Особливості будови плодів і онтогенетичного розвитку Tetragonia tetragonioides (Pall.) O.Kuntze (Tetragoniaceae Nakai)

Abstract

The peculiarities of fruit structure and stages of ontogenesis in Tetragonia teragonioides (Pall.) O. Kuntze have been studied. The type of the fruit has been specified: many-stoned pyrenarium with a dry pericarp. Under Donbass’s conditions in ontogenesis only three periods are distinctly pronounced: latent, pregenerative and generative. Peculiarities of ontogenetic development testify to the species being ancient.
