Resumo: Banana is one of the most cultivated fruits in tropical countries, however, the banana tree is susceptible to water deficit, with considerable physiological responses. Thus, the objective of this work was to evaluate ecophysiological parameters of seedlings of two banana cultivars grown in different water stress levels. The experiment was conducted at the State University of Maranhão in a completely randomized design with four replications, using a 2×3 factorial arrangement consisting of two banana cultivars (Pacovan-Ken, and Fhia-18) and three water regimes (0%, 67%, and 100% of the field capacity). The cultivar Pacovan-Ken showed better adaptation to the water stress conditions, and presented less damages to the photosynthetic apparatus of the plants, which may be related to the higher canopy cooling capacity of plants of this cultivar.

Dessa forma, este estudo objetivou avaliar o comprometimento ecofisiológio de mudas de duas cultivares de banana sob diferentes níveis de estresse hídrico. O experimento foi conduzido na Universidade Estadual do Maranhão, em delineamento inteiramente casualizado, em esquema fatorial 2 x 3 com quatro repetições. Os tratamentos consistiram de duas cultivares de bananeira: Pacovan Ken e Fhia 18 e três regimes hídricos (0%, 67% e 100% CC), totalizando seis tratamentos. A cultivar Pacovan Ken mostrou ser melhor adaptada às condições do estresse hídrico aplicado, com danos mais tardios à integridade do aparato fotossintético das plantas, o que pode estar relacionado ao fato dessa cultivar apresentar maior capacidade de refrigeração do dossel.Sociedade de Ciências Agrárias de Portugal2019-05-10T00:00:00Zinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articlehttps://doi.org/10.19084/rca.17174eng2183-041X0871-018XRamos, Letícia MouraMeneses, Pedro IvoReis, Fabrício de OliveiraSilva, Benjamim Valentim daReis, Isaias da Silvainfo: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:RCAAP2022-09-06T09:25:13Zoai:ojs.revistas.rcaap.pt:article/17174Portal AgregadorONGhttps://www.rcaap.pt/oai/openaireopendoar:71602024-03-19T15:31:17.757760Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos) - Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãofalse
