摘　　要：本文用玉米干种子作为实验材料,设打印纸覆盖、铝箔覆盖和不覆盖3个处理,研究了在低能离子注入种子的过程中,温度对种子发芽率的影响。研究结果表明3个处理中不能传递热量的打印纸覆盖的种子发芽率最高,不覆盖的种子的发芽率其次,而可以传递热量的铝箔覆盖的种子发芽率最低。温度能够显著影响注入后种子的发芽,靶室内的高温总体上降低了种子的生活力。文中对离子注入时的温度效应做了校正,并给出了校正后的种子发芽曲线。The temperature effects of low-energy ion beam implantation on the seed germination were studied. Maize dry seeds were covered with copy paper, aluminum foil and without cover, respectively. Results showed that the germination rate of the seeds covered with paper which was the bad heat transmitter was the highest among three treatments, while that covered with aluminum foil which can transmit heat energy well was the least. The germination rate of the seeds covered with nothing was the second. Temperature affected seeds germination markedly. Generally the temperature of the target room inhibited the seeds＇ germination. After minus the effects of the temperature in the target room, the germination rates of the seeds were modified in this paper. The modified germination rate curve was also provided.
