Digestibility and nitrogen retention in llamas and goats fed alfalfa, C3 grass, and C4 grass hays
The objective of this experiment was to determine the relative digestive capabilities and N retention between goats and llamas fed three forages. Four llamas (2 yrs; 125± 7.3 kg BW) and four Boer-cross goats (2 yrs; 53± 8.4 kg BW) were housed in metabolism crates and fed alfalfa (Medicago sativa; ALF), temperate C3 grass (Festuca arundinacea; C3G) and tropical C4 grass (Cynodon dactylon; C4G) h...
متن کاملPhysiological and Antioxidative Responses of a Halophytic Grass Leptochloa fusca L. Kunth (Kallar grass) to Salinity
The effects of salt stress on growth and some physiological parameters of halophytic plant, Leptochloa fusca L. Kunth, were investigated. The seedlings were irrigated with half-strength Hoagland solution and then treated with different concentrations of NaCl (0, 100, 300, 500 and 700 mM) for 15 days. The fresh and dry weights of both root and shoot were unchanged at 100 mM NaCl and decreased at...
متن کاملHigh C3 photosynthetic capacity and high intrinsic water use efficiency underlies the high productivity of the bioenergy grass Arundo donax
Arundo donax has attracted interest as a potential bioenergy crop due to a high apparent productivity. It uses C3 photosynthesis yet appears competitive with C4 grass biomass feedstock's and grows in warm conditions where C4 species might be expected to be that productive. Despite this there has been no systematic study of leaf photosynthetic properties. This study determines photosynthetic and...
متن کاملPhotosynthetic Characteristics of C3-C4 Intermediate Flaveria
Four species of the genus Flaveria, namely F. anomala, F. liaris, F. pubescens, and F. ramosissima, were identified as intermediate C3-C4 plants based on leaf anatomy, photosynthetic CO2 compensation point, 02 inhibition of photosynthesis, and activities of C4 enzymes. F. anomala and F. rawosissina exhibit a distinct Kranz-like leaf anatomy, similar to that of the C4 species F. trinervia while ...
متن کاملStable-carbon isotope composition of Poaceae pollen: an assessment for reconstructing C3 and C4 grass abundance
Plants using the C3 and C4 photosynthetic pathways differ in carbon-isotope composition, and this difference offers a means to estimate the relative abundance of these two functional groups in the palaeorecord. We report here results of a study aiming to evaluate pollen dC (dCp) of Poaceae (the grass family) as a proxy indicator for palaeoecological studies. On average dCp differs by /13 betwee...
