Resumo: | Two experiments were conducted to evaluate the effect of salinity on early physic nut plant development. In the first trial, physic nut seeds were exposed to seven levels of salinity (0, 2, 4, 6, 8, 10 and 12dS m-1) with eight repetitions, using a substrate of paper soaked with solutions of CaCl2 and KCl. The treatments were evaluated based on the initial germination, total percentage of germination, and time necessary to germination of 50% of the seeds. Increased salinity reduced the first germination count and delayed the time to 50% germination. From 10dS m-1, there was a reduction in germination percentage. The second trial evaluated the effect of salinity on the growth of physic nut seeds. This trial, carried out inside a greenhouse, with a completely randomized design, was composed of five salinity treatments (0.02, 2, 4, 6 and 8dS m-1) with 5 replications. It was observed that salinity levels above 2dS m-1 affected plant development. The current study suggests that salinity management is an important factor to be considered to achieve the potential productivity of physic nut. |

No primeiro ensaio, sementes de pinhão-manso foram expostas a sete níveis de salinidade (0; 2; 4; 6; 8; 10 e 12 dS m-1), com oito repetições, utilizando substrato de papel umedecido com soluções de CaCl2 e KCl. Os tratamentos foram avaliados com base na germinação inicial, porcentagem de germinação total e tempo necessário para germinação de 50% das sementes. O aumento da salinidade reduziu a primeira contagem de germinação e retardou o tempo para 50% de germinação. A partir de 10 dS m-1, houve redução na porcentagem de germinação. O segundo ensaio avaliou o efeito da salinidade no crescimento de mudas de pinhão-‑manso. Este, conduzido em casa de vegetação, com delineamento inteiramente causualizado, foi composto de cinco tratamentos de salinidade (0,02; 2; 4; 6 e 8 dS m-1), com 5 repetições. Observou-‑se que a salinidade acima de 2 dS m-1 afetou o desenvolvimento das plantas. A presente pesquisa sugere que o manejo da salinidade é um importante fator a ser considerado para a obtenção da produtividade potencial do pinhão-manso.Associação Brasileira de Engenharia Agrícola2020-07-14T17:28:01Z2020-07-14T17:28:01Z2013info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfLIMA, L.
