Production of rocket under salt stress in hydroponic systems

Abstract: Salinity is one of the most limiting abiotic stresses in crop production worldwide. In this study, two rocket cultivars (Cultivada and Folha Larga) were grown in hydroponic system (nutrient film technique) under six treatments. The control comprised a nutrient solution without salt addition, and the other treatments contained different NaCl concentrations in the nutrient solution, resulting in the following electrical conductivities: 1.8, 3.8, 5.8, 7.8, 9.7 and 11.8 dS/m. The experimental design was completely… Show more

“…Santos et al (2012) stated that increasing salinity levels decreased the fresh biomass. Jesus et al (2015) reported that, in two rocket cultivars, increasing salinity reduced the fresh and dry mass of the leaves, roots, and protein content, but proline content was increased and a change of enzyme activity took place. Ashraf (1994) stated that salt tolerant plants produced significantly greater dry biomass than the normal population E. sativa.…”

“…A altura das plantas foi afetada de forma quadrática pelo aumento da condutividade Assim como observado nas demais variáveis, a massa fresca de plantas também apresentou comportamento quadrático em resposta ao incremento na CE da solução aplicada, Em estudos apresentados por alguns autores (Silva et al, 2011(Silva et al, , 2013Jesus et al, 2015), , considerados tóxicos para a maioria das plantas, podendo provocar desequilíbrio nutricional, toxidez ou ambos (Munns, 2005;Munns & Tester, 2008).…”

“…Apesar de sua produção ser realizada predominantemente em cultivo tradicional, atualmente, seu cultivo vem sendo realizado em ambiente protegido, principalmente em sistema hidropônico NFT (Luz et al, 2011;Silva et al, 2011;Jesus et al, 2015) ou em substrato inerte (Santos et al, 2012;Oliveira et al, 2013;Souza Neta et al, 2013).…”

“…Devido à inexistência de estudos desenvolvidos com cada hortaliça em sistema hidropônico, o cultivo de hortaliças, como a rúcula em hidroponia é realizada utilizando solução nutritiva recomendada para a cultura da alface (Silva et al, 2013;Jesus et al, 2015), tendo em vista que a cultura destaca-se como a hortaliça folhosa mais cultivada em sistema hidropônico.…”
