Resumo: The experiment was carried out aiming to evaluate the gas exchange of dwarf elephant grass genotypes under different hydric conditions, in a randomized design with three replications. Genotypes of dwarf elephant grass (Mott, CNPGL 94-34-3 and CNPGL 92-198-7) were analyzed under two hydric conditions: irrigated (I) and non-irrigated (NI). Differences between treatments I and NI were observed for all genotypes for photosynthesis, stomatal conductance, transpiration and water vapor pressure deficit. Genotype CNPGL 94-34-3 presented highest tolerance to hydric stress, followed by Mott and CNPGL 92-198-7 genotypes. All genotypes presented high photosynthetic rate, under ideal conditions of soil humidity, thus characterizing the analyzed dwarf elephant grass genotypes as plants with high photosynthetic efficiency.

O delineamento experimental foi inteiramente casualizado com três repetições. Foram avaliados três genótipos de capim-elefante anão (Mott, CNPGL 94-34-3 e CNPGL 92-198-7) em duas condições de umidade do solo: irrigado (I) e não-irrigado (NI). Foi observada diferença entre os tratamentos I e NI para todos os genótipos em relação à taxa fotossintética, condutância estomática, transpiração e déficit de pressão de vapor. O genótipo CNPGL 94-34-3 apresentou maior tolerância ao estresse hídrico, seguido pelos genótipos Mott e CNPGL 92-198-7. Todos os genótipos avaliados apresentaram, em condições ideais de umidade do solo, alta taxa fotossintética, caracterizando, deste modo, os genótipos estudados como plantas de elevada eficiência fotossintética.Editora da Universidade Estadual de Maringá2010-03-22info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionpesquisa de campoapplication/pdfapplication/pdfhttps://periodicos.uem.br/ojs/index.php/ActaSciAnimSci/article/view/896110.4025/actascianimsci.v32i1.8961Acta Scientiarum.
