| 中文摘要: |
| 以药用植物金银花为材料，对其根部、茎部、叶片不同部位的内生细菌进行分离纯化，对细胞特征采用革兰氏染色、芽孢染色法进行研究，结合菌落特征和生理生化特性将其内生细菌初步分为第1类型和第2类型两大类。采用稀释涂布法对金银花不同部位分别进行可培养内生细菌计数。结果表明，内生菌的总体数量分布为根部>叶片>茎部，说明内生细菌在金银花组织中的分布因部位不同而不同。基于细胞染色特征、显微观察结果和培养特性，内生菌中第1类型符合芽孢杆菌属(Bacillus)的特点，第2类型具有类芽孢杆菌属(Paenibacillus)的特征。 |
| 英文摘要: |
| Taking medicinal plant Flos Lonicerae as experimental material, endophytic bacteria of different parts of root, stem and
leaf were isolated and purified, cell features were determined by Gram dye and Spore dye methods. They were preliminary classified into two types （first type and second type） combined clony characteristic, physiological and biochemical characteristics. Microbes were counted by dilution spread method for different parts of F. lonicerae. Results indicated that distribution of endophytic bacteria total number in root was the most, leaf was second and stem was the least, it suggestted that distribution difference of endophytic bacteria in F. lonicerae was in accordance with different parts. Based on dye features, microscopic observation results and cultive characteristics, endophytic bacterial first type was accorded with genus Bacillus, and second type was accorded with characteristics of genus Paenibacillus. |
