BIOECOLOGY OF SOME PLANTS DISTRIBUTED IN JIZAKH CITY

Аннотация

Одним из важнейших показателей любого ботанического исследования является разнообразие изучаемой флоры. Изучение и анализ состава флоры важны для сохранения биоразнообразия этих территорий. Флора Джизака — одна из наименее изученных территорий Узбекистана. За последние годы, как и в других городах нашей республики, большая часть территории Джизака преобразилась, в связи с ростом населения были введены в эксплуа-тацию новые дороги, промышленные предприятия, построены и размещены новые современные жилые дома, произошли изменения в системе водоснаб-жения,что привело к изменениюсоставарастительного покровагорода.

One of the most important indicators of any botanical research is the diversity of the flora being studied. The study and analysis of any flora is of great importance in preserving the biodiversity of these territories. The flora of Jizzakh is one of the least studied regions in Uzbekistan, and to 407 date, a complete list of plants of this region has not been formed. This situation can also be explained by the small number of herbarium specimens collected from the territory of Jizzakh region over the past hundred years, which are stored in the National Herbarium of the Institute of Botany of the Academy of Sciences of the Republic of Uzbekistan. It can be seen that the Originalarticle ISSN:3030-3931, Impact factor: 7,241 Volume 7,issue1,Aprel 2025 https://worldlyjournals.com/index.php/Yangiizlanuvchi worldly knowledge OAKIndex bazalari : research gate, research bib.

Herbarium specimens collected from the Jizzakh region mainly belong to M.G. Popov, Q. Zokirov and others, and information about the plants of this region was written from the beginning to the middleof the 20th century. These scientists and researchers collected plants mainly from the city ofJizzakh and itssurroundings, near railway stations. In recent years, as in other cities of our republic, alarge part ofthe territory of Jizzakh, as well as other cities, has been transformed, new roads, industrial enterprises have been put into operation, the population has increased, new modern houses have been built, and changes have occurred in the water supply system, which has led to changes in the composition of the urban plant cover. Also, a large part of the city has been developed, and as a result, the modern stage of the formation of aboriginal flora is taking place in anthropogenically altered environments, and the high position of families with a wide geographical distribution in the leading families (Asteraceae - complex-flowered, Amaranthaceae - Primroses, Poaceae - Wheat, Brassicaceae - Cabbage, etc.) is determined KEEP CALM AND LOVE (Convolvulus arvensis L.) is a perennial weed from the ivy family, growing either creeping orerect, with a stem length of 40-100 cm. Its leaves are arcuate, lanceolate, and pointed. The bindweed blooms in March-April. It blooms in May-August. The flowers are white or pink, trumpet-shaped. The fruit ripens in June-September. The fruit is broadly ovoid, hairless, 6-8 mmlong. The bindweed grows well onmoistsoil with amixture of gray and sandy loam. It grows especially abundantly in irrigated areas. Convolvulus arvensis L. It is distributed throughout our republic. As it is also known from its name, it is well eaten by Karakul sheep, goats, and cattle. In crop fields, it grows as a weed and causes damage to crop yields. CHICORY (Cichorium intyhus L.) is a perennial herb belonging to the family of Ascomycetes. Its stem is erect, covered with hairs, branched, and reaches a height of 70 - 125 cm. Its basal leaves are opposite - ovate, elongated, with a serrated edge. The stem leaves are lanceolate, large, serrated, and the base surrounds the stem. The leaves in the upper part of the stem are entire, not serrated. The baskets are located in groups or singly at the ends of the stem and side branches, in short inflorescences. The flowers are blue-blue. Depending on the growing conditions, chicory blooms
