Abstract

Increasing concentrations o f lead (0, 100, 200, 400 ve 800 mg L-1) on germination o f some important summer vegetables (tomato, pepper, eggplant, cucumber, watermelon, okra, maize, squash, melon ve bean) was investigated. Effects o f lead on G-max (germination rate), G-ind (germination index), T-mean (mean germination time), T50 (germination half time) G75-25 and G90-10 uniformity indices o f summer vegetable seeds was different according to species. Effect o f lead was negatively on germination rate in tomato, pepper, bean and maize at 100 mg L-1 Pb; in okra at 400 mg L-1 Pb; in cucumber and melon at 800 mg L-1 Pb. Germination index decresed in tomato, pepper, eggplant, cucumber, squash, bean and maize at 100 mg L-1 Pb; in watermelon and okra at 400 mg L-1 Pb; in melon at 800 mg L-1 Pb. Germination half time delayed in pepper, eggplant, squash, bean and maize at 100 mg L-1 Pb; in watermelon at 400 mg L-1 Pb; in tomato, cucumber and melon at 800 mg L-1 Pb. Mean germination time limited in pepper, eggplant, squash, melon, bean and maize at 100 mg L-1 Pb; in watermelon at 200 mg L-1 Pb; in cucumber and okra 400 mg L-1 Pb; in tomato at 800 mg L-1 Pb. According to this data, melon, cucumber, tomato, okra and watermelon was more tolerant against to lead.
