Abstract: R E S U M OA berinjela tem grande importância nutricional e socioeconômica, sendo cultivada e comercializada em vários países, principalmente em ambiente protegido; sua produção, assim como a de inúmeros cultivos agrícolas, é dependente de fatores como água, nutrientes e luz; propôs-se, assim, com este trabalho, avaliar as trocas gasosas, fluorescência da clorofila a e temperatura foliar de berinjela cultivada em ambiente protegido em diferentes lâminas de irrigação. O estudo foi realizado em casa de vegetação… Show more

“…These data corroborate those of Gupta & Thind (2015) and Silva et al (2015), who claim that reduction in stomatal conductance can cause reduction in internal carbon concentration because the greater the stomatal opening, the higher the CO 2 diffusion to the substomatal chamber, and there was a higher correlation between these factors as a function of water availability in the soil.…”

“…This deleterious effect on the EICI, regardless of the proportion of N studied is a consequence of decrease in water absorption due to the reduction in the osmotic potential of the soil solution.. Silva et al (2015) explained that these reductions in EICI are related to decreases in both stomatal conductance and CO 2 assimilation rate, as a consequence of the salt stress, as observed in the present study. Moreover, there is an increase in internal CO 2 concentration ( Figure 3A) in response to the adverse effects of ammonium on plants, according to the previously presented explanation (GUO et al, 2012), since the increase in Ci in detriment of CO 2 assimilation rate promotes reductions in this variable.…”

“…Based on the regression equation, the effects of the different saline levels were more accentuated on plants irrigated using water with ECw of 9.1 dS m -1 and the highest EICI of 0.037 [(µmol m -2 s -1 ) (µmol mol The expressive reduction in EICI observed in cotton plants, cv. 'BRS Rubi', subjected to high ECw levels, suggests that it is probably a reflex of the low rates of CO 2 assimilation ( Figure 2B), in relation to the CO 2 found in the substomatal chamber ( Figure 3A), because, if the internal CO 2 concentration increases and there is a decrease in CO 2 consumption in the chloroplasts, due to the reduction in photosynthetic activity, the EICI ratio will also be reduced (SILVA et al, 2015). In addition, the entry of CO 2 into the leaf mesophyll may have decreased due to the reduction in gs, but the consumption of CO 2 in the chloroplast may have been reduced as well (SUASSUNA et al, 2014).…”
