THE TERATOGENIA AND THE EVOLUTION OF CRUCIFERAE


V.I.Dorofeev, Komarov Botanical Institute, St. Petersburg, Russia


There are lot of terates of Cruciferae (more than 20 species) at ancestral and at juvinal tribes with anomal flowers and fruits. Very often it have same structures: 1) the petals and the sepals get the similar structure, 2) definitely the terat flower have gynophore, 3) the ovary of the species with silicule is longer that at the normal specimen and the ovary of the species with silique is shortly that at the normal specimen, 4) the style becomes much shorter. All these very evidence changes to us very remind the special group of genera from tribe Thelypodieae. The several relictes of this tribe there are in North Asia and in Europe. We know there are several species with gynophore from tribe Brassiceae, tribe Sisymbrieae, tribe Alysseae and other. Therefore, may be teratogenia help us to study the beginning stages of the evolution of Cruciferae.
