Analysis of the representation of species of the genus Allium L. flora of Aral-Balkhash region in the Herbarium (AA)

Abstract

The genus Allium L. has a large number of representatives in the flora of Kazakhstan. The ecological range of species of the genus extends from the alpine and subalpine belts to deserts. Species of this genus are characterized by a variety of morphological characteristics, which creates difficulties in their identification. according to modern data, 25% (18%) of the 140 onions growing in Kazakhstan have been found in Aral-Balkhash region. The purpose of the research was to critically study the collection materials of 15 species of the genus Allium from 3 sections (Haplostemon Boiss. – 7; Porrum Don – 3, Molium Don – 5), that were the most widely represented in the flora of the Aral-Balkhash region, stored in the Herbarium Fund of the Institute of Botany and Phytointroduction (AA). As a result of the herbarium specimens analysis, the locations of only 12 species of the genus Allium, given for the territory of the country, were revealed, one of which is included in the Red Book of Kazakhstan. As a result of the research, an annotated list of Allium species of Aral-Balkhash region presented in the Herbarium (AA) (Almaty, Kazakhstan) has been formed. It has been shown that the largest number of samples preserved in the collection falls on Betpakdaly, Moyinkum, Balkhash-Alakol floristic regions of Kazakhstan.
