摘要
取百合(Liliumbrownvar.viridulumBaker)鳞片和半夏(Pinelliaternata(TH)Bri-et.var.vulgarisEngl.)块茎作外植体,基本培养基MS,附加成份有6-BA与KT和NAA.经试验后进行批量生产时,发现严重的细菌污染,经微生物学鉴定,污染细菌系土壤杆菌属(Agrobacterium)的一个种,采用混合配制的灭菌剂D_2(升汞加次氯酸纳)防治污染菌,其防除效果可使80%以上的外植体正常生长而无污染。
Explants were taken from scale of Liliuin brownii var.viridulum and tubercle of Pinellua ternata var.vulgaris, and cultured on the MS medium added 6-BA,KT and NAA. Lots of plantlets were produced in the experiment,but serious contamination of bacteria occured. The bac-terium was a species of Agrobacterium by microbiological identification. In the experiment,the con-tamination could be controlled with the mixed disinfectant D_2(sodium hytochlorite,mercur chlo-ride,etc.),which could make 80% plantlets growing normally.
