Resumo: The accumulation of salts in the soil is a common problem of arid and semi-arid regions, that cause reduction in plant growth and yield. In this context, the arbuscular mycorrhizal fungi (AMF) have been studied in recent years, with results indicating that their associations with the plant roots minimize some effects of salt stress. The objective of this work was to evaluate the influence of increasing levels of salinity of the irrigation water in the melon plants mycorrhized with AMF. The experiment design was completely randomized in factorial 2 x 4 corresponding to two mycorrhiza treatments (inoculated and not inoculated plants) x 4 levels of salinity (ECw = 0.5, 1.5, 3.0 and 4.5 dS m-1), with 4 replicates.The mycorhizal colonization, plant growth, leaf gas exchange and the concentrations and contents of ions (N, P, K+, Na+ e Cl-) were measured. The mycorrhized plants showed higher production of shoot dry matter and leaf area, in relation to non-inoculated plants, mainly in the 0.5 dS m-1 treatment. However, this beneficial effect decreased with salinity levels increasing. Stomatal conductance, transpiration rate and photosynthetic rate were positively influenced by AMF, the values being higher in mycorrhized plants. The results showed a peak of colonization in treatment with EC of 1.36 dS m-1 with a tendency to decrease in higher salt concentrations. The symbiotic association between AMF and melon roots increased the contents of N, P and K, at low and medium salinity, and reduced the absorption of potentially toxic ions (Na, Cl) from the salinity caused by irrigation water with 3.0 dS m – 1.

Neste contexto, os fungos micorrízicos arbusculares (FMA) vem sendo estudados nos últimos anos, havendo resultados que indicam que as associações micorrízicas com as plantas minimizam alguns efeitos do estresse salino. O objetivo foi avaliar os efeitos da inoculação dos fungos micorrízicos arbusculares na cultura do meloeiro sob estresse salino. O delineamento experimental utilizado foi o inteiramente casualizado, em arranjo fatorial 2 x 4, correspondendo a 2 tratamentos micorrízicos (plantas inoculadas e não inoculadas) e 4 níveis de salinidade (CEa): 0,5, 1,5, 3,0 e 4,5 dS m-1, com 4 repetições. Foram avaliadas a colonização micorrízica, o crescimento, as trocas gasosas foliares e os teores e conteúdos de N, P, K+, Na+ e Cl- nas plantas. A associação com FMA proporcionou um incremento na produção matéria seca da parte aérea e na área foliar; porém, este efeito benéfico decresceu com o aumento da salinidade. Os FMA também influenciaram de forma positiva a condutância estomática, taxa de transpiração e fotossintética. Os resultados mostraram um pico de colonização na CEa de 1,36 dS m-1 com tendência de redução a partir deste nível de salinidade. Verificou-se ainda que a associação simbiótica entre FMA e meloeiro proporcionou aumento nos totais extraídos de N, P e K+, principalmente nos níveis baixos e médios de salinidade, e redução na absorção dos íons potencialmente tóxicos (Na+ e Cl-) a partir da salinidade da água de irrigação de 3,0 dS m-1.UEL2013-08-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/1067710.5433/1679-0359.2013v34n4p1587Semina: Ciências Agrárias; Vol. 34 No. 4 (2013); 1587-1602Semina: Ciências Agrárias; v. 34 n. 4 (2013); 1587-16021679-03591676-546Xreponame:Semina.
