Abstract

This article presents the results of microscopic studies of the vegetative organs of natural species from Mangystau Region, Althaea officinalis L. and Malva thuringiaca (L.) Vis. (Malvaceae), which were introduced there under conditions of the Mangyshlak Experimental Botanical Garden (MEBG) (city of Aktau). The anatomical structures of the leaf, stem, and rhizome have been studied. Both species are characterized by a similar structure of the vegetative organs. The leaf, stem, and rhizome of A. officinalis are larger than the respective microstructures of M. thuringiaca, which can be explained by differences in the species ecology. The following diagnostic features have been proposed: arrangement of trichomes, mesophyll thickness, and placement of druses for the leaves; thickness of the cortical parenchyma and shape of the sclerenchyma areas for the stem; and thickness of the cortical parenchyma and presence of one- or two-row core rays for the rhizome. Species differences have been established in the number of layers of the palisade leaf tissue; the size and arrangement of star-shaped trichomes and the shape and arrangement of calcium oxalate druses; and the ratio of the spongy and palisade mesophyll. Differences in the structure of the transverse sections of the stem have been revealed in the thickness of the cortical parenchyma and shape of the sclerenchyma areas.

芒竹地区引种的杜鹃花和苏云金Malva的营养器官比较解剖学分析

摘要本文介绍了芒吉斯州地区天然植物Althaea officinalis L.和Malva thuringiaca (L.)营养器官的显微研究结果。在Mangyshlak实验植物园(MEBG)(阿克套市)的条件下引进的Vis. (Malvaceae)。对其叶、茎和根茎的解剖结构进行了研究。两种植物的特点是营养器官的结构相似。officinalis的叶片、茎和根茎的微观结构均大于thuringiaca，这可能与物种生态学的差异有关。提出了下列诊断特征:毛状体的排列、叶肉的厚度和叶片的结节的位置;茎皮层薄壁组织的厚度和厚壁组织的形状;根茎皮层薄壁的厚度和一排或两排核心射线的存在。栅栏叶组织的层数已经确定了种间的差异;星形毛状体的大小和排列以及草酸钙药物的形状和排列;海绵状叶肉与栅栏状叶肉的比例。茎横切面结构的差异体现在皮层薄壁组织的厚度和厚壁组织区域的形状上。

期刊介绍： Contemporary Problems of Ecology is a multidisciplinary periodical that publishes original works on the following subjects: theoretical and methodical issues of ecology, regional aspects of ecology, regional ecological disasters, structure and functioning of ecosystems, anthropogenic transformation of ecosystems. All basic aspects of modern ecology, including the most complicated interactions between living organisms and their environment, are presented. Some of the journal issues are dedicated to global changes in biological diversity at various levels of organization (populations, species, ecosystems) principles and methods of nature conservation.
