Outline
Using the wheat seed of Yumai No. 18 as material, the effect of high pressure on seed germination and seedling growth of wheat was preliminary studied, and seedling growth of wheat that treated under 95 MPa pressure in various time was investigated. Results showed that, in 50~95 MPa pressure, all vacuum-packed seeds could not germinate; the germination of seeds that packed in water was inhibited significantly; the germination power and germination rate of seeds soaked for 6 h and packed in water were slightly inhibited. These indicated that water could alleviate the harm of high pressure to wheat seed. The average seedling height and seedling fresh weight of wheat seeds treated by 95 MPa pressure in various time both exceed CK.
