Abstract

Abstract: The screening and identification of endophytic bacteria from the healthy and diseased leaves of various tea cultivar plants were conducted. Results showed that the endophytic bacteria were accounted in 2.9×10⁶~39.4×10⁶βcfu/(g•fw) in tea cultivars plants. The TL2 stain showed strongly antagonistic activity against leaf fungal pathogens of tea-plant. It showed a good protecting effect when inoculated the TL2 strain bacteria firstly than inoculated the tea grey blight pathogen(Pestallozzia theae) later, Besides, it showed a strong degrative activity to cypermethrin. The TL2 bacteria strain could colonize within tea plant. According to the results of identification, the TL2 bacteria strain was identified as bacillas subtilis.

Key words: Tea-plant, Endophytic Bacteria, Antifungal, Pesticide Degrading, Bacillus subtilis
