Popularly known as araçá-una, Psidium myrtoides is an endemic tree species in Brazil, with fruits much appreciated by the fauna. It is indicated for the composition of reforestation and for enriching the vegetation of degraded areas. This work aimed to evaluate the effects of drought, heat, and the interaction of both in the physiological attributes of Psidium myrtoides plants. Monitored fluorescence, gas exchange, and chlorophyll index in araçá-una plants induced by drought, heat, and the combination of both during 1, 3, and 7 days after treatment induction (DAT). After, the plants were returned to their initial condition, and their recovery was evaluated at 15 DAT. The results indicate that Psidium myrtoides plants reduce photosynthetic activity in the absence of water, contrary to what has been shown in other studies; in addition, they are not potentiated by the combination with heat. Therefore, we conclude that this species has a potential tolerance to heat (Tmean 30.3 °C). However, if water is available in the soil, it maintains photosynthetic activity at normal levels.
