| 摘 要： | 对不同茶树品种的健叶和病叶上分离的内生细菌进行了筛选和鉴定。结果表明,茶树体内存在大量的内生细菌,各品种间内生细菌的数量为2.9×106~39.4×106cfu/(g?fw)。内生细菌的生物功能测定结果表明,菌株TL2的拮抗能力强,先接种菌株TL224h后再接种茶轮斑病菌的防病效果好;同时菌株TL2对氯氰菊酯也表现出较强的降解能力;另外菌株TL2能在茶树上内生定殖。经鉴定,菌株TL2为枯草芽孢杆菌(Bacillussubtilis)。

| 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× 106~39.4×106 cfu/(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. |
