The Influence of High Voltage Electric Field for Barley Seed Germination and its Mechanism

Abstract

This paper through the effect of seed germination under different voltage that it can concluded that the influence of electric field on seed growth.Experiment to select different gradient field acts on the barley seed, the results show that the appropriate voltage of the electric field and action time has obvious promoting effect to seed germination. By discussing the electric field effect on the cell membrane permeability, using a planar lipid double model, discussed that high voltage electric field makes the cell membrane barrier height change.Ion through the barrier of risk as a result of the existence of tunneling effect will be affected by the barrier height, namely transmembrane potential.Thus an effect on the permeability of cell membrane.

Improvement of wheat seed vitality by dielectric barrier discharge plasma treatment

“…Several seed improvement methods have been employed to enhance seed vigor, including chemical treatments (chemicals, fungicides, and hormones) [Zehra et al, ; Zhao and Jiang, ] and physical treatments (ultrasonic scratching, electric field treatment, magnetic treatment, ion beam scratching, etc.) [Goussous et al, ; Xu et al, ; Shi et al, ; Yao and Shen, ]. Chemical methods are usually labor‐intensive and expensive due to large amounts of chemical consumption; even worse, residual chemicals on the seed coat surface could contribute to soil pollution.…”

“…As physical methods, ultrasonic scratching and ion beam scratching could improve seed vigor, and electric and/or magnetic treatments have also been confirmed to enhance seed vigor by influencing biochemical processes such as protein and enzyme activity [Moon and Chung, ]. However, these physical methods have limitations; for example, strong ultrasonic oscillation or ion beam collision might injure seed cells, thus increasing the number of destroyed seeds, and physical methods could lead to a higher possibility of a non‐uniform treatment [Goussous et al, ; Xu et al, ; Shi et al, ; Yao and Shen, ].…”

Effect of Electrical Current Applied in Soaking Conditions on Germination of Acacia and Maize Seeds

“…A similar effect has been observed in other plant seeds such as morning glory, cotton, tomato, carrot, radish, beet and barley (Isobe et Shi et al, 2014). Although several electrical treatments improved germination capacity and growth in both types of seeds, a clear treatment-response relationship could not be made, neither for time nor for voltage.…”

“…They explained the effect in terms of changes in electrical polarization of cell membranes and the hydration of stored macromolecules. Moreover, Shi et al (2014) indicated that high voltage electric field influence transmembrane potential affecting permeability of cell membrane. Isobe et al (1999) explained the negative effect of electrical current in terms of water distribution into the seeds.…”

Outcomes of Pulsed Electric Fields and Nonthermal Plasma Treatments on Seed Germination and Protein Functions

“…[37] Barley 2-9.5 kV; exposure time (35 min) An increase in seed germination, germination index, germination potential, and vigor index was observed for 3.5-and 5-kV treatment. [38] Bitter gourd (Momordica charantia) Electric field intensity (30-100 kV/m); exposed time (20 min) Seeds treated at 30-and 50-kV/cm showed a positive effect on germination, while higher intensity treatment (100 kV/m) caused the decrease in germination. 3-V and 6-V treatment results in early seed germination, while no difference for control and 12 V. The increase in the plant heights observed for 3, 6, 9, and 12 V as 25.5, 30.5, 11.8, and 17.1%, respectively.…”
