Soil Salinity Essay
concentration, malondialdehyde and hydrogen perocide and activity of salinity stress peroxidase (POD) and catalase (CAT) in eggplant plants under salinity stress.
Exogenously applied No increased plant growth significantly both in saline and non-saline conditions. As a consequence of salinity stress, lipid peroxidation, measured in terms of malondialdehyde (MDA) concentration and membrane permeability was decreased by NO. H2O2 concentration was increased by increasing levels of NO. NO also strongly inhibited Na+ and Cl_ accumulation, but stimulated N, P, K, Ca and Mg concentrations of salt stressed canola plants.
The present investigation suggested that NO, a stress signal could trigger the activation of antioxidants in the plants to alleviate the oxidative damage leading to improvements in physiological attributes for the plant growth under salinity.
Key words: Canola, inorganic nutrients, Nitrose oxide, proline, salinity, Zea mays
Vegetable oils are, and have been an important component of the human diet for a long time. Nowadays, the four major vegetable-oil producing crops (oil-palm, soybean, rapeseed and sunflower, respectively) cover about 270 million hectares, with a production of 170 million tons, and accounting for approximately 75% of the world total production (FAO, 2013). In general, Egypt 's production of vegetable oils, covers only a small portion of its current demand. According to Hassan and Shafique (2011), Egypt’s self-sufficiency…
