ABSTRACT. The objective of this study was to evaluate the effects of a biostimulant on gherkin seeds, cultivar Liso de Calcutá, under conditions of salt stress. A split-plot experimental design with five replications was used; the main plot was represented by two levels of irrigation water salinity (0.5 and 3.5 dS m -1 ), and the subplot was composed of five biostimulant doses applied as a seed treatment (0, 5, 10, 15, and 20 mL kg -1). The following variables were evaluated: the number of leaves; number of branches; length of the largest branch; leaf, stem, fruit and total dry matter; number of fruits; average fruit weight; and fruit production. The values of all analyzed variables decreased with an increase in irrigation water salinity regardless of the biostimulant dose, but in the absence of salt stress, biostimulant use led to an increase in the number of leaves and branches, the length of the largest branch and biomass accumulation. Biostimulation was not effective in reducing the effects of salinity on gherkin production, but it increased fruit production regardless of the salinity level.

“…O efeito do bioestimulante sobre a MST é resultante da resposta já apresentada para as demais variáveis de biomassa (MSC, MSF, MSR, MSP), e está em concordância com estudos desenvolvidos por outros autores em diferentes espécies de interesse agronômico, como milho (BARBIERI et al, 2014;SANTOS et al, 2013), maracujá (ECHER et al, 2006;FERRAZ et al, 2014), soja (KLAHOLD et al, 2006), feijão comum (ÁVILA et al, 2010), entre outras. Na Figura 2F é apresentada a resposta aos tratamentos aplicados sobre a área foliar específica (AFE), na qual se verifica que não houve efeito significativo da aplicação de Stimulate ® sobre a AFE na ausência de estresse salino (0,5 dS m -1 ), obtendose AFE média de 301,9 cm 2 g -1 MSF.…”

“…No entanto, alguns autores já relataram que o efeito benéfico de bioestimulantes tem sido inibido em plantas cultivadas sob estresse hídrico (ÁVILA et al, 2010) ou salino (BARBIERI et al, 2014;OLIVEIRA et al, 2013). Diante do exposto, este trabalho foi desenvolvido com o objetivo de avaliar o desenvolvimento inicial do milho pipoca em função do tratamento de sementes com bioestimulante Stimulate ® e uso de água salina.…”

) e quatro doses de bioestimulante aplicado via tratamento de sementes (0; 5; 10 e 20 mL kg -1 de sementes), com cinco repetições. Utilizou-se o bioestimulante comercial Stimulate ® (0,009% citocinina, 0,005% giberelina e 0,005% de auxina) e as plantas foram coletadas aos 50 dias após a semeadura. Foram avaliadas as seguintes variáveis: altura de plantas, diâmetro do colmo, número de folhas, área foliar, massa seca de colmo, massa seca de folhas, massa seca de raiz, massa seca de pendão, massa seca total e área foliar específica. O uso de água salina na irrigação provocou redução na maioria das variáveis de crescimento do milho doce, independentemente do tratamento de sementes com bioestimulante. O tratamento de sementes com Stimulate ® promove o desenvolvimento de plantas de milho pipoca, mais não inibiu nem amenizou o efeito da salinidade sobre as plantas. Palavras-chave: Zea mays.

However, studies on the use of these substances in plants under stress are still being developed, especially for salt stress. The aim was to evaluate the use of bio-stimulants to relieve salt stress in popcorn. The experiment was carried out in a greenhouse on the campus of the Federal Rural University of the Semi-Arid in Mossoró, in the State of Rio Grande do Norte, Brazil. A completely randomised design was used, with treatments distributed in 2 x 4 factorial scheme, representing two levels of salinity of the irrigation water (0.5 and 4.5 dS m -1 ) and four levels of biostimulant, applied by seed treatment (0, 5, 10 and 20 ml kg -1 seed), with five replications. The commercial biostimulant Stimulate® was used (0.009% cytokinin, 0.005% gibberellin and 0.005% auxin), with the plants being harvested 50 days after sowing. The following variables were evaluated: plant height, stem diameter, number of leaves, leaf area, stem dry weight, leaf dry weight, root dry weight, tassel dry weight, total dry weight and specific leaf area. The use of saline water for irrigation caused a reduction in most growth variables in the sweet corn, regardless of seed treatment with biostimulants. Seed treatment with Stimulate® promotes development in popcorn, but did not inhibit or lessen the effect of salinity on the plants.

“…Tal fato reforça os resultados obtidos por Oliveira et al (2013), os quais observaram que o uso do bioestimulante Stimulate ® não afetou o crescimento em plantas de feijão caupi submetidas ao estresse salino. Outros autores também constataram que o efeito do bioestimulante pode ser influenciado por fatores genéticos (Bertolin et al, 2010) e ambientais (Baldo et al, 2009;Ávila et al, 2010;Albrecht et al, 2012;Oliveira et al, 2013).…”

R E S U M OO uso eficiente de água salina depende da tolerância da cultura e da adoção de tecnologia que reduzam o efeito da salinidade. O trabalho foi desenvolvido em Mossoró-RN, para avaliar o uso do bioestimulante Stimulate ® e da salinidade na cultura do feijão caupi. O delineamento experimental utilizado foi o inteiramente casualizado em esquema fatorial 4 × 4, sendo quatro concentrações salinas na água de irrigação (0,5; 2,0; 3,5 e 5,0 dS m , grain yield and harvest index. Statistical analysis of the data revealed that there was significant interaction between the factors for most variables. The use of high concentrations of growth promoter enhances the deleterious effects of salinity, as well as the use of irrigation water of high salinity inhibits the beneficial effect of plant growth regulator in crop yield. The use of biostimulant Stimulate ® with concentrations of 0.5 to 0.75 L ha -1 provides an increase in grain yield of cowpea, provided that irrigation is performed with water of electrical conductivity less than 3.5 dS m -1 .
