Preprints are preliminary research reports that have not been certified by peer review. They should not be relied on to guide clinical practice or health-related behavior and should not be reported in news media as established information.
Preprints posted online allow authors to receive rapid feedback and the entire scientific community can appraise the work for themselves and respond appropriately. Those comments are posted alongside the preprints for anyone to read them and serve as a post publication assessment.

ABSTRACT
Salinization occurring through irrigation on arable land has been a growing concern worldwide. This study aimed to evaluate the germination and initial development of common rue subjected to different saline concentrations. Two salts (sodium chloride and calcium chloride) and five saline concentrations (zero, -0.1, -0.2, -0.3, and -0.4 MPa) were utilized. Germination tests, first germination count, seedling length and dry weight were employed to assess seed responses to the studied variations. Based on the results, the excess of salt reduces the germination percentage and the initial development of common rue seedlings, regardless of the substance used for stress induction.
RESUMO
A salinização, devido à irrigação em terras cultiváveis, tem sido uma preocupação crescente em todo mundo. Diante disso, objetivou-se com este trabalho avaliar a germinação e o crescimento inicial de arruda submetida a diferentes concentrações salinas. Foram utilizados dois sais (cloreto de sódio e cloreto de cálcio) e cinco concentrações salinas (zero, -0,1; -0,2; -0,3 e -0,4 MPa). As respostas das sementes a essas variações foram avaliadas pelos testes de germinação, primeira contagem de germinação, além do comprimento e massa seca das plântulas. De acordo com os resultados, o excesso de sais reduz a percentagem de germinação e o desenvolvimento inicial das plântulas de arruda, independente da substância utilizada para indução do estresse.
