Abstract: Increased atmospheric carbon dioxide (CO 2 ) is a consequence of recent anthropogenic environmental changes, and few studies have evaluated its effects on tropical grasses used in Brazilian pastures, the main feed source for major part of ruminant livestock. This study evaluated forage production, chemical composition, in vitro total gas pro‐ duction and organic matter degradability of Brachiaria brizantha under contrasting CO 2 atmospheric conditions in a free air carbon dioxide enrichment (FACE) facility. The forage plants were sown in each of the 12 octagonal rings of the FACE facility: six under ambient atmospheric CO 2 concentration of approximately 390 μmol/mol, here‐ after referred to as control (CON) plots, and other six rings enriched with pure CO 2 flux to achieve a target CO 2 concentration of 550 μmol/mol, hereafter called elevated CO 2 (eCO 2 ) plots. Soil samples were collected to determine carbon and nitrogen con‐ centrations. After seventy days of sowing, a standardization cutting was performed and then at regular intervals of 21 days the forage was harvested (ten harvest dates) and forwarded to laboratorial analyses. Forage above‐ground biomass production (dry matter (DM): 6,143 vs. 6,554 kg/ha), as well as morphological characteristics (leaves: 71% vs. 68%; stem: 28% vs. 31%), chemical composition (crude protein: 162.9 vs. 161.8; neutral detergent fibre: 663.8 vs. 664.3; acid detergent fibre: 369.5 vs. 381; lignin: 60.1 vs. 64.1 g/kg DM; total C: 45.9 vs. 45.9; total N: 2.8 vs. 2.8; total S: 0.2% vs. 0.2%), organic matter in vitro degradability (573.5 vs. 585.3 g/kg), methane (5.7 vs. 4.3 ml/g DM) and total gas (128.3 vs. 94.5 ml/g DM) production did not differ signifi‐ cantly between CON and eCO 2 treatments (p > .05). The results indicated that at least under short‐term enrichment, B. brizantha was not affected by eCO 2 .

ABSTRACT - The objective of this work was to evaluate the bioactive compounds and foliar anatomy of yerba mate (Ilex paraguariensis) morphotypes. The antioxidant capacity, total phenolic compounds, methylxanthines, and caffeoylquinic acids were determined from the aqueous extract of leaves of the following yerba mate morphotypes: "sassafras", dark green, dull green, gray, and "peludinha". Light microscopy and scanning electron microscopy were used to observe the anatomical differentiations. The dark-green morphotype showed the highest contents of caffeine (20.4 mg g-¹), differing significantly only from the "peludinha" morphotype (8.8 mg g-¹). All morphotypes showed similar and high antioxidant activity (886.0 and 588.1 ?mol Trolox equivalent antioxidant activity per gram of sample for ABTS and DPPH, respectively), as well as high total phenolic compounds content (73.9 mg gallic acid equivalent per gram of sample). Although the anatomy of the leaf mesophyll is similar, the wax deposition and cuticle striation configuration on the adaxial surface differ between all five morphotypes.
RESUMO - O objetivo deste trabalho foi avaliar os compostos bioativos e a anatomia foliar de morfotipos de erva-mate (Ilex paraguariensis). A capacidade antioxidante, os compostos fenólicos totais, as metilxantinas e os ácidos cafeoilquínicos foram determinados a partir do extrato aquoso das
folhas dos seguintes morfotipos de erva-mate: sassafrás, verde-escuro, verde fosco, cinza e peludinha. A microscopia de luz e a microscopia eletrônica
de varredura foram utilizadas para observar a diferenciação anatômica. O morfotipo verde-escuro apresenta os maiores teores de cafeína (20,4 mg g-¹)
e difere significativamente apenas do morfotipo peludinha (8,8 mg g-¹). Todos os morfotipos apresentaram atividade antioxidante semelhante e alta (886,0 e 588,1 ?mol de atividade antioxidante equivalente a Trolox por grama de amostra, para ABTS e DPPH, respectivamente) e elevado conteúdo de
compostos fenólicos totais (73,9 mg de equivalente a ácido gálico por grama de amostra). Embora a anatomia do mesofilo da folha seja semelhante, a
deposição de cera e a configuração do estriamento da cutícula na superfície adaxial diferem entre os cinco morfotipos.
