and Seedling Growth of Brassica rapa under Nacl Stress

Abstract

2 Abstract: Abiotic stress is an important environmental problem limiting crop growth and productivity. Micronutrients have ability to overcome stress up to some extent. This study was carried out to investigate the effects of priming with micronutrients (Zn and Cu) on Brassica rapa grown under NaCl stress. Seeds were primed with 100 and 200 ppm ZnSO and CuSO and then treated with different concentrations (0 mM, 60 mM, 44 90 mM, 120 mM) of NaCl. Effect of NaCl, ZnSO and CuSO were observed on germination, seedling growth 44 separately. It was observed that germination and different seedling growth parameters viz. shoot length, root length, fresh and dry biomass were decreased under different concentrations of NaCl (without treatment of ZnSO and CuSO ). It was also observed that treatment with different doses of ZnSO and CuSO exhibited 44 44 increase in germination and seedling growth in both salinity levels as well as in non-saline conditions.
