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．
