Resumo: From January to March of 2005 one experiment was developed in a screen house to evaluate the effect of sources and levels of water salinity on emergence and initial development of papaya seedlings cv. Sunrise Solo. A completely randomized experimental design was used and treatments were distributed in a factorial arrangement 3×5, corresponding to three sources (dam water, water salinized with sodium and water salinized with sodium sulfate) and five water saline levels (0.4; 2.0; 4.0; 6.0 e 8.0 dS.m-1) and five replications. At 60 days after seedling emergence the following variables were evaluated: soil electrical conductivity, seedling emergence, plant height, stem diameter and dry mass of shoots and roots. The soil electrical conductivity increased independently of salt source, with more expressiveness for dam water, and all evaluated variables of plant growth were inhibited with water salinity increase.

No período, de janeiro a março de 2005, foi desenvolvido um experimento em abrigo telado para avaliar o efeito de fontes e níveis de salinidade sobre a emergência e desenvolvimento inicial de plântulas de mamão Havaí cv. Sunrise Solo. Os tratamentos foram distribuídos em delineamento inteiramente casualizado, em esquema fatorial 3×5, correspondente a três fontes (água salina de barragem (AS), água concentrada em cloreto de sódio (NaCl) e água rica em sulfato de sódio (Na2SO4) e cinco níveis de salinidade (0,4; 2,0; 4,0; 6,0 e 8,0 dS m-1) em cinco repetições. Aos 60 dias após a emergência foram avaliadas as seguintes variáveis: Condutividade elétrica do extrato de saturação do solo (CEes), % de emergência de sementes, altura de plantas, diâmetro caulinar na altura do colo e biomassa seca de parte aérea e raízes. A CEes do substrato foi elevada, independentemente da fonte utilizada, com maior expressividade para a água de barragem, e as variáveis de crescimento vegetativo avaliadas foram inibidas, independentemente da fonte utilizada, com o incremento da salinidade da água de irrigação.UEL2011-02-10info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/324510.5433/1679-0359.2010v31n4Sup1p1281Semina: Ciências Agrárias; Vol. 31 No. 4Sup1 (2010); 1281-1290Semina: Ciências Agrárias; v. 31 n. 4Sup1 (2010); 1281-12901679-03591676-546Xreponame:Semina.
