Abstrak
Ushbu maqolada sun’iy kolmatajlangan tuproqlarida o‘stirilayotgan shaftoli, bodom va pista daraxtlarining kimyoviy elementlarni o‘zlashtirish xususiyatlari biologik singdirish koeffitsiyenti (BSK) yordamida baholandi. Elementlarning makro, mikro, ultramikro, lantanoid va toksik guruhlari bo‘yicha litosfera klarki hamda, tuproqdagi konsentratsiya bilan taqqosiy tahlil qilindi. Tadqiqot natijalari shuni ko‘rsatdiki, bodom Ca, Mn va As ni nisbatan yuqori darajada akkumulatsiya qiladi, pista esa Zn, Se va Hg bo‘yicha yuqoriroq BSK ko‘rsatkichlariga ega. Shaftoli esa K va Ca bo‘yicha barqaror o‘zlashtirishga ega bo‘lib, mikroelementlar bo‘yicha konservativ fiziologik xususiyat namoyon etadi. Tahlillar o‘simliklarning biogeokimyoviy moslashuvlari, tuproqning kolmatajlanish darajasi shuningdek, elementlarning migratsiya shakllariga bog‘liq ekanini ko‘rsatdi.
