FUNGOS ECTOMICORRÍZICOS ASSOCIADOS A ESPÉCIE Eucalyptus dunnii COM RELAÇÃO AO SEU CRESCIMENTO NOS ÚLTIMOS ANOS (2001-2017): UMA REVISÃO INTEGRATIVA

Abstract

Most vascular plants have a mutualistic symbiotic association with mycorrhizal fungi, which improves water and nutrient utilization. Mycorrhizae can be found in various habitats, including degraded areas. The group of mycorrhizal fungi includes several families within the Ascomycota and Basidiomycota phyla, forming a polyphyletic group. Eucalyptus sp. is one of the main forest genera cultivated in Brazil and relies on this symbiosis for better development, particularly Eucalyptus dunnii. When inoculated, it shows increased root length, dry matter production, and phosphorus absorption. This research aimed to conduct an integrative bibliographic review of studies from 2001 to 2017 on the mutualistic symbiosis between Eucalyptus dunnii and soil ectomycorrhizal fungi. To conduct this work, a survey research was performed, considering scientific papers and analyzing techniques, abstracts, results, discussions, and conclusions related to the proposed theme. This included reviewing articles, books, and dissertations, and using keywords such as ectomycorrhizae and Eucalyptus dunnii, electronic platforms such as Google Scholar and Scientific Electronic Library Online (SCIELO), were also utilized. Six studies addressing the proposed theme were found, five of which were conducted in the Southern region of the country and one in the Southeast. All studies emphasized the importance of mycorrhizal specificity and the success of this symbiosis in relation to dry matter production. Despite the scarcity of studies in this area, all had the same results were positive, showing better growth and development of plants exhibiting this interaction, providing better survival for Eucalyptus dunnii even in degraded soils.
