Mycorrhiza. 2004 Dec;14(6):397-400. doi: 10.1007/s00572-004-0322-5. Epub 2004 Aug 20.
While it has been suggested that Matsutake mycorrhizae might not be functional and that Matsutake may behave as a saprobic fungus in soil or even have some pathogenic activity on seedlings, we investigated the consequences of Matsutake inoculation on Pinus densiflora growth. Seventy-five days after inoculation, hyphae were anchored on short roots and well-developed Hartig net palmettis were observed. Compared to both control treatments--seedlings treated with distilled water and seedlings treated with autoclaved mycelium--inoculation significantly stimulated seedling total dry weight by 70.9% and 98.0%, respectively. These findings attest that some type of symbiotic relationship must be functional and favour host growth, ruling out claims of pathogenicity under the sterile conditions used here.
虽然有人认为松茸菌根可能不起作用，而且松茸在土壤中可能表现为腐生真菌，甚至对幼苗有一定致病活性，但我们研究了接种松茸对赤松生长的影响。接种75天后，菌丝附着在短根上，观察到发育良好的哈蒂氏网。与两种对照处理（用蒸馏水处理的幼苗和用高压灭菌菌丝体处理的幼苗）相比，接种分别显著刺激幼苗总干重增加70.9%和98.0%。这些发现证明，某种类型的共生关系一定是起作用的，有利于宿主生长，排除了在此无菌条件下存在致病性的说法。
