A comparative study of heavy metal accumulation and antioxidant responses in Jatropha curcas L

Abstract

Jatropha curcas L. commonly known as physic nut or purging nut, is a drought resistant shrub belonging to the family Euphorbiaceae, was analyzed for its accumulation capacity of heavy metals such as lead (Pb), cadmium (Cd) and chromium (Cr). Bioassay was conducted by raising the plant by vegetative propagating the stem cutting in varying concentration of respective heavy metals. The metal concentration in the bioparts of experimental plant revealed that the treated plants accumulated enormous quantity of lead, cadmium and chromium as compared to control plant. The effect of heavy metal stress on antioxidant activity in of J. curcas was investigated. The activity of enzymatic antioxidant such as superoxide dismutase (

Physio-anatomical modifications and element allocation pattern in Alternanthera tenella Colla. associated with phytoextraction of chromium

“…Alternanthera tenella Colla (Amaranthaceae) is a fast-growing, invasive alien herb widely found in India, especially in polluted areas such as industrial zones. A. tenella is a facultative metallophyte and has already been proven as a bioaccumulator of Cd under controlled micro-conditions (Rodrigues et al 2017) and also showed responses to various HM stress (Chinmayee et al 2014). However, additional studies with this species can also verify its potential use as a bioindicator and phytoremediator in areas contaminated by these heavy metals.…”

“…El estudio reveló disminución de actividad de CAT y PAL en L. hexandra en la mayor dosis de HTP (90 g kg -1 ), similar efecto para CAT fue reportado porAchuba (2014) en Vigna unguiculata y Zea mays expuesta a queroseno, yRusin et al (2018) en Triticum aestivum L expuestas a aceite de motor y diésel. La respuesta en PAL fue similar a lo reportado porChinmayee et al (2014) en Jatropha curcas L. y JaEczak-Pieni}ek et al…”
