Effect of High Voltage Electrostatic Field(HVEF) on the Physiological Indexes of Cucumber Seed during Germination Period

Treating cucumber seeds in 20 kV/cm of high voltage electrostatic field(HVEF) with different time of 20 s(second),30 s and 40 s.The result showed that every physiological indexes of the group with 20 s were obviously prior to comparison groups.With the time of treatment increasing,the positive effect of HVEF on cucumber seed is weakened,even restrained.
