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, at Ministry of Agriculture, Beit-Lahya city, Gaza Strip, Palestine. The experiments aimed to study the effect of soil lead pollution and iron foliar application on spinach plants. Measurements of the lead effects on spinach plants revealed: (a) Growth characters such as root length, shoot height, total leaves area, fresh and dry weights of root, shoot and whole plant were decreased with increasing Pb soil addition. (b) Plant pigments such as chlorophyll a, chlorophyll b and total carotenoids were decreased with the increasing of Pb concentration in the soil. Iron foliar application on spinach plants revealed: (a) Growth characters and plant pigments of plant were increasing with increased concentration of alone iron. (b) Toxicity of Pb on growth characters and its effect on elemental transport and accumulation were reduced when it combined with Fe foliar application.
