| Tropical grasses has an important role at forage-based cattle production systems. To guarantee production is necessary understand factors that allow plant growth, as well as photosynthesis. Under grazing, the amount of residual leaf area in post-grazing or plant organic reserves also driven the growth. Thus, gaseous exchange responses in forages are essential for understand forage production process, aiming maximum biological efficiency. The objective with this study was to evaluate foliar photosynthesis and water use efficiency in Quênia (Panicum maximum BRS Quênia). The pastures were submitted to intermittent grazing (95% of light interception) with two grazing intensities defined by post-grazing height: high and low (20 and 35 cm). The experiment was... |
