Morphologigal Characteristics of Seeds of Some Iris L. Species in Saratov Region


The research presents the results of morphological study of seeds belong to five species of Iris L.: I. aphylla L., I. halophila Pall., I. pseudacorus L. I. pumila L., I. sibirica L. which existed in Saratov region and cultivated in the botanical gardens of national research of Saratov state university, previously named «N. G. Chernyshevsky». Photos were submitted for entire seed, seed coat sculpturing, outer epidermis of seed, hilum, longitudinal and cross section of seed, endosperm and embryo, morphometric characteristics which includes length, width and mass of the seeds also presented, Estimated morphological characteristics of seeds such as form, outer surface patterns, form and dimensions of hilum, position and dimensions of embryo and endosperm form. The colors of the seeds ranges from Cream to dark brown color , including copper shades; seeds form quite diverse (ovoid, obovoid, orbicular, hemispherical, conical, tetrangular compressed form, ovoid with cristiform outgrowth ); Outer surface of seeds was vary from smooth surface, rugose, ruminate, pitted and finely tuberous (In Iris halophila the outer layer is like a transparent membrane surrounding each seed), small hilum with rounded, ellipsoid and sometimes elongated shape, linear embryo and located at the base of seed (basal position) in all five species, small or medium embryo
