Taxonomic morphological and anatomical study of fruits and seeds for different species of the family Brassicaceae in Iraq

Abstract

The research included five species are : Leptaleum filifolium (willd)Dc. , Malcolmia africana(L.) ,Matthiola longipetala (Vent.)Dc. , Neotorularia torulosa, (Desf.), Sisybrium irio (L.) , which grow wild in Iraq .and belonging to three different tribes which are (Hesperideae, Matthioleae , Sisybrieae ) to the Family Brassicaceae . The research covered the Morphological characters of the fruits ( Shape , color, Indumentums and dimension) as well as seed morphological characters ( Shape, color, surface configuration and dimension) , the anatomical studied include fruit parts ( beak, valve and pedicel ) Showed and there is difference in structure and arrangement of tissue part of their species . The research important and diagnostic value between in the species, as well as the thickness of the fruits coat and shape section importance in the separation between the species , The results anatomical study of seed coat there was a difference in number tissue layer different types of species. The study of embryos , was one of the first studies in Iraq about the shape and dimensions in this family to be of importance in the separation of the species. The results of the present study proved that species Neotorularia torulosa, (Desf.)Records distribution for the first time in Iraq absent mention advance in the Iraqi flora.
