During a lot of time, it has reported that pine and eucalyptus trees promote ectomycorrhizal formation. However, some species belong to these type of trees may produce arbuscular mycorrhizae. It has been reported that a mycorrhizal root increase about 100 times the absorption of water and nutrients capacity if it is compared to a root without mycorrhizae. There are different sources to obtain the mycorrhizal inoculo for seedling production in nurseries: forest floor, natural or commercial spore, mycelium and nursed plants. In synthesis, the use of mycorrhizae, and the application of cultural and management practices in forest nurseries permit the production of improved seedling witharhigh quality and vigour able to increase field survival and performance. The main objetive en this research is to evaluate the effect of a commercial endomycorrhizal inoculo Glomus intraradices ( BuRIZE®) in the production of improved pine seedlings; as well as, the best inoculation method. 7cm hight Pinus engelmanni seedlings 1 month old was obtained from a nursey bed. Test treatments werw: 1.- Trasplant, 2.- Aspersion, 3.- Sustrate misxture and 4.- Control; with a 100 repetitions per treatment. Ar dosis of 20 ml containing a propagule/ml Was applied to seedlings. Black plastic bag containirs 10 x 20 cm werw used and filled white a peat moss, vermiculite and agrolite mixture in a 3:1:1 proportions. Evaluated variables werw: total seedling height, foliage height, root lenght, secundary roots number, and capiler diameter. he results of adding Glomus intrarradices endomycorrhyzae after 8 months in seedlings caliper diameter for trasplanting treatment (1); these differences were statiscally significant if comparated to control. Vigorous and quality 8 months old seedlings obtained once Glomus intrarradices is applied in forest nurseries, allows to state that a 12 month old pine seedlings are ready to leave nurseries for planting practices and to increase survival rates in the field. Prieto(1998), states that seedling leaving the nurseries must have terminal bud and the caliper diameter must be at least 5mm. Pine seedlings 8 months old obtained in this research improved caliper diameter valves as Prieto stated.Keyworks: endomycorriza, Glomus, Pinus.
