| Abstract | ||||
| A pot experiment was carried out to study how pretreatments in aspirin (0.3 &0.6m M) or kinetin (50&100 ppm) counteract the harmful effects of drought stress (by irrigation with 50% of water field capacity) on lettuce plant during vegetative stage. The present results revealed that drought stress significantly decreased shoot length, No. of leaves, No. of nodes, fresh & dry weights, chlorophyll a, chlorophyll b, chlorophyll a/b, carotenoids and total pigments, in lettuce plants, after 25 days from sowing. These deleterious effects that caused by drought mitigated; either partially by soaking lettuce seeds in 0.3 mM aspirin or 50 ppm kinetin or completely by soaking lettuce seeds in 0.6 mM aspirin or 100 ppm kinetin. In general, this investigation confirms the ability of aspirin and kinetin in improving growth of lettuce as well as nullifying the harmful effects of water shortage in irrigation. | ||||
