| 摘 要： | 选取高低两个LET点(40和60keV/m),剂量点分别为50,100,200,400,600Gy进行辐照处理,研究了生防菌的存活率与突变率的关系,抑菌谱以及活性等。结果表明,在高LET条件下,低剂量辐照就可以得到较多的突变体,并且BJ1有较高的存活率和突变谱,有利于筛选优良的正突变体。因此高LET较低LET有更为明显的辐射诱变效应。 |

| Abstract: | To explore the effects of different linear energy transfer(LET)of 12C6+ ion Beam irradiation on BJ1, survivals and biocontrol effects were cultured and treated with LET=40 and 60 ke V/mm at the doses of 50, 100, 200, 400 and 600 Gy, respectively. The results showed more mutations and biocontrol charts and higher survivals were obtained with high LET(60 ke V/mm) irradiations at lower dose, which was useful to screen good positive mutations. Based on the results above, it could be concluded that the condition... |
