Abstract:
Taking‘Jinchun No.2’cucumber seed as materials，the effect of different strength high voltage electric field（100，200，300，400 kV/M）and drought stress simulated by PEG6000 on influnce of cucumber seeds germination were studied.The results showed that germination rate，fresh weight，germination index and vigor index of cucumber seeds in drought stress were improved by using high voltage electric field，activity of SOD，POD and CAT of cucumber seeds during germination were significantly higher than control，and MDA was decreased.The experiment deduced that electrostatic field which could improve enzyme activity was played an important role in seed germination under drought stress.
