Evaluation Potential of L.triscula L. in the absorption of Zn and its effects on tissues

Abstract

The aim of our work was to illustrate absorption of Zn ion and anatomical changes induced by the metal ion in Lemnatriscula L.Plants were cultured in Hoagland medium supplemented with various zinc concentrations (1,3,5,7 and 9 mg/ml) and harvested after 3 days and the metal ion accumulation within the plants was determined. Anatomical changes in the metal treated plants were observed to access the toxic effect of the metal. Treated plants of L. Triscula L. when examined by light microscopy, exhibited alteration in leaf diameter, disintegration of epidermis and layer of cortex (aerenchyma cells) and variation in vasculature resulting from Zn ion toxicity
