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. When 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.
