In the case of cultivated plants, the phenomenon of plant development depends on air temperature and precipitation, and climatic parameters respond to plant phenomena. Therefore, the study of vegetative phenomena focuses on specific stages of regeneration, leaf decay, budding, flowering, end of flowering, fruit ripening and decay, and they are studied in relation to climate change and the duration of each stage of development varies. It is believed that the duration of plant growth is related to air temperature and precipitation. The study materials were selected from the seeds of Sophora flavescens Solander, a very rare, medicinal and edible Solander collected from Gurvanzagal soum, Dornod province in 2010. grown. The plant has a lifespan of 72% since planting and began flowering in the third year. 2017, and bean seed ripening in 2018, indicating that the plant is adapting to ex situ conditions. To study the average air temperature and precipitation of 2017-2020 and to determine the time from regeneration to leaf decay, the duration of growth, the duration of flowering, and the time of ripening of beans, the duration of growth is 119-123 days and the number of days with flowers is 18. -35 days, the number of days of soybean ripening was 20-28 days, the period of intensive growth was 35-52 days.
