Abstract
This thesis examined the causes of salt sensitivity and mechanisms of tolerance in chickpea (Cicer arietinum L.) using salt-sensitive (Rupali) and salt-tolerant (Genesis836) genotypes. Salt sensitivity in chickpea during the vegetative stage is determined by Na+ toxicity. The two genotypes differed in 'tissue tolerance' to Na+ - leaves of Genesis836 maintained higher photosynthesis and suffered less necrosis than those of Rupali. Differential expression of candidate genes associated with tonoplast Na+ transport might contribute to this difference in tissue tolerance. Salt sensitivity of reproductive growth was related to insufficient photo assimilate availability which limited branch growth and thus flowering/podding sites and seed growth.
