The elevated concentration of salts in soils impact plant growth and development by disturbing the capacity of roots to extract water and high levels of salts within the plant supress the physiological and biochemical processes such as nutrient uptake and assimilation. Salinity induced wheat leaves were analysed for various physiological parameters viz. relative water content, leaf membrane injury, osmotic potential and chlorophyll fluorescence at five days after treatment of spermine at 1.0 mM concentration. Spermine treatment showed higher relative water content and improved efficiency of photosystem II (Fv/Fm) indicating increase water retention capacity in control and salt stressed condition. Further, spermine treatment alleviated the salinity induced leaf membrane injury with marked decrease in ion leakage and played protective role.
