Resumo: | Low water availability in semiarid regions affects the development and productivity of agricultural crops. The work analyzed the effects of Salvinia auriculata application as a growth supplement and the activities of the antioxidative enzymes: superoxide dismutase, catalase, ascorbate peroxidase and guaiacol peroxidase on leaves and roots of sunflower seedlings submitted to hydric stress conditions. The experimental design was entirely randomized, arranged in 2x3 factorial arrangement, being two irrigation systems (irrigated and non-irrigated) x three substrates (sand; sand + commercial humus 80 kg N ha-1; sand + Salvinia auriculata 120 kg N ha-1), with eight repetitions. The supplementation with Salvinia auriculata provided higher increments in height, number of leaves and total fresh mass. In addition, there were increases in the activities of the antioxidative enzymes in leaves and roots of sunflower seedlings, deducing that the supplementation with the macrophyte S. auriculata minimized the deleterious effects of hydric stress on the growth of sunflower seedlings. |

El trabajo analizó los efectos de la aplicación de Salvinia auriculata como suplemento en el crecimiento y las actividades de las enzimas antioxidantes: superóxido dismutasa, catalasa, ascorbato peroxidasa y guayacol peroxidasa en hojas y raíces de plántulas de girasol sometidas a condiciones de estrés hídrico. El diseño experimental fue totalmente aleatorio, dispuesto en arreglo factorial 2x3, siendo dos sistemas de riego (regado y no regado) x tres sustratos (arena; arena + humus comercial 80 kg N ha-1; arena + Salvinia auriculata 120 kg N ha-1), con ocho repeticiones. La suplementación con Salvinia auriculata proporcionó mayores incrementos en altura, número de hojas y masa fresca total. Además, se produjo un aumento de las actividades de las enzimas antioxidantes en las hojas y las raíces de las plántulas de girasol, lo que permite deducir que la suplementación con el macrófito S. auriculata minimizó los efectos nocivos del estrés hídrico en el crecimiento de las plántulas de girasol.A baixa disponibilidade hídrica em regiões semiáridas afeta o desenvolvimento e a produtividade das culturas agrícolas. O trabalho analisou os efeitos da aplicação da Salvinia auriculata como suplemento no crescimento e nas atividades das enzimas antioxidativas: superóxido dismutase, catalase, peroxidase do ascorbato e peroxidase do guaiacol em folhas e raízes de plântulas de girassol submetidas às condições de estresse hídrico. O delineamento experimental foi inteiramente casualizado, disposto em arranjo fatorial 2x3, sendo dois sistemas de irrigação (irrigadas e não irrigadas) x três substratos (areia; areia + húmus comercial 80 kg N ha-1; areia + Salvinia auriculata 120 kg N ha-1), com oito repetições. A suplementação com Salvinia auriculata proporcionou maiores incrementos na altura, número de folhas e massa fresca total. Além disso, houve aumentos nas atividades das enzimas antioxidativas em folhas e raízes de plântulas de girassol, deduzindo-se que a suplementação com a macrófita S. auriculata minimizou os efeitos deletérios do estresse hídrico no crescimento das plântulas de girassol.Editora Verde2021-04-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://www.gvaa.com.br/revista/index.php/RVADS/article/view/834010.18378/rvads.v16i2.8340Revista Verde de Agroecologia e Desenvolvimento Sustentável; Vol. 16 No. 2 (2021); 145 - 152Revista Verde de Agroecologia e Desenvolvimento Sustentável; Vol. 16 Núm. 2 (2021); 145 - 152Revista Verde de Agroecologia e Desenvolvimento Sustentável; v. 16 n. 2 (2021); 145 - 1521981-8203reponame:Revista Verde de Agroecologia e Desenvolvimento Sustentavelinstname:Grupo Verde de Agroecologia e Abelhas (GVAA)instacron:GVAAporhttps://www.gvaa.com.br/revista/index.php/RVADS/article/view/8340/10819Copyright (c) 2021 Janacinta Nogueira de Souza et al.info:eu-repo/semantics/openAccessSouza, Janacinta Nogueira deBrito, Paulo Ovídio Batista deFerreira, Gabriela de SousaArruda, Julyanne Fonteles deMatias, Lígia QueirozGondim, Franklin Aragão2022-10-19T14:38:42Zoai:ojs.gvaa.com.br:article/8340Revistahttps://www.gvaa.com.br/revista/index.php/RVADS/PUBhttps://www.gvaa.com.br/revista/index.php/RVADS/oairvadsgvaa@gmail.com || patriciomaracaja@gmail.com || revistaverde1@gmail.com || suporte@antsoft.com.br1981-82031981-8203opendoar:2024-03-06T12:59:44.199589Revista Verde de Agroecologia e Desenvolvimento Sustentavel - Grupo Verde de Agroecologia e Abelhas (GVAA)false |
