摘要
以低能N+注入凤仙花(Impatiens balsaminaL)种子后获得了高茎、矮茎2个变异品系.对其进行过氧化物同工酶(POD)检测的结果表明,2个变异品系叶片的POD分子大小、表达强度和条带数目与对照相比都发生了一定变化.随机扩增多态性DNA(random amplified polymorphic DNA,RAPD)分析结果也表明变异品系DNA链的脱氧核苷酸序列发生了变异,从25个随机引物中筛选出了9个具有多态性.实验证明适当剂量的低能N+注入能够在基因水平引起凤仙花的变异,为花卉产业的发展提供了一种遗传育种手段.
After being treated with low energy N＋ implantation, the two kinds of mutated Impatiens balsamina, one is higher and another is lower, are obtained. By using isozymic method it indicates the peroxidase variance in the molecular size, expression and the number of bands between the mutations and normal kind. By using random primers, Genetic constitutions of mutations and normal kind are analyzed by RAPD（random amplified polymorphic DNA） technique, 9 primers have polymorphic fragments between higher and normal plants, 3 primers have polymorphic fragments between lower and normal plants. This result suggests that the injection of nitrogen ions can cause the mutation of plant and be used in flower industry.
