Several environmental factors adversely affect plant growth, development and yield performance of crop. More than 900 million hectares of land world-wide, approx. 20 % of the total agricultural land, are affected by salinity Osmotic stress induced by soil salinity affects plant growth and development. Salinity alters general metabolic processes and enzymatic activities, causing increased production of reactive oxygen species. In some plants increased resistance to a biotic stresses has been achieved by exogenous application of various organic solutes. This approach significantly contributes...
