目的 筛选诱导降香檀结香的活性真菌。方法 野外条件下,将25株真菌固体菌种分别接种于正常生长的6~7年生降香檀树干上,通过物理表观性状和化学质量初步分析真菌诱导降香檀形成的降香材料,采用分光光度法测定诱导形成降香材料中总黄酮的含量,采用热浸法测定降香醇溶性浸出物的含量。结果 筛选到6株可诱导降香檀形成降香的活性真菌。结论 本实验结果具有重要的理论意义和实际应用价值。
Abstract
OBJECTIVE To select the fungi which can induce Dalbergia odorifera to produce active substances. METHODS Twenty-five fungi were inoculated in the stems of six or seven-year-old D. odorifera under natural conditions. Fungi with biological activity to induce D. odorifera producing active substances were obtained through field screening and chemical quality evaluation. The ethanol-soluble extractives and total flavonoids of D. odorifera were analyzed by spectrophotometry and hot maceration method, respectively. RESULTS Six active fungi inducing the formation of heartwood were obtained. CONCLUSION This study is very important for utilizing fungi in the induction of D. odorifera and sustainable utilization of this special medicinal material.
