Metal Uptake, Oxidative Metabolism, And Mycorrhization In Pigeonpeaand Pea Under Arsenic And Cadmium Stress, Neera Garg, Priyanka Singla, Purnima Bhandari
Turkish Journal of Agriculture and Forestry
Presence of arsenic (As) and cadmium (Cd) at elevated levels in the soils is threatening agricultural productivity. Arbuscular mycorrhizae (AM) enhance plant resistance to metal(loid)s by sequestering them into roots, thus restricting their translocation into leaves. The present study evaluated differential responses of AM-colonized Cajanus cajan and Pisum sativum plants to As and Cd uptake and oxidative metabolism under As and Cd stress (0, 30, and 60 mg kg-1). Arsenic uptake was significantly higher than Cd uptake, which caused greater growth inhibitions and induced oxidative stress. Pea was more sensitive, with higher toxicity symptoms in roots than leaves. Mycorrhizae were …
