ABSTRACT: 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.
