Abstract:

Research on the relationship between soil rhizobacteria of authentic medicinal material Cinnamomum migao and the fruit medicinal active ingredient plays an important role on C. migao cultivation and management and yield improvement of active components. Rhizosphere soils and fruits of C. migao at the junction of Guizhou, Yunnan and Guangxi were collected. High-throughput sequencing technology was used to analyze the gene sequences of soil rhizobacteria of C. migao, soil physicochemical properties and fruit active components were determined as well. As a result, fruit active components 1,8-cineole, α-terpineol and limonene were highest in Tian’e, and cypressene was in Wangmo. Bacterial Shannon index in Wangmo was 6.315 8, higher than other sampling sites. The dominant bacterial phylum in all samples were Proteobacteria, Acidobacteria, Actinobacteria, and Chloroflexi, but it was varied in dominant genera. At the genus level, dominant bacterial genera were mainly affected by pH value and nitrogen content, most genera were positively related with active ingredients. The PICRUST functional prediction results showed that active components were mainly affected by transport and metabolism of bacterial energy and substances, indicating that pH value and nitrogen content in soil could influence the accumulation of fruit medicinal active components by changing rhizophere bacterial diversity.

Key words: Cinnamomum migao H.W.Li, rhizosphere soil, bacterial diversity, medicinal active ingredients
