Abstract

In work the ecological features of milkweed (Asclepias syriaca L.) distribution within thePoltava region have been established. Milkweed has been shown to be  dangerous  contaminator of agricultural crops within thePoltava region. Assemblages of this weed in agroceonosis were generated at the expense of seeds which it is constantly brought on fields from not treated lands, and also with insufficiently cleared organic fertilizings. For growth milkweed fields which certain time were in agricultural using are especially congenial and is temporary, or for ever, withdrawn from it. On ecological properties of milkweed is perennial, rootspout, vegetation moving, geophyt (wintering points of restoration are underground), mesotroph, mesophyte, megaterm, scyogeliophyt, entomophyl (pollinating descends by means of hexapods), an anemochore, ruderant. Milkweed very quickly extends along highway and soil pathes, occupying new areas and geographic ranges. On roadsides of tracks of the report specific conditions of medium are created. Less competitively the capable vegetation which existed before, is submitted to mechanical influence, degrades or is completely destroyed.
