猪苓菌核生长发育规律观察

The ontogeny of sclerotia of polyporus umbellatus

猪苓菌核外观有白苓、灰苓和黑苓之分。白苓是新生苓,新生苓与老苓之间有黑皮相隔,称之谓分离层。猪苓生长过程中,一年之内可产生1～2个分离层,但无分离层相隔的巨大菌核,是在一年之内生长的,证实人工栽培猪苓时,只要条件适宜猪苓还是可以高产的。

Sclerotia of Polyporus umbellatus Fr. can be dividedto three types, white, grey and black sclerotia.White sclerotia is newly formed by old sclerotia,and there is a black isolator between young sclerotiaand old sclerotia. It is called the separation layer,and one or two of layers could be formed in a scle-rotius in one year. It is produced in one year ifthere is no any separation layer, in a sclerotius ofabout 1 kg, It is possible for P. umbellatus to grow fastunder suitable conditions.
