Biogeochemistry of Plants Allium Karataviense Regel, Fritillaria Sewerzowii Regel in Mountain Brown Soils of Uzbekistan

In the article, the amount of elements and biogeochemical properties of the surface layer of mountain brown soils formed at various levels and in the organs (root, leaf, bulb) of medicinal black onion (Allium karataviense Regel), Severtsov's onion (Fritillaria sewerzowii Regel) were studied. It has been proven that Sb, and Cs are less than lithospheric clay, and Sc, Cr, and Co, on the contrary, are more than lithospheric clay. A high accumulation of cyclic and scattered trace elements was observed in the root of black onion (Allium karataviense Regel). In mountain brown soils, the order of Anzur onion root and onion bulb absorption decreases in the form of Co>Sc>Cs>Sb>Cr. This indicator was Co>Cs>Sb>Sc>Cr in small numbers on the leaf. It was found that Z/1 - O/2 Sb-1.13-1.54, Cs-7.42-7.04 mg/kg in cross-sections of mountain brown soils is less than lithospheric soil. Microelements such as Sc, Cr, and Co, on the contrary, it was observed that the abundance of lithospheric clay is Cr-61.3-67.2, Co-15.0-15.6, Sc-11.4-12.8 mg/kg. The amounts of microelements in the organs of Allium karataviense Regel and Fritillaria sewerzowii Regel plants are Cr 2.31-9.9 mg/kg, Co-0.073-0.057 mg/kg, Sb-0.0090-0.089 mg/kg, Sc-0.035 -0.40 mg/kg, Cs-0.024-0.24 mg/kg. These elements are also included in the plow layers of mountain brown soils: Cr-61.3-67.2 mg/kg, Co-15.0-15.6 mg/kg, Sb-1.3-1.54 mg/kg, Sc-11.4-11.8 mg/kg, Cs-7.42-7.4 found to be in mg/kg amounts.
