Soil salinity effects on the process of grain filling in barley (Hordeum vulgare L.) varieties

Experiments with four barley varieties under non-saline soil conditions have shown that the reduction in grain yield due to soil salinity is a result of decrease in 100 grain weight and number of mature/fertile grains per plant. The leaf water potential decreased under saline conditions and the more tolerant varieties maintained a higher leaf water potential. A lower accumulation of photosynthates in the grains under saline conditions during the 10th to 20th day after flowering ultimately reduces the grain yield.
