This study was performed to study the Effects of in vitro water stress on some growth characters of two rice( Amber33 and Mishkhab2) cultivars. A mature seeds of two rice cultivars( Amber 33 and Mishkhab2) were cultured on Murashige and Skoog medium supplemented with with 3 different Polyethylene glycol 6000 (PEG) concentrations (0, 1,2and 3%) for 14 and 21 days to study the effect of water stress on seedling length , root length , fresh weight and dry weight . Results showed that addition of PEG resulted in decreasing means of all studied characters with the increasing of PEG concentration in MS medium. A significant difference recorded between cultivars; Amber33 produced the highest seedling length, fresh and dry weight, root number and root length compared with Mishkhab2.
