Abstract

Zn is essential for plant growth and physiological processes, but they become toxic at elevated levels. In this study, effects of zinc (Zn) on corn plants were studied. Different Zn concentrations(0, 0.2, 1.5 and 3 ppm) were externally applied on plant leaves. Plants’ height and leaf numbers were not affected by the application of different Zn applications. Relative water content (RWC) increased gradually with increasing Zn concentration followed by decreased at higher level of Zn application. The net photosynthesis rate (Pn) showed similar to RWC results. Chlorophyll (Chl) content increased in Zn-treated plants than Zn-untreated plants but Chl fluorescence increased only at higher Zn concentration condition. Zn application increased yield compared than control but did not differentiate among Zn treatments. Taken together, it seems that Zn at 1.5 ppm as foliar application showed better result in terms of production and physiology of corn plants.
