Resumo: | Mathematical models that simulate crop development are important tools to help growers plan management practices and harvest time for cut flowers such as gladiolus. The objective of this work was to validate the PhenoGlad model for the State of Paraná, determining the planting date for marketing flowers for the Day of the Dead, and the quality of the floral stems. The validation of the PhenoGlad model was carried out through field tests in five towns in the State of Paraná, namely: Cascavel, Dois Vizinhos, Marechal Cândido Rondon, Palotina, and Santa Helena. The experiments were carried out during the year 2019. The PhenoGlad model was run for each location and year of meteorological data for the early, The PhenoGlad model was simulated for each location and period of meteorological data available at each weather station in these towns, and for the early, intermediate II, and late development cycles. The planting date was determined through the average of the dates (Julian days) for each simulated year. The variables analyzed were the stages of development according to the phenological scale of the culture, the number of leaves, the average number of florets, and the classification of floral stems according to the quality standards of Veilling Holambra. The PhenoGlad model showed accuracy in simulating the stages of development of gladiolus culture in the state of Paraná and is also suitable for predicting the damage caused by extreme temperatures in floral stems, which was confirmed by the damage caused to sepals and petals of gladiolus in field experiments in the towns of Cascavel, Dois Vizinhos, Palotina, and Santa Helena. The best model performance was observed when simulating the vegetative period of the crop, presenting a low error of 0.54 leaf. In the state of Paraná, for the production of floral stems for the Day of the Dead, the PhenoGlad model simulated the planting dates in the different towns studied from August 1 to August 23. The towns of Cascavel and Marechal Cândido Rondon presented a higher number of florets and higher quality of floral stems than the other towns evaluated. |

O objetivo deste trabalho foi validar o modelo PhenoGlad para o Estado do Paraná, determinar a data de plantio para comercialização de flores para o dia de Finados, e a qualidade das hastes florais. A validação do modelo PhenoGlad foi através de ensaios de campo em cinco municípios do Estado do Paraná, sendo eles: Cascavel, Dois Vizinhos, Marechal Cândido Rondon, Palotina e Santa Helena Os experimentos foram realizados durante o ano de 2019. O modelo PhenoGlad foi rodado para cada local e período de dados meteorológicos disponíveis em cada estação meteorológica das referidas cidades, e para os ciclos de desenvolvimento precoce, intermediário II e tardio. A data de plantio do gladíolo foi determinada por meio da média das datas (dias julianos) para cada ano simulado. As variáveis analisadas foram os estádios de desenvolvimento de acordo com a escala fenológica da cultura, número de folhas, número médio de floretes e classificação das hastes florais de acordo com os padrões de qualidade de Veilling Holambra. O modelo PhenoGlad apresentou acurácia ao simular os estádios de desenvolvimento da cultura do gladíolo no Estado do Paraná e também é apropriado para predizer os danos por temperaturas extremas nas hastes florais, o que se confirmou com os danos causados nas sépalas e pétalas do gladíolo, nos experimentos de campo nas cidades de Cascavel, Dois Vizinhos, Palotina e Santa Helena. O melhor desempenho do modelo foi observado ao simular o período vegetativo da cultura, apresentando baixo erro de 0,54 folha. No Estado do Paraná, para produção de hastes na data de Finados, o modelo PhenoGlad simulou as datas de plantio nas diferentes cidades estudadas de 1 a 23 de agosto. As cidades de Cascavel e Marechal Cândido Rondon apresentaram maior número de floretes e qualidade de hastes superior aos demais municípios avaliadosUEL2023-02-06info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/4670810.5433/1679-0359.2023v44n1p39Semina: Ciências Agrárias; Vol. 44 No. 1 (2023); 39-60Semina: Ciências Agrárias; v. 44 n. 1 (2023); 39-601679-03591676-546Xreponame:Semina.
