Chromium toxicity in Moringa oleifera Lam.

This study investigated the toxic effects of different Cr concentrations (Control, 5, 25 and 50 mg/L) on hydroponically cultivated M. oleifera seedlings. At the end of the application, certain biochemical variations and changes in Cr and nutrient content (K, Zn, Ca, Cu, Fe, Mg and Mn) of the plant roots and shoots were determined. M. oleifera seedlings accumulated high Cr concentrations in roots and shoots. As a result, Cr led to nutrient deficiency by affecting the intake and transportation of the necessary macro and micro elements. Increase in phenolic compound content and non-protein SH groups may indicate that they played a role in Cr toxicity. Furthermore, the increases in H2O2 and MDA levels clearly demonstrated that Cr toxicity induced oxidative stress in M. oleifera cells.

辣木中的铬毒性。

这项研究调查了不同浓度的铬(对照,5、25和50 mg / L)对水培栽培的油茶分枝幼苗的毒害作用。在申请结束时,确定了植物根部和枝条的某些生化变化以及Cr和养分含量(K,Zn,Ca,Cu,Fe,Mg和Mn)的变化。油橄榄幼苗在根和芽中积累了高浓度的Cr。结果,铬通过影响必需的宏观和微观元素的摄入和运输而导致营养缺乏。酚类化合物含量和非蛋白质SH基团的增加可能表明它们在Cr毒性中起作用。此外,H2O2和MDA含量的增加清楚地表明Cr毒性诱导了油橄榄分枝杆菌细胞的氧化应激。
