Biological species of Armillaria in Japan and its ecological features

为了阐明蜜环菌在日本的生物种类及其生态特征，从研究结果可以看出以下几点：在日本的6种蜜环菌中，有4种是A.gallica、A.ostoyae、A.cepistipes和A.mellea。其中1种与北美生物物种IX （NABS IX）兼容。从核DNA含量的分析来看，蜜铃虫的核相是同型的。3 .通过光照和温度条件的调节，在人工培养基中形成了高卢属（A.gallica）、牛耳属（a.s ostoyae）、蜜耳属（a.s mellea）和甜果属（a.s tabescens）的子实体。在日本红松蜜环菌根腐病受损林分中，蜜环菌是唯一的致病真菌。与此同时，高卢单胞菌和甜蜜单胞菌没有致病性。

To elucidate biological species of Armillaria in Japan and its ecological features, the following facts are evident from the results.1. Among 6 biological species of Armillaria in Japan, four of them are A.gallica, A.ostoyae, A.cepistipes, and A.mellea. And, one of them is compatible with North American biological species IX (NABS IX).2. From the analysis of nuclear DNA content, nuclear phases of A.mellea are considered to be homothallism.3. From the regulation of light and temperature conditions, fruit bodies of A.gallica, A.ostoyae, A.mellea, and A.tabescens are formed in the artificial media.4. At the damaged stands of Armillaria root rot on Japanese red pines, A.ostoyae is only pathogenic fungi. Meanwhile, A.gallica and A.mellea are not pathogenic.
