容器生长的松树幼苗接种营养菌丝体的Pisolithus tinctorius，Laccaria laccata，或P. tinctorius加上saponitic Lepiota lutea种植在墨西哥的高度侵蚀的重新造林网站。3年后，最初定殖于P.tinctorius plus L. lutea的存活率最高。用着色青霉菌群（单独或与L. lutea）的苗高、茎粗和苗体积均大于L.漆树菌根和未接种的幼苗。彩色云杉、彩色云杉+紫穗槐的平均单株体积均高于对照。黄曲霉菌的接种量分别为未接种苗的538和423%。讨论了在墨西哥的造林计划中利用P. tinctorius接种物的潜在效益。
Container-grown pine seedlings inoculated with vegetative mycelium of Pisolithus tinctorius, Laccaria laccata, or P. tinctorius plus the saprophytic Lepiota lutea were outplanted on a highly eroded reforestation site in Mexico. After 3 years, seedlings initially colonized by P. tinctorius plus L. lutea had the highest survival. Seedlings with P. tinctorius mycorrhizae (either alone or with L. lutea) had greater height, stem diameter, and seedling volume than both seedlings with L. laccata mycorrhizae and noninoculated seedlings. The average volume of seedlings with P. tinctorius or with P. tinctorius plus L. lutea was 538 and 423%, respectively, of that of noninoculated seedlings. The potential benefit of utilizing P. tinctorius inoculum in reforestation programs in Mexico is discussed.
