The objective of the present work was to evaluate the effect of two efficient stumps of mushrooms mycorrhizal arbuscular on indicators of growth and development in avocado rootstok. One prepares flowing leg composed by 1kg of the biofertilizer EcoMic® that was compound for the stumps of evaluated HMA and 600ml of water. With this leg, the seeds of the treatments 1 and 2 were recovered being conformed the outline in the following way T1: Seeds inoculated with the stump Glomus hoi-like, T2 Seeds inoculated with the stump Glomus mosseae and T3 not inoculated Seeds. You uses a germinator with peanut shell like germination channel; to the 30 days after the germination the plants were taken to bags, which contained a substrate formed by agricultural floor + phlegm with a relationship (75%:25% v.v). The variables of growth and evaluated development were: height of the rootstock, diameter of the shaft, number of leaves, longitude and wide of the leaves, area to foliate and rate of relative growth; inside the parameters micorrízicos you determines the percentage of radical colonization, the visual density and the index of efficiency mycorrhizal. The opposing results demonstrated that the use of efficient stumps of mushrooms mycorrhizal arbuscular; it stimulates the development of the avocado rootstock under nursery conditions that which rebounds in the obtaining of plants of more quality and in turn they constitute a nutritional alternative for this cultivation in those during this phase.
