Abstract

Salinity is one of the abiotic stresses adversely affecting plant growth and productivity Salt tolerance of plants requires knowledge of the physiological mechanisms and recognition of genes which affect plant tolerance at different plant growth stages Recently the researchers try to improve plant tolerance to salt stress via biofertilizers treatments such as arbuscular mycorrhizal AM fungi AM fungi colonize plant root system and improve plant growth by various ways This chapter focuses on the mechanisms of the AM fungi which improve salt tolerance of host plants These mechanisms include the improved nutrient uptake N P Ca and Mg maintenance of the K+/Na+ ratio biochemical changes accumulation of sugar proline betaines and antioxidant enzymes and physiological changes water status relative permeability chlorophyll concentration and abscisic acid accumulation
