Título:  Elevated CO2 concentrations alleviate the inhibitory effect of drought on physiology and growth of cassava plants.

Conteúdo:  Due to the rise in anthropogenic greenhouse gas concentrations, the earth's climate is expected to change, with precipitation being reduced in some areas resulting in growth-limiting drought and, as a consequence, reduced plant productivity. We investigated the physiological and growth responses of cassava (Manihot esculenta Crantz) to approximate present-day ambient (390 ?L L?1) and elevated (750 ?L L?1) atmospheric CO2 concentrations under well-watered and water deficit conditions, aiming at understanding how cassava would face those problems. Water deficits led to reductions in the Leaf Elongation Rate of plants grown at ambient as well as CO2-enriched concentrations. However, plants grown at 750 ?L L?1 of CO2 maintained leaf growth two days longer than plants grown at 390 ?L L?1. Three Days After Withholding Water (DAWW), photosynthesis and stomatal conductance were reduced in plants grown under ambient CO2, while in plants under an elevated CO2 concentration, these physiological functions remained similar to that of control plants grown under good water availability. Five DAWW plants grown with 750 ?L L?1 continued to have enhanced gas exchange compared with plants grown under 390 ?L L?1. Under drought stress, the instantaneous transpiration efficiency was always greatest for plants grown under elevated CO2. The positive response of elevated CO2 levels on total dry mass was 61% in the water-stressed plants and only 20% for the plants grown under good water availability.... Mostrar Tudo

Título:  Feeding behavior and physiological parameters of rearing goats fed diets containing detoxified castor cake.

Conteúdo:  Abstract: The objective of this study was to evaluate the influence of replacing soybean meal (SM) with castor bean cake (DCC), detoxified using two alkaline products, on the feeding behavior and physiological parameters of Saanen and Anglo-Nubian goat breeds with an initial body weight of 16.22 ± 0.67 kg. The treatments consisted of three diets that were isoproteic and isoenergetic: the first with a standard formulation based on corn and SM, the second with DCC detoxified using calcium hydroxide (Ca(OH)2 DCC), and the third with DCC detoxified using sodium hydroxide (NaOH DCC). A completely randomized design with a 3 × 2 (diets and breeds) factorial arrangement and four replicates per combination was used. A dietary effect on the intake of dry matter (DM) and NDFap (P = 0.02 and 0.01) was observed, with lower values for goats fed NaOH DCC than the other diets. The diets influenced feeding and rumination times (P = 0.04 and 0.03). An interaction (P = 0.04 and 0.01) between the breeds and the SM-based diet was found for time variables (other activity and idle time). Increased feeding and neutral detergent fiber (NDF) rumination efficiencies were observed for goats fed SM and Ca(OH)2 DCC (P = 0.03 and 0.01). Goats fed the NaOH DCC diet consumed large amounts of water, while Saanen goats urinated more times than did Anglo-Nubian goats. The diets had an effect on the heart rate and rectal temperature (P = 0.01 and 0.02), while the body surface temperature was influenced by the b... Mostrar Tudo
