The current state of.coenotic populations of.rare and endangered species of.Uzbekistan-Tulipa lehmanniana Merckl. is given. Within the western part of.the area (Kyzylkum desert) in dif.erent ecological and phytocenotic conditions, 8 coenotic populations of.the species were identif.ed. Based on the number of.organism and population traits, the current state of.coenotic populations of.the species was evaluated. It was revealed that the vast majority of.coenopopulations are in pessimal state. Coenopopulation only growing on the eastern part of.the mountain Kuljuktau was assessed as optimal.

In the period 2019-2021, two coenotic populations of.O. tavernierfolia were studied in different ecological and phytocenotic conditions of relic mountain Kuldzhuktau. Very rare species of the Kyzylkum. It is spread at the Kyzylkum: the Kuldzhuktau, near Ayak-Guzhumdy and Churuk (Bukhara region). Inhabits stony and gypseous slopes. There are three small populations can be found. Limiting factors: degradation of habitat as a result of overgrazing. Measures of protection: not protected. The article is devoted to the assessment of the current state of coenotic populations of the rarest southwestern Kyzylkum (Kuldzhuktau) Onobrychis tavernierfolia. It was found that the studied coenopopulations of O. tavernierfoliaf.nt-f.mily:Verdana;"> are normal and complete.

Salvia lilacinocoerulea Nevski (Lamiaceae) is an endemic to the Western Pamir-Alay mountain range. Usually it grows on eroded clay soils among sparse juniper f.rests in the middle mountain belt. Studied coenopopulations of.S. lilacinocoerulea are normal, but are not complete. Coenopopulations self.maintenance is carried out by the seed of.renewal. The characteristic spectrum of.S. lilacinocoerulea coenopopulation is centered, with a peak in the middle-generative individuals. In most cases, specif.c developmental spectrum of.coenopopulation does not coincide with the characteristic ones. The demography structure of.mostly investigated coenopopulations is satisf.ctory. The population growing on the grey clay soil, on strongly eroded slope among sparse juniper woodland was evaluated as critical due to absence in ontogenetic spectrum young individuals and small percentage of.generative plant as well.

Central Asia is considered to be the primary center of.origin and diversity f.r the genus Tulipa L. (Liliaceae). The article considers the species of.rare and endemic Tulipa L. species in the arid regions of.Uzbekistan. There are nine registered species of.the genus Tulipa. In the course of.the study, the demographic indicators of.the modern population of.39 populations were evaluated. 39 populations of.the studied species were identif.ed, most of.which grow in the composition of.the wormwood f.rmations characteristic of.the Turanian f.oristic province.

A new salty and sandy desert of.ca 5 million ha has emerged on the exposed Aral Sea bed. Every year, 170-200 tons of.salt and dust rise into the air and f.ll on the territory of.the Republic of.Karakalpakstan. A number of.experiments have been *** in order to study the salt tolerance of.plants and select drought- and salt-resistant plant species, which show a wide ecological range, to f.x quick-sand dunes on the exposed Aral Sea bed. Among the studied species of.Calligonum genus C. caput-medusae Schrenk was the most resistant to the saline solution. At the end of.the vegetation experiment, the survivability of.individuals constituted 44.1% at the concentration of.1.0% of.sodium chloride. Artemisiaf.rganensis Krasch. ex Poljak. and Salsola richteri （Moq.） Kar. ex Litv. showed a good resistance to the concentration of.saline solution as high as 150 ram, at which no dried plants were recorded. As the concentration grew to 300 mM, the survivability of.Artemisiaf.rganensis dropped to 40.0% while 66.7 Salsola richteri individuals were developing successf.lly. An almost similar result was obtained during the experiment on Nitraria schoberi L.. The survivability of.rascheninnikovia ewersmanniana （Stschegl. ex Losinsk.） Grub. individuals signif.cantly decreased at the concentration of.200 mm （33.4%）, while f.r Agropyron cristatum the concentration of.300 mm was threshold, at which the survivability of.individuals was below 3.3%. The most resistant to the def.ation of.sands on the exposed bed were Salsola richteri and Calligonum caput-medusae, whose survivability on the sandy dunes was 17%-41%.

Correlations of.soil properties and f.uit size of.Calligonum mongolicum Turcz. and related species were analyzed. The resullLs showed that the particle size characteristics of.soils f.r growing Calligonum mongolicum and related species were similar, and the soils belonged to sandyones. The organic matter contents of.soils were low （averaging 1.772 to 3.054 g/kg）, and the total salt content of.soils was low too （averaging 0.471 g/kg）. The pH values indicated that the soils were alkaline, varying f.om pH 7.65 to 10.25. The results of.Principal Component Analysis （PCA） and hierarchical cluster showed that 9 habitats could be divided into 6 types according to salt contents and pH values. f.uit sizes of.dif.erent populations and the soil properties had signif.cant linear correlations （P〈0.000）. It was concluded that the dif.erences in f.uit sizes among the populations of.Calligonum mongolicum and related species werre related to soil variability, especially the nutrient contents of.soils, and f.uit size can not be considered as a taxonomic index of.Calligonum mongof.um and related species.

The article presents the composition and current state of.poisonous plants distributed on the Ustyurt plateau. Ustyurt is one of.the largest deserts in Central Asia, dif.ering f.om other deserts of.the world in geographical location, relief. f.ora and f.una and other f.atures. The territory of.Ustyurt occupies 21.3 million hectares, of.which the Karakalpak part accounts f.r 7.2 million hectares. Poisonous alkaloid-bearing plants of.the Karakalpak part of.the Ustyurt plateau Anabasis aphylla, Atriplex f.abellum, Kalidium capsicum, Salsola arbusculaef.rmis, Salsola f.liosa, Aellenia subaphylla, Anabasis brachiata, Rheum tataricum, Capparis spinosa, Glycyrrhiza aspera. Alkaloid-bearing plants that are not eaten or poorly eaten by cattle Ephedra distachya, Delphinium songaricum, Anabasis salsa, alkaloid-bearing plants eaten by animals without harm Carex physodes, Eremopyrum orientale, Agrophyllum repens, Astragalus amodendron, Astragalus villosissimus, species of.the genera Calligonum, Salsola. Poisonous plants of.the Karakalpak part of.the Ustyurt plateau. An analysis of.the pasture f.ora of.the Karakalpak part of.the Ustyurt plateau shows that 62 species of.wild poisonous plants belonging to 49 genera and 19 f.milies grow here. Although these plants are considered poisonous, but in modern pharmaceutics and medicine, they are used as medicinal.
