Resumo: | Sunflower (Helianthus annuus L.) is an annual plant with high nutritional and productive value. Among the external factors that influence plant growth, light is one of the most important, as it acts directly on metabolic processes to obtain energy. However, there is a lack of information regarding the ideal light environment for sunflower cultivation, as it limitate the plant growth. Therefore, the objective of this work was to evaluate the influence of light environments on the growth and production of sunflower plants. The experiment was conducted in the greenhouse of the Federal University of Recôncavo da Bahia (UFRB), in a completely randomized design (DIC), with four light environments: full sun (control), red mesh, black mesh and aluminum mesh (both with 50% irradiance) and six repetitions, totalizing twenty-four experimental units. At the end of forty days, physiological growth parameters were evaluated. The data obtained were subjected to analysis of variance, applying the Tukey test, at a 5% significance level. Sunflower plants grown under light environments responded positively to light changes, promoting an increase in plant growth. The greatest growth in height was observed for plants grown in environments under the aluminet and red meshes. The use of black mesh reduced plant growth. The best development of sunflower plants was observed in full sun cultivation and with the use of the aluminet photoconverter mesh. |

Entre los factores externos que influyen en el crecimiento de las plantas, la luz es uno de los más importantes, ya que actúa directamente en los procesos metabólicos para la obtención de energía. Sin embargo, se observa una falta de información sobre el ambiente de luz ideal para el cultivo de girasol, ya que es limitante para el crecimiento de las plantas. Por lo tanto, el objetivo de este trabajo fue evaluar la influencia de diferentes ambientes luminosos en el crecimiento y producción de plantas de girasol. El experimento se realizó en el invernadero de la Universidade Federal do Recôncavo da Bahia (UFRB), utilizando un diseño completamente al azar (DIC), con cuatro ambientes de luz: pleno sol (control), malla roja, malla negra y malla aluminet (ambas con 50% irradiancia) y seis repeticiones, totalizando veinticuatro unidades experimentales. Al cabo de cuarenta días se evaluaron los parámetros fisiológicos de crecimiento. Los datos obtenidos fueron sometidos a análisis de varianza, aplicando la prueba de Tukey, a un nivel de significancia del 5%. Las plantas de girasol cultivadas en ambientes luminosos respondieron positivamente a los cambios de luz, promoviendo un aumento en el crecimiento de las plantas. El mayor crecimiento en altura se observó en las plantas cultivadas en ambientes bajo las mallas aluminet y rojas. El uso de malla negra redujo el crecimiento de las plantas. Se concluye que el mejor desarrollo de las plantas de girasol se observa en el cultivo a pleno sol y con el uso de la malla fotoconvertidora aluminet.O girassol (Helianthus annuus l.) é uma planta anual com alto valor nutricional e produtivo. Dentre os fatores externos que influenciam no crescimento das plantas, a luz é um dos mais importantes, visto que ela atua diretamente nos processos metabólicos para obtenção de energia. Entretanto, nota-se ausência de informações quanto ao ambiente de luz ideal para o cultivo de girassol, visto que ela é limitante no crescimento vegetal. Diante disso, foi desenvolvido um experimento com o objetivo de avaliar a influência dos ambientes de luz no crescimento e produção de plantas de girassol. O experimento foi conduzido na casa de vegetação da Universidade Federal do Recôncavo da Bahia (UFRB), em delineamento inteiramente casualizado (DIC), com quatro ambientes de luz: pleno sol (controle), malha vermelha, malha preta e malha aluminet (ambas com 50% de irradiância) e seis repetições, totalizando vinte e quatro unidades experimentais. Ao final de quarenta dias foram avaliados os parâmetros fisiológicos de crescimento. O maior crescimento em altura foi observado para plantas cultivadas nos ambientes sob as malhas aluminet e vermelha, com um incremento de 22,21 cm e 23,56 cm, respectivamente, em comparação com o controle. A malha aluminet favoreceu o aumento do comprimento da raiz em 36,54 % em relação à malha vermelha. O cultivo de girassol sob pleno sol aumentou a produção de fitomassa, enquanto as malhas preta e vermelha reduziram esse crescimento. Plantas de girassol cultivadas nos ambientes sombreados responderam à modificação do espectro luminoso proporcionado pelas malhas.Uergs2024-04-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://revista.uergs.edu.br/index.php/revuergs/article/view/348010.21674/2448-0479.101.3-12Revista Eletrônica Científica da UERGS ; v. 10 n. 1 (2024): 2024; 3-122448-0479reponame:Revista Eletrônica Científica da Uergsinstname:Universidade Estadual do Rio Grande do Sul (UERGS)instacron:UERGSporhttps://revista.uergs.edu.br/index.php/revuergs/article/view/3480/614Copyright (c) 2024 Cristian Martins de Souza, Gildeon Santos Brito, Alfredo Teles de Jesus Neto, Girlene Santos de Souzahttp://creativecommons.org/licenses/by-nc-sa/4.0info:eu-repo/semantics/openAccessMartins de Souza, CristianSantos Brito, Gildeonde Jesus Neto, Alfredo Teles de Jesus NetoSantos de Souza, Girlene2024-05-02T19:01:30Zoai:ojs.pkp.sfu.ca:article/3480Revistahttp://revista.uergs.edu.br/index.php/revuergs/indexPUBhttp://revista.uergs.edu.br/index.php/revuergs/oai||revista@uergs.edu.br2448-04792448-0479opendoar:2024-05-02T19:01:30Revista Eletrônica Científica da Uergs - Universidade Estadual do Rio Grande do Sul (UERGS)false |
