Pisolithus tinctorius and Laccaria laccata were grown in 2 l mason jars and nursery plots previously filled with a mixture of eroded soil and sand were inoculated with 2 jars of each symbiont test. Pinus seedlings were grown into these plots for 30 wk, removed from the soil and growth measured. Only 3 of the 8 pine species tested showed under these adverse conditions a good response to mycorrhizal inoculation; P. pseudostrobus had a growth increase of 144 and 82% when inoculated with the tested fungi. P. radiata showed a growth increase of 79 and 59% with same symbionts inoculation, and P. teocote had a growth increase of 169% only when inoculated with Pisolithus tinctorius. [Pinus ayacahuite, P. douglasiana, P. michoacana, P. montezumae and P. rudis were also studied.].
