“…Most of the species under study were planted on a plot partially shaded by trees and bushes. To study the leaf anatomy of rare and commercially valuable plants, we used a number of generally accepted methods (Belaeva et al, 2014). The stomatal index was calculated by Kästner's formula (1972).…”

In this research, we discovered a number of structural adaptations and informative characteristics for the leaf blades of the studied species from the genus Primula L. The species under study were found to have anomocytic stomatal type. The leaf blades are hypostomatic (P. denticulata) or with the predominant abaxial stomata (P. macrocalyx, P. pallasii). The following indicators have low variation): size of stomata, number of cells in the upper and lower epidermis, height of cells in the upper mesophyll layer, lamina thickness near the midvein and central part, phloem cross-section area, and vascular bundle area. High and very high variation level is observed for the quantitative indicators describing the leaf indument density, number of stomata and stomatal index of the upper epidermis. The data obtained can be used to evaluate the species adaptability and to develop the appropriate light and hydrothermal regime for cultivating the species in the Western Siberia sub-boreal forest environment.

“…Число клеток и устьиц на 1 мм 2 эпидермы подсчитывали после отделения кожицы в средней части листа. В качестве методической основы для изучения анатомического строения листовых пластинок растений использованы общепринятые методики, изложенные в статье Belaeva et al (2014). Устьичный индекс рассчитывали по формуле Kästner (1972).…”

This article contains a comparative analysis of the anatomical structure of the rosette and stem leaves of Echinacea purpurea and E. pallida. The plants were grown on the experimental site of the Siberian Botanical Garden, located in the southeastern part of Tomsk (Western Siberia). Temporary preparations of the leaves were prepared by cutting them on a freezing microtome MZ-2. Photographs of leaf microscopy and microscopic measurements were made on a light microscope. Anomocyte type of stomatal complex is characteristic for the studied species. Leaves of the studied species are amphistomatic, rosette leaves of E. purpurea are hypostomatic. The stomatal index of E. purpurea was 1.5 (stem leaves, upper epidermis) and 24.4–25.5 (lower epidermis). In the leaf blade of E. purpurea, the signs are revealed as mesomorphic (the presence of relatively large dorsoventral leaves, moderate development of integumentary, conducting and mechanical tissues) and a xeromorphic-heliomorphic structure. A complex of xeromorphic-heliophytic features of the E. pallida leaf has been identified, which increase its drought resistance; the mean values of the stomatal index of the upper and lower epidermis were 24.8–28.7. There are 10 characteristics that have significant differences in mean values when comparing leaves of E. purpurea and E. pallida: the size of the stomata of the lower epidermis, the thickness of the mesophyll of the leaf, its layers and the leaf laminae free of the vascular bundle, the area of the vascular bundle and their constituents.

Проведенное сравнительное изучение анатомии листьев Phlox sibirica и Phlox sibirica var. borealis позволило выявить, что морфометрические признаки строения листьев в 95 % случаев достоверно отличаются при уровне значимости P < 0,05. Статистически значимых отличий не было обнаружено только при определении устьичного индекса, значение которого также соответствует другим видам почвопокровных флоксов. Для изученных таксонов характерны закрытые коллатеральные пучки, аномоцитный тип устьичного аппарата и удлиненные, извилистые эпидермальные клетки. Phlox sibirica отличается большим развитием тяжей колленхимы, обеспечивающей жесткость листа даже при потере тургора, ксилемы, наиболее фотосинтетически активного слоя мезофилла (клеток верхнего слоя). Таким образом, в анатомическом строении листьев изученных флоксов выявлены признаки, свойственные для ксерофитно-гелиофитных видов, более выраженные у Phlox sibirica. Анатомия листьев изученных таксонов отражает их адаптацию к условиям с неблагоприятным водным режимом (обеспечивает поддержание нормального водного баланса) и избыточным освещением.
