Effect of different levels of Salinity on growth and photosynthetic pigments of Wheat Plants (Triticum aestivum L. Var. Raj- 3765).

Abstract

Plant growth is the result of many integrated and regulated physiological processes. Salinity, which is one of the major abiotic stresses, causes alterations in a wide range of physiological, biochemical and molecular processes in plants. It decreases plant growth and yield, depending on the plant species, salinity levels and ionic composition of the salts. In this study, Triticum aestivum L. var. Raj-3765 was selected as the test species. Six different levels of salinity were maintained to conduct the experiment for finding out level of tolerance of salinity by this crop plant. Salinity levels were prepared by adding different concentrations of Saline water (SW) and double distilled water (DW). The best growth of this crop plant was observed at level 2 i.e. SW: DW: 10:90.
