300 and 400 mM NaCl. The shoot and root respiration of two barley cultivars
(Hordeum vulgare L. variety Afzal and variety EMB82-12) were determined
in various concentrations of NaCl. Chlorophyll a,b and total chlorophyll
content were significantly decreased, but carotenoids content increased
under salinity. Decrease of chlorophyll content in EMB82-12 was higher
than Afzal, but carotenoids content in Afzal variety was higher than EMB82-12.
Relative Water Content (RWC) was used to indicate the degree of stress.
Oxygen uptake declined in shoot and root with increasing NaCl concentrations.
Decrease of oxygen uptake in shoot and root of EMB82-12 variety was higher
than Afzal variety. RWC decreased with increasing NaCl concentrations.
Lowering of RWC reduced growth and increased shoot/root ratio. Decrease
of water content in EMB82-12 plants was higher than Afzal plants. Shoot/root
ratio in EMB82-12 variety was higher than Afzal.]]>Alutoin, S., J. Boberg, M. Nystrom and M. Tedengren,2001Porites lutea.]]>52289299Brugnoli, E. and O. Bjorkman,1992187335345Delfine, S., A.
