differences in variation of signs are caused by climatic features of each particular area of research and ecological conditions of habitat of cenopopulations. The low variability index was marked in cenopopulations located along the roads, and the higher — in cenopopulations occupying shaded zones and lowlands with the dunged substratum. The general seed efficiency in three studied cenopopulations ranges from 303,3 to 472,8 pieces of seeds on the average on one plant.Key words: Ambrosia trifida L., morphometric parameters, coefficient of variation, seed production, cenopopulation, invasive species.
