摘要：
Lentil is known to be sensitive or moderately tolerant to salt stress. Screening lentil genotypes for salt tolerance is of practical importance, therefore, a pot experiment on lentil comparing six genotypes (Masoor 93, Mansehra 89, NL 53, NL 40-62, NL 71-2, NL 73) and three salinity levels (0, 4, 8 dS m(-)1 was conducted in greenhouse at NARC, Islamabad. Salt tolerance was assessed in terms of dry shoot biomass, plant Na and K concentration and Na/K ratio of lentil plant. The crop was found sensitive even at low level of salinity. A linear decrease in shoot biomass was observed in all genotypes. On an average, shoot biomass decreased by 54% and 86% at 4 and 8 dS m(-1) salinity levels, respectively. Concentration of K decreased and that of Na increased in plant tissues of all genotypes with increasing salt level. Differential accumulation of Na, K and Na/K ratio in lentil genotypes was closely associated with their salt tolerance. There was wide variability in Na/K ratio of lentil genotypes. Minimum Na/K ratio of 1.77 found in Masoor 93 and 1.81 in Mansehra 89 showing their more tolerance to salinity than other genotypes. Maximum Na/K ratio was found in NL 40-62 (2.79) followed by NL 71-2 (2.69) indicating their more sensitivity towards salt stress.
