Abstract: (6863 Views)
Some of ruderal and segetal areas inside of Hamedan city and its suburb (in a radius of 2o km) involving some of farms, gardens, green spaces, waste lands and also margin of terrific regions (streets and superhighways) were compared based on ecological-floristically view in relation to presence and dispersal of Heliotropium genus between 2010 -2011. This genus with 74 species is introduced as one of the Boraginaceae family genus for Iran, which have many species. Heliotropium europaeum L and Heliotropium noëanum Boiss. have been already observed in inside of Hamedan city and its suburb. Extensive dispersal of H. europaeum L. species with H 4, 5, 6 hemeroby degrees as an segetal-ruderal neophyte element, in humid areas (such as gardens, left farm lands, beside roads) and also in dry regions (such as between pavings and asphalts clef, beside of walls and etc.) indicates high adaptation of this species with many ruderal biotops inside of Hamedan city and its suburb. H. noëanum Boiss. with H4 hemeroby degree, was observed limitedly and only in one urban site and also in a few number in its suburb.
