【摘要】：【目的】了解不同品种酿酒葡萄根围、叶围细菌群落结构。【方法】以不同品种酿酒葡萄根围、叶围样品为分析材料,采用末端限制性片段长度多态性(T-RFLP)技术研究根围、叶围细菌群落结构,并对细菌群落多样性进行分析。【结果】不同品种葡萄根围微生物优势菌群为变形菌门,不同品种葡萄叶围微生物优势菌群为放线菌目。根围Simpson指数大小顺序为白福尔琼瑶浆白诗南赛美蓉白玉霓米勒长相思,Shannon指数与Simpson指数基本保持一致。叶围Simpson指数最大的为白诗南,最小的为米勒,与Shannon指数基本吻合。【结论】葡萄细菌群落结构综合多样性指数和品种以及定殖部位密切相关。
[Abstract]:[objective] to understand the bacterial community structure of root circumference and leaf circumference of different varieties of wine grape. [methods] the samples of root circumference and leaf circumference of different varieties of wine grape were used as analysis materials. End restriction fragment length polymorphism (T-RFLP) was used to study the bacterial community structure of root circumference and leaf circumference, and the diversity of bacterial community was analyzed. [results] the dominant microbial community in root circumference of different grape varieties was Proteus. The dominant microflora in leaf environs of different grape varieties was actinomycetes. The order of Simpson index of root circumference is Bai Fu er Qiong Yao pulp Bai Shi Nan Mei Bai Yu Ni Hans Muller, and Shannon index and Simpson index are basically the same. The leaf circumference Simpson index was the largest in Baisinan and the smallest in Hans Muller, which basically coincided with the Shannon index. [conclusion] the comprehensive diversity index of bacterial community structure of grape was closely related to variety and colonization site.
