Resumo: | Water deficit throughout the peanut plant development negatively affects physiological processes and reduces its yield. This study aimed to evaluate grain yield, yield components and plant growth of peanut cultivars and breeding lines subjected to water deficit under field conditions. The experimental design was split-plot randomized blocks with three replications. Water deficit treatments (with and without irrigation) were considered the plots and genotypes (IAC Tatu ST, BR1, BRS Havana, Col 72 and Col 82) the subplots. Irrigation was discontinued between 35 and 75 days after emergence on plots subjected to water stress. Plant growth, shoot dry matter and leaf area were negatively affected by drought stress. The difference between plots with and without water stress increased proportionally to the increase in the period of water suppression. The BRS Havana cultivar and the Col 82 breeding line were moderately tolerant to water deficit, with the highest grain yields under stress conditions. Water deficit caused a 68 % reduction in grain yield for the IAC Tatu ST cultivar, 44 % in number of pods per plant for the Col 82 breeding line, 11 % in number of seeds per pod for the Col 72 breeding line and 11 % in the 100 seeds weight for the BRS1 cultivar. |

Este estudo objetivou avaliar o rendimento de grãos, componentes de produção e crescimento de cultivares e linhagens de amendoim submetidas a déficit hídrico, em condições de campo. O delineamento experimental foi o de blocos ao acaso, com parcelas subdivididas e três repetições. Os tratamentos de déficit hídrico (com e sem) constituíram as parcelas e os genótipos avaliados (IAC Tatu ST, BR1, BRS Havana, Col 72 e Col 82) as subparcelas. A irrigação foi suspensa nas parcelas submetidas à deficiência hídrica entre 35 e 75 dias após a emergência. O crescimento das plantas, massa seca da parte aérea e área foliar foram afetados negativamente pelo déficit hídrico. Verificou-se incremento da diferença entre as parcelas com e sem deficiência hídrica, conforme o aumento do período de supressão de água. A cultivar BRS Havana e a linhagem Col 82 apresentaram tolerância moderada à seca, com os maiores rendimentos de grãos em condição de déficit hídrico. O déficit hídrico foi responsável por redução de 68 % no rendimento de grãos na cultivar IAC Tatu ST, 44 % no número de vagens por planta na linhagem Col 82, 11 % no número de sementes por vagem na linhagem Col 72 e 11 % na massa de 100 sementes na cultivar BRS1.Escola de Agronomia - Universidade Federal de Goiás2015-04-17info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionPesquisa Experimental; Métodos Quantitativosapplication/pdfapplication/pdfhttps://revistas.ufg.br/pat/article/view/29652Pesquisa Agropecuária Tropical [Agricultural Research in the Tropics]; v. 45, n. 2, Apr./Jun. 2015; 146-154Pesquisa Agropecuária Tropical (Agricultural Research in the Tropics); v. 45, n. 2, abr./jun. 2015; 146-154Pesquisa Agropecuária Tropical; v. 45, n. 2, abr./jun. 2015; 146-1541983-4063reponame:Pesquisa Agropecuária Tropical (Online)instname:Universidade Federal de Goiás (UFG)instacron:UFGporenghttps://revistas.ufg.br/pat/article/view/29652/18423https://revistas.ufg.br/pat/article/view/29652/18686Copyright (c) 2020 Pesquisa Agropecuária Tropical (Agricultural Research in the Tropics)info:eu-repo/semantics/openAccessArruda, Isabella MendonçaModa-Cirino, VâniaBuratto, Juliana SawadaFerreira, Josué Maldonado2020-07-13T16:16:38Zoai:ojs.revistas.ufg.br:article/29652Revistahttps://revistas.ufg.br/patPUBhttps://revistas.ufg.br/pat/oaiaseleguini.pat@gmail.com||mgoes@agro.ufg.br1983-40631517-6398opendoar:2024-05-21T19:56:06.999889Pesquisa Agropecuária Tropical (Online) - Universidade Federal de Goiás (UFG)true |
