Abstract: Gas exchange, chlorophyll a fluorescence, and photosynthetic pigments of Xylopia sericea A. St.-Hil. and Siparuna guianensis Aubl. were evaluated during the rainy season and the dry season (2009)(2010) in three understories with different ecological conditions (irradiance, water availability, and temperature) located in the União Biological Reserve (known as REBIO União), at Rio de Janeiro State, a natural forest understory, eucalyptus understory under regeneration, and understory of eucalyptus plantation with… Show more

“…The data show that the main species regenerating in the understory can increase carbon gain and tolerate more irradiance after management. These data in addition to previous studies (Evaristo et al, 2011;Lage-Pinto et al, 2012;Lage-Pinto et al, 2015;Silva et al, 2010;Teixeira et al, 2015;Vieira et al, 2015) show the photoacclimation performance of these species to more irradiance, that could explain their abundance in the open and management areas. Thus, there is a possibility that the management may affect the trajectory of forest regeneration, including potential dominance of these species.…”

“…This suggests that photodamage is reversible in young leaves. Although these species show photoacclimation capacity (Silva et al, 2010;Lage-Pinto et al, 2012;Teixeira et al, 2015;Vieira et al, 2015), dynamic photoinhibition had been observed 1 year after management for S. guianensis and X. sericea in this area (Lage-Pinto et al, 2012). All species are able to photoacclimate,, but B. sericea is the fastest species to recuperate initial conditions after forest management (Teixeira et al, 2015).…”

“…This result suggests that the plants showed very little reduction towards the critical limit, suggesting that they have some evolutionary characteristic to tolerate water shortage. According to the literature, F V /F M decreases under conditions of low water availability, leading to an increase in the photoinhibition processes (Lage-Pinto et al 2012).…”

“…e Siparuna guianensis Aubl. sob três condições luminosas naturais: [1) sub-bosque de floresta natural, 2) sub-bosque de eucalipto sob regeneração e 3) sub-bosque de plantação de eucalipto com árvores de 18 anos que foram removidas um ano antes foi avaliada sob estações de seca e chuva(LAGE-PINTO et al, 2012). Esses autores observaram que, embora ambas espécies pertencem aos estágios iniciais de sucessão ecológica, apresentaram fotoinibição dinâmica após 1 ano de exposição a pleno sol em ambas as estações, acentuadamente na estação seca.…”
