Resumo: | Currently, the world is facing many problems of crop production. Among them, water deficit is the most dangerous one. This study aimed at evaluating the possibility of enhancing the water deficit tolerance of common bean plants, during two growth stages, by the exogenous application of hexaconazole. The experimental design was completely randomized, in a factorial arrangement, with three replicates. Hexaconazole (0 mg L-l, 10 mg L-l and 20 mg L-l) was sprayed at flowering (R3), at 60 days after sowing, and at the grain-filling stage (R8), at 90 days after sowing. After the application, the plants were subjected to water deficit by withholding irrigation for seven days. Although all hexaconazole concentrations improved the water deficit tolerance in bean plants, in terms of plant growth and yield, the application of 20 mg L-l provided a better protection, when compared to the other concentrations (p < 0.01). The exogenous application of hexaconazole improved the water deficit tolerance, if compared to non-treated plants, affecting the morphological characteristics, yield components, total chlorophyll, proline, relative water content and enzymatic antioxidants (p < 0.01). The results showed that the hexaconazole-induced tolerance to water deficit in common bean is related to changes in the growth variables and antioxidants. In conclusion, the hexaconazole application could improve the bean growth and yield under water deficit conditions. |

Dentre eles, o déficit hídrico é o mais ameaçador. Avaliou-se a possibilidade de aumentar a tolerância de feijoeiro ao déficit hídrico, durante dois estágios de crescimento, por meio da aplicação exógena de hexaconazole. O delineamento experimental foi inteiramente casualizado, em esquema fatorial, com três repetições. Hexaconazole (0 mg L-l, 10 mg L-l e 20 mg L-l) foi pulverizado na floração (R3), aos 60 dias após a semeadura, e no enchimento de grãos (R8), aos 90 dias após a semeadura. Após a aplicação, as plantas foram submetidas a deficiência hídrica, pela supressão da irrigação por sete dias. Apesar de todas as concentrações de hexaconazole terem melhorado a tolerância à deficiência hídrica, em plantas de feijão, a aplicação de 20 mg L-l proporcionou melhor proteção, em comparação com as outras concentrações (p < 0,01). A aplicação exógena de hexaconazole melhorou a tolerância ao déficit hídrico, em relação a plantas não tratadas com hexaconazole, afetando as características morfológicas, componentes de produtividade, clorofila total, prolina, teor relativo de água e antioxidantes enzimáticos (p < 0,01). Os resultados mostraram que a tolerância ao déficit hídrico induzida por hexaconazole, em feijoeiro, está relacionada com as alterações nas variáveis de crescimento e antioxidantes. Em conclusão, a aplicação de hexaconazole poderia melhorar o crescimento e o rendimento do feijoeiro sob condições de déficit hídrico.Escola de Agronomia - Universidade Federal de Goiás2016-09-23info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionAvaliado por paresapplication/pdfhttps://revistas.ufg.br/pat/article/view/41432Pesquisa Agropecuária Tropical [Agricultural Research in the Tropics]; v. 46, n. 3, Jul./Sep. 2016; 301-310Pesquisa Agropecuária Tropical (Agricultural Research in the Tropics); v. 46, n. 3, jul./set. 2016; 301-310Pesquisa Agropecuária Tropical; v. 46, n. 3, jul./set. 2016; 301-3101983-4063reponame:Pesquisa Agropecuária Tropical (Online)instname:Universidade Federal de Goiás (UFG)instacron:UFGenghttps://revistas.ufg.br/pat/article/view/41432/21721Copyright (c) 2016 Pesquisa Agropecuária Tropical (Agricultural Research in the Tropics)info:eu-repo/semantics/openAccessChehelpar, NasimTohidi-Moghadam, Hamid RezaGhoushchi, Farshad2020-07-13T18:08:31Zoai:ojs.revistas.ufg.br:article/41432Revistahttps://revistas.ufg.br/patPUBhttps://revistas.ufg.br/pat/oaiaseleguini.pat@gmail.com||mgoes@agro.ufg.br1983-40631517-6398opendoar:2024-05-21T19:56:13.661727Pesquisa Agropecuária Tropical (Online) - Universidade Federal de Goiás (UFG)true |
