Abstract:
... This study characterised 16 tropical perennial grass species in terms of in vitro methane output and related their digestibility and rumen fermentation with methane output. The grass samples were collected, dried in a forced oven, and ground and analysed for nutrient composition. In vitro gas production and organic matter digestibility (IVOMD) were determined using rumen fluid collected, strained ...

Abstract:
... Phosphorus (P) is an important determinant of plant productivity, particularly in the tropical grasslands of Australia, which contain both C₃ and C₄ species. Few studies have compared the responses of such species to P deficiency. Previous work led us to hypothesise that C₃ photosynthesis and the three subtypes of C₄ photosynthesis have different sensitivities to P deficiency. To examine their dyn ...

Abstract:
... With average global temperatures predicted to increase over the next century, it is important to understand the extent and mechanisms of C₄ photosynthetic acclimation to modest increases in growth temperature. To this end, we compared the photosynthetic responses of two C₄ grasses (Panicum coloratum and Cenchrus ciliaris) and one C₄ dicot (Flaveria bidentis) to growth at moderate (25/20 °C, day/ni ...

Abstract:
... • Here, the contribution of stomatal and nonstomatal factors to photosynthetic inhibition under water stress in four tropical C₄ grasses was investigated (Panicum coloratum, Bothriochloa bladhii, Cenchrus ciliaris and Astrebla lappacea). • Plants were grown in well watered soil, and then the effects of soil drying were measured on leaf gas exchange, chlorophyll a fluorescence and water relations. ...

Abstract:
... Australia's tropical grasslands are dominated by C4 grasses, characterized by their unique biochemistry and anatomy. Two naturalized C4 grasses (Panicum coloratum and Cenchrus ciliaris) were used to investigate whether high CO2 partial pressure [p(CO2)] influences photosynthetic nitrogen use efficiency and plant nitrogen use efficiency (PNUE and NUE respectively). Plants were grown for 30 d with f ...

Abstract:
... Models provide a quantitative means to evaluate yield response of forage grasses to applied N and water availability. The objective of this analysis was to estimate model parameters (A, b, c) for bermu. dagrasses and bunchgrasses grown at the same location and during the same time period. The logistic equation was used to relate annual dry matter production to applied N for three bermudagrasses [C ...

Abstract:
... Variation in in vitro fermentation estimates of forage digestibility is a problem. Only a few studies have quantified the extent of laboratory variation, and even less information is available on variability associated with sample collection, processing, and storage prior to analysis. A study was designed to evaluate the effects of source of samples and maturation on genotype selection in a breedi ...

Abstract:
... Kleingrass and buffelgrass are sometimes difficult to establish in the field from seeding because of poor seedling vigor and severe competition from weeds. Greenhouse studies were conducted to evaluate the tolerance of kleingrass (Panicum coloratum L. ‘Selection 75’) and buffelgrass (Cenchrus ciliaris L. ‘Nueces’) seedlings to nine herbicides applied pre and postemergence at rates of 0, 0.28, 0.56 ...
