Saribaeva Sh.U., Shomurodov H.F., Abduraimov O.S. ONTOGENESIS AND ONTOGENETIC STRUCTURE OF COENOPOPULATIONS OF THE ASTRAGALUS HOLARGYREUS BUNGE (FABACEAE), NARROW-LOCALITY ENDEMIC OF KYZYLKUM // Arid ecosystems. 2022. V.28. № 1 (90). P. 91-97. | PDF

Analysis of the current state of the narrow-local endemic of the Kyzylkum Astragalus holargyreus showed that the studied coenopopulations are normal and incomplete. The study showed coenopopulations of A. holargyreus are normal and incomplete. The age spectrum of the first coenopopulation responds to the characteristic spectrum and reflects the biological features of the species: a gradual increase in life expectancy in the juvenile fraction and generative periods with a culmination in the middle-aged state, rapid aging. The ontogenetic spectrum in the second coenopopulation does not coincide with the characteristic spectrum. According to the amount of the points of organism and population signs, all the examined coenopopulations are in a stable state.

Keywords: ontogenesis, Kyzylkum desert, Astragalus holargyreus, Bukantau range, ontogenetic structure, coenopopulation.

Financing. The work was carried out with the support of the project of the Ministry of Innovation of the Republic of Uzbekistan, scientific project No. P3-2014-0828163420 “Assessment of the state of coenopopulations of rare and endangered plant species of the remnant lowlands of Kyzylkum in connection with desertification”.
