Abstract
The paper presents the results of studying the decorative species Crocus speciosus. Some features of the formation and development of male and female generative spheres are presented. It is shown that the formed anther wall is generated by the epidermis, endothecium, middle layer and tapetum. The wall of the mature anther is formed by the epidermis, fibrous endothecium with fibrous thickening, and a tapetal spathella with sporopollenin orbicles. Analysis of mature pollen grains showed a rather high proportion of normal pollen grains (80%), which under favorable conditions indicates a high ability to effectively pollinate. The characteristics of the female generative sphere are also shown: three-celled ovary; anatropic, bitegmal, funicular, crassinucellate ovule; linear tetrad of megaspores; Polygonum-type of embryonic sac development. The processes of flowering, pollination and seed formation are described.
