Biomorphological features of 14 rare Tulipa species listed in the Red Book of the Republic of Uzbekistan (Tulipa affinis, T. carinata, T. ferganica, T. fosteriana, T. greigii, T. ingens, T. kaufmanniana, T. korolkowii, T. lanata, T. micheliana, T. scharipovii, T. tubergeniana, T. uzbekistanica and T. vvedenskyi) were studied under ex situ conditions in the Tashkent Botanical Garden. It has been found, that all studied species successfully grow and bear fruits ex situ. All 14 species are able to autogamy; even solitary generative specimens regularly produce seeds. This feature significantly facilitates the further breeding of rare species of tulips. Considering the heterospermy and irregular quality of seedlings, the most rapidly developing individuals should be selected for cultivation and reintroduction.

The issue of the conservation status of Euphorbia glareosa Pall. ex Bieb. (Euphorbiaceae Juss.) on the territory of the Republic of Bashkortostan is considered in the article. In the second edition of the Red Data Book of the Republic of Bashkortostan [2011] this species was included in the regional list of rare species that need biomonitoring – «List of objects of flora and fungi that are not included in the Red Data Book of the Republic of Bashkortostan, but need special attention on the territory of the republic to their state in the natural environment and monitoring». The article provides the following information about the species: morphological description with an indication of the main diagnostic features; modern data on the distribution of the species in the republic; brief ecological and phytocenotic characteristics; features of biology (according to data from literature sources); modern data on the number and state of local population; limiting factors; adopted and recommended protection measures, data on the possibility of preserving the species in culture. On the territory of the Republic of Bashkortostan, the species E. glareosa достоверно is known only from one point – the southern shore of Lake Aslikul in the Davlekanovsky district (the territory of the Asly-Kul natural park). In the republic, E. glareosa is a poorly studied species and is located at the edge of the range (at the eastern and northern limits of distribution). The known population is small 50-80 generative individuals). The population is subject to negative anthropogenic and natural influences. The species is poorly resistant to these influences. The species is on the verge of extinction. The data presented in the article fully justify the possibility of excluding the species Euphorbia glareosa Pall. ex Bieb. from the regional list of rare species «List of objects of flora and fungi that are not included in the Red Data Book of the Republic of Bashkortostan, but need special attention on the territory of the republic to their state in the natural environment and monitoring» and including it in «List of objects of flora and fungi listed in the Red Data Book of the Republic of Bashkortostan» (third edition, 2021) (category and status: 1 – endangered species).

The conservation of phyto-diversity should be based on original data on the structure and condition of natural populations, plant biology and ecology. The purpose of this study is to identify and compare regional features of the ontogenetic structure and state of coenotic populations of the rare species of the Southern Urals and Middle Volga Dictamnus gymnostylis (in the Samara Region and the Republic of Bashkortostan). In the Republic of Bashkortostan 20 geographical populations of the species are currently identified. In the Samara Region various published sources indicate 7-12 geographical populations of D. gymnostylis . The demographic structure, density of coenopopulations and habitat characteristics were studied with the use of traditional research methods in 18 trial plots: 9 in the forest-steppe zone of the Samara Region (Zavolzhye) and 9 in the southern forest-steppe zone in the Republic of Bashkortostan. Populations of the species were recorded in various types of communities: mainly meadow and shrub steppes, at the edges and under the canopy of oak groves. The number of populations in Bashkortostan is different: they number from 70-100 to 2000-5000 or even more. Presumably, the total number of species in the region is from 15 to 20 thousand copies. The total area of all known populations in the Samara Region is estimated by us at 5 hectares. The total number of individuals is approximately 2000-3000. Most of the coenopopulations of D. gymnostylis in the region are normal, incomplete. The absence in the spectrum of regenerative stages (seedlings and juvenile), as well as senile plants is typical. The absolute maximum falls on middle-aged generative individuals (24,1-59,0%). Almost all cenopopulations in the Samara Region are mature, and in Bashkortostan they are young (with a large share of regenerative plants). The recovery index is equal to or close to zero in the Samara Region; seedlings and juvenile plants are often absent here. In cenopopulations of the Republic of Bashkortostan, the recovery index in most cases is opposite to unity, which indicates a good replenishment of the population by young individuals. The aging index throughout the territory is close to or equal to zero (does not exceed 0,05). The state of the examined populations in Bashkortostan does not cause concern for their safety, but in the Samara Region they are vulnerable and require protection.

Data of long-term researches (2015–2018) in southern forest-steppe zone of the Republic of Bashkortostan, is justified theoretically and experimentally the mode of irrigation of potatoes on leached chernozems of unsatisfactory, satisfactory and good ameliorative condition of irrigated lands. For the growing periods of potatoes with different heat and moisture supply, the number of watering, the timing of their implementation, irrigation and irrigation norms are established. On lands with unsatisfactory meliorative state the number of irrigation depending on weather conditions of potato vegetation period varied from 0 to 3 (1.5 on average) with average irrigation norm – 990 m3/ha. With satisfactory meliorative state of lands the number of irrigation on average increased from 0 to 4 (2.3 on average) with irrigation norm – 1305 m3/ha. On lands with good meliorative state the number of irrigation was the highest – from 1 to 5 (3 on average) with average irrigation irrigation norm is 1653 m3/ha. It was noted that in the dry periods of potato vegetation the greatest number of watering was carried out (3–5 watering), and in the wet periods (2017) watering was not carried out except for the area with a good reclamation state, where only one irrigation was carried out by the norm of 550 m3/ha. Water consumption of potato was studied in dynamics as a whole during the growing season and the months of the growing season depending on weather conditions of vegetation period and land reclamation condition of irrigated lands, as well as in the control (without irrigation). The lowest total water consumption was in the area without irrigation and averaged 226.8 mm. In irrigated areas, its values increased to 319-353.4 mm. The average daily water consumption varied from 2.12 to 3.3 mm. The highest rates of potato water consumption were observed in June and July, and the lowest – in May and August. In the total water consumption of potatoes on the site without irrigation, the largest share was occupied by atmospheric precipitation and in addition to them the arrival of moisture from the soil. Irrigation water was used in irrigated areas along with precipitation, the share of which was 30.2–46.1 %.
