The effect of salinity on germination , growth characters , and emergence of barley Hordeum vulgaris L. in different soil textures

Laboratory experiment in Petri dishes was conducted to study the effect of different salt concentration levels (3,6,9,12 and 15)dS/m of NaCl, and to distill water treatment as acontrol, on germination percentage of barley seeds The results showed an increase of salt concentration levels(6,9,12 and 15) dS/m causing adecrease in germination percentage (2%,3%,5%, and 8%) respectively, the length of plumule and radicle of seedling and their dry mater weight decreased too.Other two experiments in plastic pots were adapted to study the effect of the salt at the same concentration levels on growth , percentage and rate of emergence. The results showed that the growth in terms of stem, length and their dry matter weight and the percentages of emergence were decreased , as aresult of the increase of salt concentration levels at different soil textures whereas the mineral contents were increased
