暗褐网柄牛肝菌半人工模拟栽培及“宿主树”根系上菌丝生长的持久性

Semi-artificial Simulate Cultivation of Phlebopus portentosus and the Durability of Hyphae on Host Roots

摘要:

用暗褐网柄牛肝菌纯培养菌种, 接种盆栽及袋栽的小粒咖啡(Coffea arabica L.)苗、田 间小粒咖啡树的根系, 结果表明：接种 30 d~90 d , 子实体幼蕾紧靠苗(树)的茎基或于茎基四周土壤中生长子实体并发育成熟。子实体单生或丛生, 出菇至成熟3 d~4 d, 单个子实体重20.0 g~62.0 g; 小粒咖啡苗(树)的根茎、主根及侧根被茶褐色的菌索和菌膜包裹, 而根尖及靠近根尖的侧根上没有菌丝和菌索生长或生长很少; 盆栽小粒咖啡苗, 在接种90 d后其根系表面的菌索死亡。

Abstract:

Pure culture of Phlebopus portentosus was inoculated in the roots of coffee tree. The results indicated that the young fruit bodies would come out around the rhizomes of host tree after inoculation in 30 to 90 days, single or cluster, 3 to 4 days for mature, weight 20.0 g to 62.0 g. Brown rhizomorph and hyphae can be seen on the seedlings`rhizome, main root and side root while nothing is on the tip of the root.It was found that rhizomorph on the surface of roots would die after inoculation in 90 days in pot.
