Abstract

ABSTRAC r.. Four eggplant cultivars nam ely Black Beauty (BB), Long Purple (LP) , Florida Mark et (FM) , Egyptian White (EW) were used to test the effect of drought on morphological and physiological trait s under field conditions during summ er and spring seasons in 1991·92, Drought stre ss reduced plant height , leaf area , number of leaves , number of branche s, stem diameter, leaf dr y weight and root dr y weight during both seasons. Significant differences were observed among differ ent eggplant cult ivars in their response to seasonal variation causing substantial effect on plant growth. High temp erature associated with drou ght stress during summer caused more plant injuri es than spring season . Florida Market (FM) cultivar showed more toler ance to stress than other eggplant cultivars in most morphological and physiological traits. It appears from the result s that an improvement in eggplant cultivarscould be made throu gh breeding program .
