for the first time, work was carried out on the vegetative reproduction of Weigela florida f. “Bristol Rubru” (Caprifoliaceae) was introduced into the Tashkent Botanical Garden (Uzbekistan) through green branches. As a result of the research conducted, it was noted that the vegetative reproduction possibilities of the “Bristol Ruby” form of Weigela florida were high. Wn>hen placed on stimulants of two types (kornevin, heteroauxin), it became known that kornevin stimulants are effective in taking root. It was found that the effective way to multiply this form by green branches in a vegetative way—when placed on the stimulator of kornevin from the middle part of the rod, the indicators of root extraction of the cuttings were 93.3%, which is more effective than other options. When vegetative reproduction of this decorative form, it is recommended that the seedlings come to the standard state in 3 - 4 years and the root extraction indicators are high—this is its use as the second row shrubs in the case of growing on strongly saline soils in the conditions of Uzbekistan. The cultivation of green cuttings of the form in the fog showed that they are more effective than in the open ground.

Seed germination (in laboratory and field conditions) and vegetative reproduction (by cuttings) of a promising decorative species—Lonicera tatarica L. (Caprifoliaceae Juss.) was studied for the first time in the conditions of introduction of the tashkent botanical garden of Uzbekistan. Thus, the optimal temperature for germination of L. tatarica seeds in laboratory conditions is +20°C + 22°C, at which germination was 73%. The germination rate of seeds sown in autumn in the field was 62%, and the germination rate of seeds sown in spring was 71%. It was noted that in greenhouse conditions at an air temperature of 20°C - 22°C and a relative humidity of 49% - 53%, the rootability of cuttings was 75%. It was revealed that the studied species adapted well to the conditions of introduction. Taking into account the effectiveness of vegetative reproduction of L. tatarica, it can be recommended for improving the aesthetic condition and landscaping of cities, landscaping and landscape design.

first studied the anatomy of the leaf Allium suworowii in different ecological conditions: Jizzakh region and the tashkent botanical garden named after academician f.n. rusanov at the Institute of Botany of the Academy of Sciences of the Republic of Uzbekistan. Identifying diagnostic signs of the leaf and determining a different combination of xeromorphic and mesomorphic features ensure adaptation to habitat conditions. Under the conditions that nature mesomorphic signs predominate, and introduction-xeromorphic signs prevail, this indicates that they are adapted to the conditions of introduction of this species.

作者： nargiza K. Rakhimova Guljan M. Duschanova Sodikjon Kh. Abdinazarov Eldor E. Temirov Sobitjon S. nosirov Ismat n. Samadov laboratory Anatomy and Cytoembryology of the tashkent botanical garden named after academician f.n. rusanov Institute of Botany of the Academy of Sciences Tashkent Uzbekistan

The anatomical structure of the leaf of the Central Asian endemic species of Juno vicaria, growing in two different ecological conditions (Baysun Mountains of Surkhandary region and tashkent botanical garden of Uzbekistan) was analyzed and diagnostic signs were determined. Also identified are adaptive mesomorphic and xeromorphic signs from an environmental point of view. A species that grows in natural habitat is dominated by more xeromorphic signs: a thickened outer wall of the epidermis;numerous epidermal, spongy cells;submerged stomata;small, multi-row sclerenchymal and collenchymal cells, which indicate a more xeromorphic and adaptability, as well as the wide distribution of this species to the natural growing conditions. In a species growing under the conditions of introduction of the tashkent botanical garden, more mesomorphic features predominate: thin-walled, large, few epidermal, spongy cells;not immersed stomata;large non multi-row sclerenchymal and collenchymal cells, which show that the species is adapted to altered habitat conditions.

Central Asia is one of the main centers of origin of bulbous geophytes, including the family Amaryllidaceae Juss. The anatomical features of many endemic, red-book bulbous geophytes are still poorly understood. The article presents the results of a structural study of the inflated part of the stem (fistular), stem and pedicels of an endemic A. praemixtum species grow in two different environmental conditions in the Aktau mountain nurata Range (Uzbekistan, Province navoi) and in the conditions of introduction in the tashkent botanical garden (Uzbekistan, tashkent city). Diagnostic signs of vegetative organs were revealed and various combinations of xeromorphic and mesomorphic signs were determined. Comparative anatomical study of vegetative organs of A. praemixtum is of great theoretical and practical importance in relation to taxonomy and ecology.
