For the first time in the conditions of the Tashkent Botanical Garden, the daily and seasonal dynamics of flowering of Lonicera korolkowii Stapf, depending on temperature and relative humidity, were studied. According to two year (2022-2023) comparative results obtained on the dynamics of flowering, in 2023, compared with 2022, the beginning of the flowering phase was observed 8 days earlier (28.03) (air temperature 27 °C, relative humidity 34%) and the end of flowering – 5 days earlier (14.04). This is due to an increase in air temperature (up to 33 °C) in 2023 compared to 2022 (14 °C, 47%). This also led to an increase in the seed productivity of the species, that is, in 2023, the seed productivity coefficient was higher (86.4%) than in 2022 (72.0%). The study of the dynamics of flowering and seed productivity of Lonicera korolkowii in the conditions of introduction allows us to determine in which areas or in what quantities the studied species can be used in the future, when introduced into forestry, landscaping or greening cities. Abundant flowering and fruiting in the Tashkent Botanical Garden is a sign of successful adaptation to the conditions of introduction. In this regard, the plant can be recommended as an decorative species in the landscaping of the cities of our republic.
