Resumo: | Abstract The objective of this study was to evaluate gas exchange and production of Maçã bananas type, at different times of the year and the day in semi-arid environment. Seven genotypes genotypes were used: Maçã, Caipira, BRS Tropical, BRS Princesa, YB42-03, YB42-17 and YB42-47, arranged in a completely randomized experimental design with five replicates and four useful plants per plot. For the physiological characteristics, a factorial arrangement 7x7x2 was considered (seven genotypes, seven evaluation periods, two reading times, 8:00 a.m. and 2:00 p.m.). Photosynthetic rates, carboxylation efficiency, and instantaneous water use efficiency are higher at 8:00 a.m., due to meteorological conditions, while foliar temperature and transpiration are higher at 2:00 p.m., due to the elevation of air temperature and low humidity. Months with higher radiation and intermediate temperature provided higher rates of photosynthesis, higher efficiency of carboxylation and photochemistry of photosynthesis. In general, genotype YB42-47 was the most productive, with higher water use efficiency and photosynthesis rates.
