Resumo: | The gherkin is quite grown in northern and northeastern Brazil by uses water from wells often exhibit high levels of salt. Therefore, this paper aimed to evaluate the behavior of three gherkin cultivars when subjected to salt stress by soaking the seeds and irrigation at different levels of salinity. The treatments were completely randomized in factorial scheme 2 x 3 x 6 (seeds treated with and without pre-soaking in saline solution (5.2 g L-1), three cultivars of cucumber (Northeast, North and 163), and six levels of electrical conductivity of irrigation water (0.65 - control, 1.30, 2.15, 3.0, 3.85, 4.70 dS m-1) with four replications. One assessed the seedling emergence, emergence rate index, shoot length, leaf area, stem diameter and dry mass of shoots. The treatment of pre-germination of seeds of cucumber with saline (5.2 g L-1) provided greater seedling emergence index and emergence rate. On the other hand, the salinity of irrigation water reduced seedling emergence, emergence rate index, shoot length, leaf area, stem diameter and dry matter Air. Cultivars Northeast and 163 stood out as the most tolerant to salinity due to higher estimates of seedling emergence, speed of emergence and shoot dry mass of seedlings. |

Portanto, este trabalho teve como objetivo avaliar o comportamento de três cultivares de maxixe quando submetidas ao estresse salino, por meio da embebição das sementes e irrigação em diferentes níveis de salinidade. Os tratamentos foram instalados no delineamento inteiramente casualizado em esquema fatorial 2 x 3 x 6 (sementes tratadas com e sem pré-embebição em solução salina de NaCl (5,2 g L-1), três cultivares de maxixe (Do Norte, Nordestino e 163), e seis níveis de condutividade elétrica da água de irrigação (0,65 - testemunha; 1,30; 2,15; 3,0; 3,85; 4,70 dS m-1), com quatro repetições de 50 sementes por tratamento. Avaliou-se a emergência de plântulas, índice de velocidade de emergência, comprimento da parte aérea, área foliar, diâmetro do colo e massa seca da parte aérea. O tratamento pré-germinativo de sementes de maxixe com solução salina (5,2 g L-1) proporcionou maior emergência de plântula e índice de velocidade de emergência. Por outro lado, a salinidade da água de irrigação a partir de 2,15 dS m-1 reduziu a emergência de plântulas, índice de velocidade de emergência, comprimento da parte aérea, área foliar, diâmetro do colo e massa seca da parte aérea. As cultivares Nordestino e 163 destacaram-se como as mais tolerantes a salinidade em razão dos maiores valores de emergência de plântulas, índice de velocidade de emergência e massa seca da parte aérea da plântula.UEL2013-12-11info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/1201510.5433/1679-0359.2013v34n6p2753Semina: Ciências Agrárias; Vol. 34 No. 6 (2013); 2753-2762Semina: Ciências Agrárias; v. 34 n. 6 (2013); 2753-27621679-03591676-546Xreponame:Semina.
