Imidazole-4-carboxamide (ICA) and 2-azahypoxanthine (AHX) obtained from Lepista sordida inhibit and promote the growth of herbaceous plants, respectively. In this study, we examined the effects of these compounds on the growth and ectomycorrhizal (EM) colonization of Pinus densiflora seedlings inoculated with Tricholoma matsutake that forms EM associations with pines. The EM colonization by T. matsutake was observed on the root systems of P. densiflora seedlings treated with and without ICA and AHX. The growth of both non-EM and EM P. densiflora seedlings was inhibited by ICA, regardless of the EM colonization. In contrast, AHX promoted the growth of non-EM P. densiflora seedlings, but not of EM seedlings, suggesting that EM colonization interferes with the effect of AHX on P. densiflora growth.

咪唑-4-甲酰胺（ICA）和2- azahypoxanthine（AHX）从获得花脸香蘑抑制和促进草本植物的生长，分别。在这项研究中，我们检查了这些化合物对接种松茸口蘑的松树幼苗的生长和外生菌落（EM）定植的影响，松果与松树形成了EM关联。T对EM的克隆。在P的根系上观察到了松茸。赤松苗具有和不具有ICA和AHX处理。非EM和EM P的增长。丹参不论EM定植如何，ICA均可抑制幼苗生长。相反，AHX促进了非EM P的增长。密西西比树苗，但不包括EM幼苗，这表明EM定植会干扰AHX对P的影响。齿兰生长。
