Resumo: | Parkia platycephala Benth. (Fava-de-bolota) found in areas of Cerrado-Caatinga transition, is a species with potential for feeding ruminants in arid regions. The objective of this study was to evaluate the effect of inoculation of arbuscular mycorrhizal fungi (AMF) on the initial growth and nutrition of P. platycephala Benth. seedlings under water stress. The experimental design was a randomized block design in a 2 × 6 factorial scheme with five replications, consisting of two water regime conditions (with and without stress), four AMF strains (Gigaspora rosea, Gigaspora margarita, Acaulospora koskei, and Acaulospora morrowiae), one treatment with associated inoculum (Mix), and one control. At 120 days after sowing, the morphological variables height (H), stem diameter (SD), number of leaves (NL), root length (RL), total root volume (TRV), shoot dry mass (SDM), root dry mass (SDM) and total dry mass (TDM) were evaluated. Nutrient contents and mycorrhizal colonization rate were also evaluated. The variables NL, SDM and TDM presented significant interaction between inoculation with the fungi and the studied water conditions. For the contents of P, Mg and Mn there was also interaction, being the best results with the strains A. koskei, Mix, A. morrowiae and control, respectively, in the condition without water stress. Mycorrhizal fungi favored plant growth as well as the absorption of P, Mg, Mn and Zn. |

Objetivou-se avaliar o efeito da inoculação dos fungos micorrízicos arbusculares (FMAs) no crescimento inicial e na nutrição da Parkia platycephala Benth. sob estresse hídrico, visando contribuir na produção de mudas de qualidade desta espécie na região Sul do Piauí. O delineamento experimental foi em blocos casualizados em esquema fatorial 2 × 6 com cinco repetições, correspondendo a duas condições de regime hídrico (com e sem estresse); quatro estirpes de FMAs (Gigaspora rosea, Gigaspora margarita, Acaulospora koskei e Acaulospora morrowiae), um tratamento com os inóculos consorciados (Mix) e um controle. Para avaliar o efeito do estresse hídrico adotou-se o método de pesagem dos vasos periodicamente e após a semeadura aos 120 dias foram avaliadas as variáveis morfológicas dos conteúdos de plântulas, taxa de colonização micorrízica, macro e micronutrientes da parte área da planta. As variáveis: NF, MSR e MST apresentaram interação significativa entre a inoculação com os fungos e as condições hídricas estudadas. Os teores de P, Mg e Mn também houve interação, as melhores respostas foram com os inóculos das estirpes A. koskei, o Mix, A. morrowia e o controle, respectivamente, na condição sem estresse hídrico. A taxa de colonização micorrízica foi baixa, porém, a estirpe de A. morrowia foi a que promoveu melhor resultado para esta espécie arbórea. Os fungos micorrízicos frente às condições hídricas estudadas favoreceu o crescimento da planta.CERNECERNE2020-05-13info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://cerne.ufla.br/site/index.php/CERNE/article/view/2296CERNE; Vol. 26 No. 1 (2020); 66-74CERNE; v. 26 n. 1 (2020); 66-742317-63420104-7760reponame:Cerne (Online)instname:Universidade Federal de Lavras (UFLA)instacron:UFLAenghttps://cerne.ufla.br/site/index.php/CERNE/article/view/2296/1174Copyright (c) 2020 CERNEinfo:eu-repo/semantics/openAccessPorto, Dayara LinsArauco, Adriana Miranda de SantanaBoechat, Cácio LuizSilva, Adriano de OliveiraMoitinho, Mara ReginaFarias, Séfora Gil Gomes de2020-05-15T19:57:22Zoai:cerne.ufla.br:article/2296Revistahttps://cerne.ufla.br/site/index.php/CERNEPUBhttps://cerne.ufla.br/site/index.php/CERNE/oaicerne@dcf.ufla.br||cerne@dcf.ufla.br2317-63420104-7760opendoar:2024-05-21T19:54:43.134426Cerne (Online) - Universidade Federal de Lavras (UFLA)true |
