Zinc (Zn) is an important microelement in increasing the yield and quality of plant production. In addition, zinc deficiency in the seed can be a nutritional problem and therefore a serious problem in human health. In order to overcome the problem Zn application method as priming of seeds in dilute Zn solutions prior to sowing recently came to forward because of having many advantages. No studies under controlled conditions could be met in literature regarding on this subject. This study aimed to find out the effect of plants obtained from seeds of corn (Zea mays L.) which have been soaked in 5 mM ZnSO4 at different time periods (0 min, 1 min, 10 min, 30 min and 60 min) grown in with Zn (Zn: 1 μM ZnSO4) and without Zn (Zn: 0 μM ZnSO4) conditions for approximately 12 days (1. harvest) and 20 days (II. harvest) on the severity of Zn deficiency symptoms, root and shoot dry matter yield, as well as the concentration of Zn in shoot and root in a hydroponic experiment. In this experiment, increases in dry weight and Zn concentration both in shoots and roots of 12 and 20 days harvested plants which of seeds were soaked in Zn solution at different time periods have been seen in comparison with the control plants. Mentioned increases with respect to dry matter yield increased parallel to the soaking time of seeds in solution especially at II. harvest. In contrast to dry matter yield, Zn concentration was higher in plants obtained at I. harvest while it decreased in plants obtained at II. harvest. Zinc concentrations of plants were found to be higher at I. harvest than those of the ones obtained at II. harvest particularly under the conditions of without Zn application from the solution. As a result, it has been determined that the application method of soaking of the seeds in Zn solution at a certain time has a significant effect on the severity of symptoms of Zn deficiency, dry matter yield and Zn concentration.
