Early Periods Of Ontogenesis Of Lycium Сhinense Mill., Introduced In Mirzachul, Khazratkul Kilichevich Karshibaev, Mavluda Amanova Jun 2021

Early Periods Of Ontogenesis Of Lycium Сhinense Mill., Introduced In Mirzachul, Khazratkul Kilichevich Karshibaev, Mavluda Amanova

Bulletin of Gulistan State University

The article is devoted to the study of the initial periods of the ontogenesis of the L. сhinense (dereza, Tibetan barberry, Goji, wolfberry) introduced in the Mirzachul conditions. The periodization was carried out according to the "Ontogenetic Atlas of plants", developed by the leader of L. A. Jukova (2007). When determining the boundaries of the age range of an person, the criteria proposed for flowering plants were used (L. B. Zaugolnova et al., 1988). L. сhinense is a perennial plants, deciduous shrub, reaching 1.2 – 2.0 m in height. The fruit is oblong in shape, 11-27 mm long and 7-11 …


The Seed Biology Of Some Fodder Legumes Plants (Fabaceae) In The Arid Zone Of Uzbekistan, Khazratkul Kilichevich Karshibaev, Jaxongir Khazratkulovich Karshibaev, Zarina Furkatovna Jumaeva, Farrukh Bakhrom Oglu Abdukholiqov Dec 2020

The Seed Biology Of Some Fodder Legumes Plants (Fabaceae) In The Arid Zone Of Uzbekistan, Khazratkul Kilichevich Karshibaev, Jaxongir Khazratkulovich Karshibaev, Zarina Furkatovna Jumaeva, Farrukh Bakhrom Oglu Abdukholiqov

Bulletin of Gulistan State University

The article provides information about the quality of seeds: infestation, germination, humidity and mass of 1000 seeds of some fudder legumes plants. The infestation of seeds in the studied species in natural conditions ranges from 16,9 to 22,4 %, and the moisture content of seeds was 12.9-15.4 %, depending on the species. Hard-seeding is very high, from 80.6 (O.micrantha) to 95.4% (A.sieversianus). Seed dormancy in the studied taxa according to the classification of M. G. Nikolaeva et al. (1985) belongs to the physical group of exogenous dormancy– Af. The rate of water intake to seeds largely depends on the heterogeneity …

Reproduction Characteristics And Seed Renewal Of Onobrychis Chorassanica (Fabaceae) In The Arid Zones Of Uzbekistan, Khazratkul Kilichevich Karshibaev, Zarina Furkatovna Jumaeva Sep 2020

Reproduction Characteristics And Seed Renewal Of Onobrychis Chorassanica (Fabaceae) In The Arid Zones Of Uzbekistan, Khazratkul Kilichevich Karshibaev, Zarina Furkatovna Jumaeva

Bulletin of Gulistan State University

The article is devoted to the reproduction processes and seed renewal of 3 senopopulations of O. chorassanica Bunge (SP-1: Yangiabad region, in the territory Khojamushkent forest districts; SP-2: Zaamin region, in the south of village Bolgali; SP-3: Zaamin region, in the territory Zaamin forest districts about village Ual) in the adir (semidisert) zones of Uzbekistan. This plant is a typical long-stem herbaceous polycarpic, xeromesophyte, heliophyte, hemicryptophyte, has an underground caudex storage organ – for the supply of nutrients and replenishment of buds. While studying the reproductive biology of plants the works of Ponomarev A.N. (1960), Satsyperova I.F. (1993), Ashurmetov A.A. …

Influence On The Growth And Development Of Tomato Planting Systems, Shuxrat Shavkatovich Toychiev, Аkmal Botirovich Xayriddinov

Bulletin of Gulistan State University

It is known that the sustainable development of each country depends largely on the availability of food products for the population. Our country has sufficient conditions to grow abundant and high-quality, affordable vegetables, melons and potatoes. Usually for sowing vegetables such as tomatoes, sweet peppers and eggplants, their seedlings are prepared first in greenhouses and then planted in open spaces. It should be noted that sowing tomato seeds in the open field is more effective than sowing. Temporary sowing of tomato seeds under the film cover and taking care of the growing season can significantly reduce labor costs and increase …
