Apomixis in Anthoxanthum nitens and A. repens (Poaceae L.) in the Saratov region flora

The article presents the results of cytoembryological analysis of four cenopopulations of two Anthoxanthum L. species from the fl ora of the Saratov region: A. nitens (Weber) Y.Schouten & Veldkamp and A. repens (Host) Veldkamp. Embryological characters of Hieracium-type apospory and pseudogamy were recorded in plants of both species: (1) formation of several eight-nucleate seven-celled embryo sacs in the ovule; (2) development of the proembryo in unfertilized megagametophytes with intact polar nuclei.
