Abstract

This article presents the results of a study of the state of the cenopopulation of a rare species, Allium praemixtum Vved. in the Nurata and Turkestan ranges. The ontogenetic structure of the cenopopulation was studied by the generally accepted methods (Uranov, 1975; Tsenopopulyatsiya rastenii…, 1976). Cenopopulations were characterized according to the classifications of A.A. Uranov and O.V. Smirnova (1969) and “delta–omega” (Zhivotovsky, 2001). The ecological density was determined by the method of W. Odum (1986). Geobotanical descriptions were made according to the standard methodology on sites of 100 m² (Field geobotany, 1964). The characteristic ontogenetic spectrum is left-sided, with an absolute maximum in one of the pregenerative groups (Cheremushkina, 2004). Cenopopulations (CP) 1, 5, 6 correspond to the characteristic left-sided ontogenetic spectrum with a maximum peak in the virginal state of the species. The centered ontogenetic spectrum does not coincide with the characteristics, culminating in middle age. The bimodal ontogenetic spectrum is then considered as a temporary left-sided variant with an equal peak in the medium generative and virginal states. The density of individuals in the studied cenopopulations varied from 1.1 to 9.7 ind./m², and the ecological density is from 2.3 to 17.63 ind./m². According to the “delta-omega” classification Allium praemixtum cenopopulation CP 1 is maturing, CP 5 and 6 are young, CP 2 and 4 are transitional, and CP 3 is mature. Existing cenopopulations are mainly located on unprotected territory, with the exception of CP 3 (near Mazhrumsay) and 4 (near Gurdarasay). The only solution to this problem can be the strict protection of cenopopulations.

对 Allium praemixtum Vved 状态的评估。乌兹别克斯坦山脊上的新种群（石蒜科）

摘要

本文介绍了对稀有物种Allium praemixtum Vved的新种群状况的研究结果。在努拉塔和土耳其斯坦山脉。通过普遍接受的方法研究了新种群的个体发育结构（Uranov，1975；Tsenopopulyatsiya rastenii …，1976）。根据 AA Uranov 和 OV Smirnova (1969) 和“delta-omega” (Zhivotovsky, 2001) 的分类对新种群进行了表征。生态密度采用W. Odum (1986)的方法测定。地理植物学描述是根据标准方法在 100 m ²的地点进行的（Field geobotany，1964）。特征性个体发育谱是左侧的，在早生类群之一中具有绝对最大值（Cheremushkina，2004）。新种群 (CP) 1、5、6 对应于特征性左侧个体发育谱，在该物种的原始状态下具有最大峰值。中心的个体发育谱与特征不相符，在中年达到顶峰。然后，双峰个体发育谱被认为是临时的左侧变体，在中等生殖状态和处女状态下具有相同的峰值。所研究的新种群个体密度为1.1至9.7个ind./m ²，生态密度为2.3至17.63个ind./m ²。根据“delta-omega”分类，Allium praemixtum 新种群 CP 1 正在成熟，CP 5 和 6 处于年轻状态，CP 2 和 4 处于过渡状态，CP 3 处于成熟状态。现有的单胞种群主要分布在未受保护的地区，除了 CP 3（靠近 Mazhrumsay）和 4（靠近 Gurdarasay）之外。解决这个问题的唯一办法就是严格保护新种群。
