FALCON OCONOR, Emir; RIERA NELSON, Manuel C  y  RODRIGUEZ LEYVA, Orfelina. Effect of the inoculation of mycorrhizal fungi on forest production postures in two types of soils. cultrop [online]. 2013, vol.34, n.3, pp. 32-39. ISSN 0258-5936.

It was developed a study about the influence of two types of micorrizogenos fungus in two types of different soils in forest species. It was on the nursery of Sempre, from de Integral Forest Company Guantánamo. The study took place from January to Mayo 2008 and 2009 in stonemasons of 20 m of long and 1 m of wide. The seeds of Swietenia mahagoni L. Jacq. (Caoba del país) and Lysiloma lastisiliquum Benth. (Soplillo) were seeding on bags of polyethylene in a brown carbonated and fluvisol soil with a proportion of 5:1 and 7:1 of soil bovine organic material. The design was completely randomized and six treatments were done applying 10g of arbuscular mycorrhizal of the Glomus hoi like and Glomus intraradices species below the seeds before the seeding. So, 20 plants of each treatment were evaluated and the growth of each of them was measured too. Besides, the diameter of the shoot the count of the number of leaves, wide of crown, the percent of mycorrhizal infection, the visual density and the mass of the arbuscular endophyte were also evaluated. The results evidenced a positive answer to the inoculation while some differences existed with the non inoculated witness. The combination of the Glomus intraradices + 7:1 with the best results in the brown soil was well observed. Meanwhile, the combination Glomus hoi like + 5:1 for the Fluvisol soid showed the best results.
