Comparative Cultivation Experiments of Five Poria cocos Strains in Fujian Province
The cut-log cultivation experiment of five Poria cocos strains was carried out in Fujian region.The sclerotia yield and morphology were compared,and the content of bioactive compositions,nutritional and heavy metals were analyzed.The results showed that,strain 1 and 4 had the higher yield of sclerotia with a relatively good appearance.As for the key active compo-nents,the triterpenoids content of strain 4 was the highest,with 0.28％,and polysaccharide content of strain 3 was the highest,with 1.37％ .The tested five varieties showed varying ability to enrich heavy metals,but the content of all four examined heavy metals were below the limit of the national standard.On the basis of the sclerotia yield,morphology and the content of bioactive compositions,strain 4 could be an elite strain suitable for cut-log cultivation of P.cocos in Fujian region.
