The region's aquatic vegetation of lake Kara-Kira Bukhara

The study of high water plants was carried out in complete field conditions. At the specified points, the associations formed by water plants were determined. The northern collector is the main source of water in the lake. Although water is not taken from the lake, the amount of water decreases because of the evaporation and filtration. A large amount of biomass is also formed by plants that grow under water. Several species of Rdest give tons of biomass during the period of vegetations. The composition of the plants, whose names are mentioned above, consists mainly of carbohydrates. The most common in the lake is a simple Reed, a plant that spreads and forms large fields. The length of its stem is 2–4 meters. The biomass that forms the cane depends on the depth at which its stem is located in the water. Of the collected samples, 0,05 ml of water was taken, poured onto the garyaeva chamber, and the top cover was closed with a mirror. The prepared drug was seen in a microscope and the dominant types of phytoplankton were determined using speculators. In the territory of Bukhara region there are 7 natural lakes, all of which are formed on the account of collector waters. The total area of these waters is 101 thousand hectares. The maximum depth of Kara kir Lake is 5–10% of the total area, the average depth is 15–20%, the minimum depth is 70–80%. In summer and autumn, the shallow areas of the lake dry up and eftrophication is observed.
