    This study was done to assess cultural practices done to increase seedling quality of Pinus cembroides Zucc. grown in a greenhouse at Montecillo, Mexico, and this species' affinity with a group of mycorrhizal fungi (rhizospheric soil), collected from a natural forest of pinion.   Six treatments were  applied  as a result of the interaction between two essential variables:  mycorrhiza (inoculated and no inoculated seedlings) and aerial  pruning (O,  25 and 50%), in greenhouse-grown  seedlings  in containers (156 cm   inoculation was carried out four  months after germination with  a mixture composed  of substrate  and rhizospheric soil.  During transplanting, dry rhizospheric soil was p!aced in contact with the root system.  Five samplings were done, one per month, to evaluate morphological and physiological  variables.   In addition, variables such as quality index and transpiration efficiency were obtained.   Data were analyzed with  ANOVA (P≤0.0001) and a test of means.   The results of the six different treatments obtained from the mycorrhiza-pruning interaction showed that  inoculated, 25%  pruned  seedlings  of Pinus  cembroides  Zucc.  produced  plants with  higher  quality  in terms  of morphology and physiology.   Three species of mycorrhizal fungi were obtained from the inoculum collection site: Clitocybe, Inocybe and Leucopaxillus.
