The Effect of the Electric Current Frequency on some Growth parameters in thetwo cultivated of Solanummelongena L. Plant

Abstract

The experiment was conducted in the garden at the teachers training institute at the growth season 2012.The experiment was design- -ed by Completely Randomized Block Design(CRBD). The seeds of two cultiv -ated of eggplant were taken they were: 1- Lot(Number)Melanzana was American origin and signed as No. (1). 2-Aydin Siyah was Turkish origin and signed as No. (2). Seeds were exposured for three Frequencies of electric current (1,2 and 2.5)Am for 5 min.to each frequency by using a machine that gives electric and magnetic current by means of circled wires to study the effect of these frequencies on plant growth as wall as the control .Then the treated seeds were planting on 15/4/2012 in the garden, then, they were prepared and fertilized.Some growth parameters were studied, they were (high of the plant,Leaf number and dry weight, Leaf area ,radious and number of flowers). The results showed a significant increase for the vairty 1 at the (2.,5) Am frequency compared with the vairty 2 and with all the frequencies that given the best values for the studied parameters .
