不同茯苓菌株的菌核产量比较及内在品质评价

Sclerotium Yield Comparison and Internal Quality Evaluation of Different Poria cocos Strains

以从全国收集的12种茯苓菌株为试材,开展栽培试验,比较不同菌株在罗田种植的菌核产量,并测定多糖含量衡量其内在品质,为筛选适合道地产区罗田栽培的茯苓菌株。结果表明:罗田当地菌株LT菌核产量为每窖1.35kg,多糖含量为76.22%,综合表现良好。尽管菌株靖州28和YN 2项指标均优于LT,但栽培试验中二者均不同程度的出现空窖现象。因此,菌株LT依旧是罗田产区栽培的首选菌株,但通过有效的引种驯化,靖州28和YN有望培育成适宜罗田产区栽培的优良菌株。

Taking twelve screened Poria cocos strain from nationwide as material,planting experiment was carried out to compare the sclerotium yield of different strains that cultivated in Luotian and determine the polysaccharide content to measure their intrinsic quality. In order to screen out suitable Poria cocos strains for genuine producing area in Luotian. The results showed that the Luotian local strains LT sclerotium yield was 1.35 kg per cellar, the content of polysaccharide was 76. 22%, comprehensive performance was excellent. Jingzhou 28 and YN the two indicators were better than LT, but both varying degrees appeared empty cellar phenomenon in cultivation experiment. Therefore, currently strain LT should still be preferred strains for cultivation in Luotian region, but through effective introduction and domestication,Jingzhou 28 and YN were expected to grow into excellent strains that suitable for cultivation in Luotian region.
