Plants need various micro and macronutrients for their growth and metabolism. Of these nickel (Ni) plays a role of micronutrient but causes adverse effects when present above optimum level. To combat such situations plants possess different growth regulators. Jasmonates are a class of plant growth regulators modulating various growth and physiological responses in plants. Aiming to evaluate the effect of nickel and jasmonic acid on growth and antioxidant enzymes Superoxide distmutase (SOD), Catalse (CAT), Ascorbate peroxidase (APX), Guaiacol peroxidase (GPX) and glutathione reductase (GR), seeds of Zea mays L. were sown in field after giving presowing treatment of NiSO4 · 6H2O (8 mM), jasmonic acid JA (10–6, 10–8 and 10–10 M) alone and JA (10–6, 10–8 and 10–10 M) in 1: 1 combination with NiSO4 · 6H2O (8 mM) in plant conservatory, Punjabi University, Patiala, Punjab, India. Plants of each treatment group were then subjected to spraying treatment with the respective treatment solutions at regular intervals of 22 days up to 66 days after sowing (DAS). The present findings signified reduced growth with Ni treatment but co-application of JA alleviated the effect of nickel through activity of antioxidant enzymes.
