Salinity is one of the important stresses resulting in the reduction of growth and yield of different crops including wheat. In
saline soils the concentration of Na+
and Clis higher accompanied with the decreased K+
: Na+
ratio thus severely affecting
the growth and yield of crops. The effect of salinity on the growth and yield of wheat is well documented, whereas there is
very little information about salinity tolerance and grain quality of wheat. Present study was conducted to assess the effect of
salinity on yield components, ionic relations and grain quality and to understand the relationship among these parameters. A
pot experiment was conducted using wheat genotype Pasban-90. There were two treatments i.e. non-saline (0.33 dS m-1
) and
saline (15 dS m-1
) with five replications. Salinity resulted in a significant reduction of the grain protein, fat and fiber contents.
Similarly yield components were significantly reduced. Maximum reduction was noted in case of number of tillers plant-1
,
followed by grain weight plant-1
. High Na+
and low K+
, P concentration and K+
: Na+
ratio was observed in the shoot, root and
grain. This disturbed ionic composition seems to be apparent cause of yield reduction and deterioration of wheat quality
under salinity.
