Impact of soil lead pollution and iron foliar application on Spinacea oleracea (L.)

The experiments were conducted on spinach plants, Spinacea oleracea L. var. balady, atMinistry of Agriculture, Beit-Lahya city, Gaza Strip, Palestine. The experiments aimed to study theeffect of soil lead pollution and iron foliar application on spinach plants. Measurements of the leadeffects on spinach plants revealed: (a) Growth characters such as root length, shoot height, totalleaves area, fresh and dry weights of root, shoot and whole plant were decreased with increasing Pbsoil addition. (b) Plant pigments such as chlorophyll a, chlorophyll b and total carotenoids weredecreased with the increasing of Pb concentration in the soil. Iron foliar application on spinach plantsrevealed: (a) Growth characters and plant pigments of plant were increasing with increasedconcentration of alone iron. (b) Toxicity of Pb on growth characters and its effect on elementaltransport and accumulation were reduced when it combined with Fe foliar application.
