Determination of methane yield in cattle fed tropical grasses as measured in open-circuit respiration chambers

Agricultural and Forest Meteorology, 2018
The objective of this study was to determine methane (CH4) yield by crossbred cattle fed tropical grasses. A total of 66 individual determinations of dry matter intake (DMI) and 42 determinations of organic matter intake (OMI) in relation to the ...

Simulated frosting of tropical grasses

Australian Journal of Agricultural Research, 1974
Ranking order for leaf damage was determined in six varieties of the tropical grass setaria after frosting in a controlled environment and was found to be similar to known field response. A frost temperature of –2.5°C provided good discrimination between populations subjected to three successive frost cycles of 4 hr under programmed conditions which ...

CHROMOSOME NUMBERS OF TROPICAL AMERICAN GRASSES

American Journal of Botany, 1967
Chromosome counts are reported for 81 collections of tropical grasses from Suriname, Brazil and the Dominican Republic, these representing 29 genera and 65 species. The records for Bulbulus, Guadua, Homolepis and Piresia are the first for these genera, as are the counts for the 36 following species: Arundinella confinis, Axonopus marginaius, Axonopus ...

Fate of 15N fertilizer applied to maize in rotation with tropical forage grasses

Field crops research (Print), 2019
Tropical forage grasses of the genus Megathyrsus and Urochloa can suppress soil–nitrification by releasing inhibitory substances, reducing N losses and increasing fertilizer N recovery of the cash crop in rotation.

Polysaccharides of tropical grass species. I. Giant star grass (Cynodon plectostachyus)

Carbohydrate Research, 1972
An arabinoglucuronoxylan isolated1 from the leaf and stem of the tropical-pasture species Cynodon plectostachyus contained neutral sugars in molar proportions: D-xylose, 17; L-arabinose, 2.2; and D-glucose, 1. 2-O-(4-O-Methyl-α-D-glucopyrano-siduronic acid)-D-xylose was also present.

Comparative genome analysis between several tropical grasses [PDF]

Euphytica, 1997
Summary The availability of molecular markers allowed comparing genetic maps between distinct taxa. Among the Poaceae (grasses) family, species as divergent as rice, wheat and maize show collinearity within wide regions along the whole genome. This opens the way for the integration of knowledge across all grasses and the development of molecular tools ...

Intake, total-tract digestibility and methane emissions of Texel and Blackbelly sheep fed C4 and C3 grasses tested simultaneously in a temperate and a tropical area

Journal of Cleaner Production, 2018
This experiment was designed to better understand the differences in enteric methane (CH4) emissions of ruminants in tropical and temperate areas.

Acid detergent dispersible lignin in tropical grasses

Journal of the Science of Food and Agriculture, 1994
AbstractThe detergent system of analysis partitions lignin into two fractions: acid detergent lignin (ADL), usually equated with forage lignin, and ‘acid detergent dispersible lignin’ (ADDL), the existence of which has scarcely been recognized, but can be higher than ADL in tropical grasses.

Evidence for Photorespiration in Tropical Grasses

Physiologia Plantarum, 1970
AbstractSugarcane leaves respired in full light and the CO2 evolved could be detected in sorghum or miaze photosynthesizing in the same closed system. A combination of radiometric and infra‐red gas analysis techniques allowed the estimation of photorespiration (total CO2 evolution in light) and photosynthesis at increasing light intensities and of dark
