摘　　要：采用聚丙烯酰胺凝胶电泳技术,研究了培养4 d的小麦种子(周16、豫麦49号)离子注入前后,根和幼叶中POD同工酶的变化。结果表明:离子注入可引起不同的小麦品种、同一品种的不同器官POD同工酶的酶带与酶活性的不同变化。对周16来讲,离子注入对根的影响比较显著;对于豫麦49号而言,离子注入对根和幼叶都有影响,但对幼叶的影响稍大一些。The wheat seeds cultured for 4 days were treated by N^＋ beam irradiation and the POD variation in the leaves and roots of different wheat varieties（ Zhou 16 and Yumai 49） was detected by PAGE method. The results showed as follows： the ion implantation caused the change of enzyme band and activity in the different cultivars as well as in the different organs; The more changes appeared in the roots of Zhou 16, while the changes occurred both in the roots and in the leaves of Yumai 49.
