| 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 6 4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 2 2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 2 5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 s how that there are many endophytic bacte ria with different biological effects in Fortunate Bamboo.64 strains of endophyt ic bacteria are isolated from the sympto m free leaves and stems of 4 varieties o f Fortunate Bamboo.There are 22 strains having pathogenicity when tested by the methods of tobacco-senstive-reaction and half-leave-inoculatio n.Being tested in plate,16 strains have anti-fung al effect on one plant pathogen fungi(PPF),5 stra ins have anti-fungal effect on 2 PPF and 4 strains have anti-fungal eff ect on 3 PPF.The total number of anti-fu ngal stra ins is 25. 16 strains can stimulate the g rowth of rice or green bean.Mixed stimul ating-growth strains also can s timu late Fortunate Bamboo to produce roots. |
