FLORISTIC COMPOSITION OF HONEY PLANTS OF THE FERGANA VALLEY AND WAYS OF THEIR RATIONAL USE AND PROTECTION
The species composition of melliferous plants of the Fergana Valley, and their patterns, distribution and resources, as well as the nectar productivity of species, and determination of the sugar content in nectar, the most nectar productive species, have been revealed. A list of the melliferous flora of the Fergana Valley has been compiled and analyzed, numbering 490 species and 277 genera. A list of the most nectar-producing species, genera and families of plants has been determined. The largest families of melliferous plants in the Fergana Valley are: Asteraceae, Rosaсeae, Fabaceae. Suppressing most species, they provide bees with nectar and dust at the same time. Flowers in the majority of melliferous species produce from 0.02 to 0.40 mg of nectar per day, up to 1.60 mg, and only two representatives of our flora emit up to 1 mg. Due to the variety of climatic and other natural conditions, including melliferous flora, they are distributed in the following vertical-high-altitude zones: desert, foothills, mountains and highlands. The richest in species composition and nectar productivity of the melliferous flora are found in the mountainous zone, the least in the desert and alpine zones. Large families of melliferous plants: Lamiaceae, Brassicaceae, Liliaceae, Apiaceae, Boraginaceae, Alliaceae, Scrophullariaceae, Chenopodiaceae, Papaveraceae, Rununculaceae.
