Abstract

Despite of the increasing functional and molecular studies in the sunflower family (ASTERACEAE), the study of generative biology that consists of flowering DEVELOPMENTal stages in necessary. In this research, Embryological characteristics including of OVULE and POLLEN GRAINs DEVELOPMENT of ECHINOPS ILICIFOLIUS from ASTERACEAE family were studied. The flowers and buds in different DEVELOPMENTal stages were removed, fixed in FAA70, stored in 70% ethanol, embedded in paraffin and sectioned with a thickness of 5-7 μm by microtome. Staining was carried out with Eosine and Hematoxylin. Then slides were studied using light microscope and were photographed. Results indicated that anthers were Tetra-Sporangiate and tapetum was of the periplasmodial type. Pollen tetrads were tetrahedral and tetragonal. In anther tissue interface particles were crystalline needles. POLLEN GRAINs were 2-celled at the time of Diffusion. OVULE was anatropous, unitegmic and tenuinucellate. Endothelium was uniseriate and connected with embryonic sac. Embryo sac DEVELOPMENT was of the Polygonum type Antipodal cells increased up to 6-8.
