Ushbu maqolada Sirdaryo viloyatida yetishtirilgan o‘simlik (Cannabis sativa L) va tuproq na’munalarida og‘ir metallar (Hg, Pb, Cr, Sn, Ni, Cu, Fe, Mn, Zn) miqdorini o‘rganish natijalari ko‘rib chiqildi. O‘simliklarni himoya qilishning antioksidant tizimining (fenollar va flavonoidlar) javobi ham o‘ziga xos bo‘lib, antioksidant miqdorining oshishi va pasayishi ham kuzatiladi, bu o‘simliklarning ifloslantiruvchi moddalar ta'siriga turli xil chidamliligi bilan bog‘liqdir. Ba'zi hollarda og‘ir metallar tarkibi, fenollar va flavonoidlar darajasi o‘rtasida korrelyatsiya aniqlandi, bu o‘simliklarning biokimyoviy stressininпg sababini ko‘rsatadi.

В этой статье расмотриваются результаты исследования содержания тяжелых металлов (Hg, Pb, Cr, Sn, Ni, Cu, Fe, Mn, Zn) в растительных (CannabissativaL) и почвенных пробах, выращенных в условиях засоленных почв Сырдарьинской области. Ответная реакция антиоксидантной системы защиты растений (фенолы и флавоноиды) была специфичной, наблюдалось как повышение, так и снижение содержания антиоксидантов, что обусловлено различной устойчивостью растений на действие поллютантов. В ряде случаев обнаружены корреляции между содержанием тяжелых металлов и уровнем фенолов и флавоноидов, что указывает на причину биохимического стресса растений.

This article discusses the results of a study of the content of heavy metals (Hg, Pb, Cr, Sn, Ni, Cu, Fe, Mn, Zn) in plant (CannabissativaL) and soil samples made in saline soils of Syrdarya region. The reaction of the antioxidant defense system of plants (phenols and flavonoids) was also specific, both an increase and a decrease in the antioxidant status were observed, which is due to the different resistance of plants to the action of pollutants. In some cases, correlations were found between the content of heavy metals and the level of phenols and flavonoids, which indicates the cause of the biochemical stress of plants.
