摘　　要： 以豫麦18号小麦种子为材料,初步探索了不同压力和时间对不同处理的小麦种子发芽的影响,并对95 MPa压力、不同时间处理下发芽种子幼苗的生长情况进行测定.结果表明:在50～95 MPa压力下,直接真空包装的小麦种子均丧失发芽能力;在不同压力和时间下处理直接加水包装的小麦种子,种子发芽受到显著抑制;将水浸6 h再加水包装的小麦种子在95 MPa压力下处理4 h,能抑制小麦种子的发芽势和发芽率,但抑制强度较弱,也表明水可以有效降低高压对小麦种子的损伤.在95 MPa压力下、不同时间处理的直接加水包装的小麦种子幼苗的平均苗高和幼苗鲜重均大于对照. 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 6h 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.
