凡是能引起生物体遗传物质发生突然或根本的改变,使其基因突变或染色体畸变达到自然水平以上的物质,统称为诱变剂。当各种诱变剂被人为地强加于地球环境中之后,生物基因的情报系统由于诱变剂的作用受到损伤而发生紊乱,不能正确地传递遗传信息,具体地说就是发生了突变。那么这类诱变剂则被认为是环境诱变剂。未经人工处理而发生的突变称为自发突变;经过人工处理而发生的突变称为诱发突变。

以灰葡萄孢BC4为出发菌株,通过紫外线和化学诱变剂诱变分生孢子,共获得50个菌株。
The main results are as follows:(1) Treated by ultraviolet ray and chemical mutagen, 50 isolates were obtained from isolate BC4's conidial suspension.
方法:用化学诱变剂对菌种进行诱变育种,筛选得到的菌株通过摇瓶试验考察其产抗能力与传代稳定性。
Methods: To mutate breeding for strain by chemical mutagen. Its producing resistant ability and propagating stability of strain obtained by screening was observed by shaking flask test.
