Abstract

The processes of formation of many species are observed in the south of the Central Russian Upland. For these conditions, the morpho-anatomical features of the tepals of Tulipa biebersteiniana Schult. Et. Schult. fil as the adaptive potential of seed propagation were studied for the first time. The tepals are arranged in two circles and differ in morphological and anatomical features. Differences in the structure of the main cells of the epidermis on the abaxial and adaxial sides were revealed. On the abaxial side, the main epidermal cells are rectangular, sometimes fusiform or rarely diamond-shaped, arranged in rows. They are covered with a weakly longitudinally wrinkled cuticle. The side walls of the abaxial surface are straight or slightly curved. On the adaxial surface, the side walls are zigzag, passing to the lateral edge in strongly sinuous. The localization, estimated functions and sizes of the hairs on the leaves of the tulip were determined. Single celled trichomes are located in two places.

Highlights

Landscape and climatic conditions of ecotopes of ravine-beam complexes with Cretaceous outcrops in the south of the Central Russian Upland form the conditions for the preservation and development of unique flora [1]
The study of the number and distribution of individuals by age groups indicates the stability of adaptive micro evolutionary changes occurring in populations [2,3,4,5,6], which allows us to consider the south of the Central Russian Upland to be a secondary anthropogenic microgen center of species formation [7,8,9]
The demographic strategy of the Tulipa biebersteiniana is associated with the implementation of seed and vegetative reproduction

Summary

Introduction

Landscape and climatic conditions of ecotopes of ravine-beam complexes with Cretaceous outcrops in the south of the Central Russian Upland form the conditions for the preservation and development of unique flora [1]. The East EuropeanAsian species is a stolon-forming ephimeroid-geophyte. It is found in shrubs, steppe areas, and forest edges. The demographic strategy of the Tulipa biebersteiniana is associated with the implementation of seed and vegetative reproduction. T. biebersteiniana plants are characterized by high potential and low real seed productivity [6]. Along with an increase in seed productivity at the organizational level, the habit of plants decreases, and stolon formation increases. The authors identified an attempt to assess the presence of morpho-anatomical features of the flower T. biebersteiniana in connection with the generative strategy, despite the absence or low real seed productivity
