Micro- and Macromorphological Features of Five Crambe Species Introduced in the M.M. Gryshko National Botanical Garden Nas of Ukraine

Objective: The aim of the study was to establish the micro- and macromorphological features of vegetative and generative organs of plants of species of the genus Crambe, depending on the specific characteristics of the introduction to the M.M. Gryshko National Botanical Garden NAS of Ukraine. Method: The study of vegetative and generative organs was performed by dissection. Exploration and photo-fixation of the microstructure and microsculpture of their surfaces were performed using а light USB microscope SIGETA Expert 10-300x 5.0Mpx, as well as a digital SLR camera Canon 400 D. In order to characterize vegetative and generative organs “Atlases on the Descriptive Morphology of Higher Plants” was used. The material for studying the anatomical features of cross-sections of petioles observed through an electric microscope was taken from the central part of petioles. Results and Discussion: The peculiarities of morphological structure of vegetative and generative organs, anatomical structure of leaves, micromorphology of leaf surface, microsculpture of fruit and seeds of plants of species of the genus Crambe under conditions of introduction have been established. Micromorphological and anatomical studies have revealed a number of traits that affect plant resistance to environmental conditions. Variations in density and nature of pubescence of leaves and stems in different species of the genus Crambe indicate their high adaptive potential. Conclusions: Thus, for the first time the micro- and macromorphological features of vegetative and generative organs associated with the resistance of plants of species of the genus Crambe to environmental conditions were established under the conditions of introduction at M.M. Gryshko National Botanic Garden of National Academy of Science of Ukraine. The plants have been divided into groups according to a range of micromorphological features, which can be further used in breeding and genetic work for the purpose of selecting economically valuable plant species to enrich phytocenoses in Ukraine.
