Abstract
In this work, the impact of "Dielectric Barrier Discharge (DBD) Plasma jet" (5.47 watt) on germination and activation of Squash seeds (Cucurbita pepo L.) was studied at different times. The seeds were divided into (soaked seeds and dry seeds). After the process of exposing the seeds, measurements have been taken for three characteristics of germination (root length, shoot length, number of leaves). The results show that exposing the plasma jet on the seeds soaked with water is better than dry seeds. The results of exposure to the seeds are shown at the length of viability at the exposure time of (5 min), outperforming the control by 15.80 % while there was no effect at (0.5 min), as it turned out that there is a during various exposure periods (0.5, 1, 3, 5 min) along the shoot and the number of leaves compared to the control. This confirms that the discharge of the plasma dielectric barrier contributes to stimulating the seeds and increasing their germination rate.
