Resumo: | The objective was to develop growth curves for fruit dry mass in Coffea canephora clones, select the best non-linear regression model, estimate the rate of mass gain, analyze differences in fruit development located in the lower, middle and upper thirds of the coffee canopy and generate an equation that describes the process. Eleven data collections were carried out, starting in the pellet phase of nine clones with 30 plants, with 50 fruits being collected in each position of the coffee tree canopies. To obtain the dry matter mass, the fruits were dried in an oven with forced air circulation at 65 °C until constant weight. The mathematical models Brody, Gompertz, Logístico, Mitscherlich and von Bertalanffy were applied. The quality of the equations was evaluated using eight statistical parameters and the confidence intervals of β1, β2 and β3 of the regressions estimated based on the likelihood profile. After selecting the best model, the fruit growth curves were estimated considering the three positions in the coffee canopy. All statistical analyzes were performed in the R software. The Logistic model presents greater reliability to describe the accumulation of dry matter mass in fruits. There were no differences between positions in the coffee canopy. The β3 parameter can be used as an early indicator for Coffea canephora and guide breeding programs. Clones 204, 407 and P1 provided curves with higher quality in relation to the parameters evaluated. |

Se realizaron once colectas de datos, comenzando en la fase de plomo de nueve clones con 30 plantas, colectando 50 frutos en cada posición de las copas de los cafetos. Para obtener la masa de materia seca, los frutos se secaron en estufa con circulación de aire forzado a 65 °C hasta peso constante. Se aplicaron los modelos matemáticos Brody, Gompertz, Logístico, Mitscherlich y von Bertalanffy. La calidad de las ecuaciones se evaluó utilizando ocho parámetros estadísticos y los intervalos de confianza de β1, β2 y β3 de las regresiones estimadas con base en el perfil de verosimilitud. Después de seleccionar el mejor modelo, se estimaron las curvas de crecimiento de frutos considerando las tres posiciones en el dosel de café. Todos los análisis estadísticos se realizaron con el software R. El modelo Logístico es más confiable para describir la acumulación de masa de materia seca en los frutos. No hubo diferencias entre las posiciones en el dosel de café. El parámetro β3 se puede utilizar como un indicador temprano de Coffea canephora y guiar los programas de reproducción. Los clones 204, 407 y P1 proporcionaron curvas con mayor calidad en relación a los parámetros evaluados.Objetivou-se desenvolver curvas de crescimento para massa da matéria seca dos frutos em clones de Coffea canephora, selecionar o melhor modelo de regressão não linear, estimar a taxa de ganho de massa, analisar as diferenças no desenvolvimento dos frutos localizados nos terços inferior, médio e superior da copa do cafeeiro e gerar uma equação que descreva o processo. Foram realizadas onze coletas de dados, iniciando na fase chumbinho de nove clones com 30 plantas, sendo coletados 50 frutos em cada posição das copas dos cafeeiros. Para obtenção da massa da matéria seca os frutos foram secos em estufa com circulação de ar forçada a 65 °C até peso constante. Foram aplicados os modelos matemáticos Brody, Gompertz, Logístico, Mitscherlich e von Bertalanffy. A qualidade das equações foi avaliada por meio de oito parâmetros estatísticos e os intervalos de confiança de β1, β2 e β3 das regressões estimadas com base no perfil de verossimilhança. Após a seleção do melhor modelo realizou-se a estimativa das curvas de crescimento dos frutos considerando as três posições na copa do cafeeiro. Todas as análises estatísticas foram realizadas no software R. O modelo Logístico apresenta maior confiabilidade para descrever o acúmulo da massa da matéria seca nos frutos. Não ocorreram diferenças entre as posições na copa do cafeeiro. O parâmetro β3 pode ser utilizado como um indicador de precocidade para o Coffea canephora e orientar programas de melhoramento. Os clones 204, 407 e P1 proporcionaram curvas com maior qualidade com relação aos parâmetros avaliados.Research, Society and Development2022-03-16info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/2709310.33448/rsd-v11i4.27093Research, Society and Development; Vol. 11 No. 4; e21511427093Research, Society and Development; Vol. 11 Núm. 4; e21511427093Research, Society and Development; v. 11 n. 4; e215114270932525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIporhttps://rsdjournal.org/index.php/rsd/article/view/27093/23836Copyright (c) 2022 João Felipe de Brites Senra; Josimar Aleixo da Silva; Adésio Ferreira; Marlon Dutra Degli Esposti; Uliana Ribeiro Silva; Idalina Sturião Milheiros; Alex Justino Zacariashttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessSenra, João Felipe de Brites Silva, Josimar Aleixo da Ferreira, AdésioEsposti, Marlon Dutra Degli Silva, Uliana Ribeiro Milheiros, Idalina Sturião Zacarias, Alex Justino 2022-03-27T17:17:09Zoai:ojs.pkp.sfu.ca:article/27093Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:44:55.790036Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false |
