Influencia del régimen de fertilización y del momento de inoculación en la micorrización de Pinus ponderosa en la etapa de vivero Influence of the fertilization regime and the time of inoculum application in the mycorrhization rate of Pinus ponderosa in nursery

摘要: SUMMARY This paper has the objective to evaluate mycorrhizal colonization percentages and seedling growth of inoculated Pinus ponderosa seedlings, applying Rhizopogon roseolus spores, three fertilization levels, two inoculation moments (two weeks 4 months after sowing), harvest (eight sowing a period under low fertilization, called “lethargy”, 10 sowing). It was found that incorporation “lethargy” significantly increased mycorrhization. Both variation in levels different did not produce significant differences mycorrhization percentages, traditional production regime.
