Resumo: | The agronomic characteristics of sunflower genotypes were evaluated under different plant populations. The experiment was performed at the IFMT experimental field, campus Campo Novo do Parecis, Brazil, between February and June 2015. The experimental design comprised randomized blocks, in a factorial 5 x 5 arrangement, with five sunflower genotypes (AGUARÁ 04, GNZ NEON, HÉLIO 251, SYN 045 and SYN 3950HO) and five plant populations (30,000; 37,500; 45,000; 52,500; 60,000 plants ha-1), with 3 replications. Plant height, stem diameter, capitulum height, capitulum size, achene mass per capitulum, mass of one thousand achenes and achene productivity were assessed. Increase in plant and capitulum height, reduction of stem diameter, capitulum size, achene mass per capitulum and mass of one thousand achenes occurred with increase of plant population. Productivity is correlated with the mass of achene per capitulum and with mass of one thousand achenes. The population of 47,150 plants ha-1 provided the highest achene productivity. |

O experimento foi realizado no campo experimental do IFMT, Campus Campo Novo do Parecis - MT, entre os meses de fevereiro e junho de 2015. O delineamento experimental foi o de blocos casualizados, em esquema fatorial 5 x 5, sendo cinco genótipos de girassol (AGUARÁ 04, GNZ NEON, HÉLIO 251, SYN 045 e SYN 3950HO) e cinco populações de plantas (30.000, 37.500, 45.000, 52.500 e 60.000 plantas ha-1), com 3 repetições. Avaliaram-se as características altura de planta, diâmetro da haste, altura do capítulo, tamanho do capítulo, massa de aquênios por capítulo, massa de mil aquênios e produtividade de aquênios. Há aumento da altura de planta e da altura de capítulo, redução do diâmetro da haste, do tamanho do capítulo, da massa de aquênios por capítulo e da massa de mil aquênios com o aumento da população de plantas. A produtividade está correlacionada com a massa de aquênios por capítulo e com a massa de mil aquênios. A população de 47.150 plantas ha-1 proporciona a maior produtividade de aquênios.Sociedade de Ciências Agrárias de Portugal2019-01-14T00:00:00Zinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articlehttps://doi.org/10.19084/RCA17152eng2183-041X0871-018XStasiak, DiogoDalchiavon, Flávio CarlosBirk, MarcosHiolanda, RosivaldoIocca, Andréia Fernanda SilvaColetti, Admar JuniorCarvalho, Claudio Guilherme Portelainfo:eu-repo/semantics/openAccessreponame:Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos)instname:Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãoinstacron:RCAAP2022-09-06T09:24:42ZPortal AgregadorONG |
