-
摘要: 为筛选获得适宜西藏地区栽培的优质灵芝菌株,以6个不同灵芝菌株为试材,采用袋料栽培,比较分析灵芝菌株主要农艺性状及子实体活性成分含量。多基因测序和聚类分析结果显示菌株15和26均为白肉灵芝;菌株26子实体平均单株质量最高,为82.01 g,菌盖直径最大,为16.00 cm,生物学效率最高,为23.60%;菌株15子实体中三萜含量最高,为1.91%,比药典高出282.00%,菌株26次之,为1.88%,灵芝菌株15子实体中多糖含量最高,为1.27%,菌株26次之,为1.13%,菌株15和26的多糖和三萜含量显著高于其他灵芝菌株,结合主要农艺性状、生物学效率和活性成分含量来判断,白肉灵芝15和26均适宜拉萨地区种植推广。Abstract: In order to select and obtain the high quality Ganoderma lucidum strains suitable for cultivation in Xizang, the main agronomic characters and active components in fruit bodies of 6 different Ganoderma lucidum strains were compared and analyzed by using bag material cultivation. The results showed that strains 15 and 26 were all Ganoderma lucidum. The average single weight of fruiting body of strain 26 was the highest(82.01 g), the diameter of cap was the largest(16.00 cm), and the biological efficiency was the highest(23.60%). The content of triterpenoids in fruitus of strain 15 was the highest(1.91%), which was 282.00% higher than that in pharmacopoeia(1.88%). The content of polysaccharides in fruitus of Ganoderma lucidum strain 15 was the highest(1.27%), which was the highest. The polysaccharide and triterpene contents of isolates 15 and 26 were significantly higher than those of other Ganoderma lucidum strains. According to the main agronomic traits, biological efficiency and active ingredient contents, Ganoderma Lucidum 15 and 26 were suitable for cultivation and promotion in Lhasa area.
