不同栽培模式下灵芝菌株农艺性状和活性成分研究

了解不同灵芝菌株的差异,探究其最佳的栽培模式,可为灵芝精深加工源头提高优良的栽培品种和栽培模式。通过不同栽培模式对4个灵芝菌株其子实体农艺性状和活性成分进行研究,结果显示,段木栽培中黄灵芝子实体农艺性状表现最好,代料栽培中野生灵芝子实体农艺性状表现最佳;段木栽培中平芝多糖和三萜含量最高;代料栽培中野生灵芝多糖含量最高,而平芝三萜含量最高。灵白、平芝和黄灵芝其多糖和三萜含量段木栽培皆高于代料栽培,野生灵芝其多糖和三萜含量代料栽培明显高于段木栽培。由此可见,不同灵芝菌株适宜于不同的栽培条件和栽培模式,这为选择获得活性成分高的专有灵芝菌株及相应的栽培模式提供参考。

Agronomic Characters and Active Components of Ganoderma lucidum Strains Under Different Cultivation Patterns

To better understand the differences of different Ganoderma lucidum strains and explore the best cultivation model for processing Ganoderma lucidum source to upgrade the fine varieties and improve cultivation patterns, this paper studied the agronomic traits and active constituents of 4 Ganoderma lucidum strains by different cultivation patterns. The results showed that the agronomic traits of Huanglingzhi were the best in cut-log cultivation, and the agronomic traits of wild Lingzhi were the optimum. The contents of polysaccharides and triterpenes were the highest in cut-log cultivation of Pingzhi, and the content of polysaccharides was the highest in bag cultivation of wild Lingzhi. The contents of polysaccharides and triterpenes of Lingbai, Pingzhi and Huanglingzhi in cut-log cultivation were higher than that by bag cultivation, but the contents of polysaccharides and triterpenoids of wild Lingzhi in bag cultivation were significantly higher than that by cut-log cultivation. It indicated seen that different Ganoderma lucidum strains were suitable for different cultivation conditions and modes. These results provided references for selecting Ganodermalucidum strains with high active components, and related cultivation modes.
