In order to know the effect of drought on the root of barley seedling,barley seedlings were grown in pots,in which the soil water content was maintained at 85%,55%,45%and 35% of field capacity(FC),respectively.Some conventional morphological and absorption capacity indexes in four different drought resistant barley cultivars were investigated.The results showed that the longest seminal root,the number of tips,tissue water content of the same cultivars are decreased with the decreasing of soil water centent,...
