Sulphate salinity, in general, was found more detrimental than chlorid
e salinity in all the four cultivars, 40048 Morocco '88', Sunbar, Mari
s mink and 6-Row of barley (Hordcum vulgare L.) grown in hydroponic cu
ltures containing iso-osmotic chloride-, predominantly chloride- and s
ulphate-, and sulphate- salinity. Amongst the cultivars, 6-Row appeare
d to be more salt tolerant and Maris mink and Sunbar comparatively sal
t sensitive in respect of shoot/root length and their ratio, photosynt
hesis, transpiration, stomatal conductance to water vapour and sub- st
omatal CO2 concentration (in 2nd leaf). Even interaction effects of cu
ltivar versus treatment were prominent in cultivar 6-Row and chloride
alone in the above mentioned parameters, thereby, indicating the resis
tance of 6-Row under chloride salinity as well.
