富贵竹内生细菌群落的生物效应研究

Biological effect of endophyfic bacteria in Fortunate Bamboo

  • 摘要: 试验研究结果表明富贵竹中广泛存在具有多种生物效应的内生细菌群落。从4个品种富贵竹茎叶中分离出64个内生细菌,以烟草过敏性反应和半叶接种法测定其内生细菌中有22个菌株具有潜在致病性;采用抑菌圈法测定其内生细菌中有25个菌株对6个病原真菌具不同拮抗作用,其中分别有16个、5个、4个菌株对1种、2种和3种病原真菌有拮抗作用。有16个菌株可刺激水稻或绿豆生长,具有刺激生长作用的混合菌株还可促进富贵竹生根。

     

    Abstract: The experiments show that there are man y endophytic bacteria with diferent biological effects in Fortunate Bamboo.64 strains of endophytic bacteria are isolated from the symptom free leaves and stems of 4 varieties of Fortunate Bamboo.There are 22 strains having pathogenicity when tested by the methods of tobacco-senstive-reaction and half-leave-inoculation.Being tested in plate,16 strains have anti-fungal efect on one plant pathogen fungi(PPF),5 strains have anti-fungal effeCt on 2 PPF and 4 strains have anti-fungal efect on 3 PPF.The total number of anti-fungal strains is 25.16 strains can stimulate the growth of rice or green bean.Mixed stimulating-growth strains also can stimulate Fortunate Bamboo tO produce roots.
