“…Studies on leaf pigment contents suggest that the photosynthetic apparatus adapts to changes in irradiance (Portes et al 2010, Silva et al 2010, Vieira et al 2011, Lage-Pinto et al 2012) throughout leaf development (Rosevear et al 2001). Chls also undergo photooxidation under high irradiance (Hendry andPrice 1993, Araújo andDeminicis 2009).…”

“…Gas exchange was measured at 8:00 a.m. on the same leaves used for extraction of the photosynthetic pigments with a portable infrared gas analyser (IRGA) (LI-6200, LI-COR Inc., Lincoln, USA) in a closed system at 380 ppm CO 2 concentration and 28°C. An artificial light source was used with approximately 1500 lmol m -2 s -1 light intensity (Vieira et al 2011 …”

“…The limitation in the photosynthetic process is influenced by changes in anatomical structures, mainly the thickness of the palisade parenchyma, and stomatal density, in addition to changes in the vascular system, particularly in the xylem and in the density and thickness of the vessels, which control the flow of CO2 and the water entering the plant (Vieira et al 2011). A species with the ability to modify its anatomical structures and its photosynthetic apparatus under different environmental conditions can escape, doing so to avoid serious damage due to stress (Maggio et al 2018).…”
