The genesis of leaves in the Apiaceae family.
IN most cases the leaves of representatives of the Apiaceae L. family are considered to be simple in the botanical literature (Flora of the USSR, 1950), but we have found out that the majority of leaves formed during ontogeny of more than 30 genera of representatives of the subfamily Apioideae are compound. The comparison of morphogenesis of leaf stages has allowed us to establish that the subfamilies Apioideae and Saniculoideae are the most similar due to a complex of morphological attributes of vegetative body structures, and these subfamilies essentially differ from the subfamily Hydrocolyloideae. Investigated representatives of the subfamily Apioideae display greater heterophylly, and this level of variability in leaves is typical for the other subfamilies. During the study of leaf morphogenesis in various species of the subfamily Apioideae, it has been determined that this process is not uniform, and the typology of leaf genesis has been developed on this basis. We offer five types of morphogenesis (namely: Apium-, Levisticum-, Conium-, Petroselinum- and Chervil-types), that take into account differences in the organogenesis process of compound leaves.[c.e.:srb]
