摘　　要：用He-Ne激光处理贮存五年的油松陈种子 ,用无离子水浸种 30h后析出液的电导率比CK组低 38% ,其发芽率、活力指数最高可达CK组的 14 6 %和 16 9%。试验结果表明 ,适量的激光处理对油松陈种子的老化有修复效应。The Chinese pine seeds stored for five years was processed by He-Ne Laser. The Leachate electrical conductivity was lower 38% than CK group after the pine seeds soaked in deionized water for 30h, the germination rate and vitality index of the Chinese pine seeds could be 146% and 169% compared with CK group. The results showed that the ageing of Chinese pine seeds can be repaired by proper laser process.
