Biological effect of endophyfic bacteria in Fortunate Bamboo
富贵竹内生细菌群落的生物效应研究

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.
