- 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:
- ... 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:
- ... 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:
- ... In 27 C₄ grasses grown under adequate or deficient nitrogen (N) supplies, N-use efficiency at the photosynthetic (assimilation rate per unit leaf N) and whole-plant (dry mass per total leaf N) level was greater in NADP-malic enzyme (ME) than NAD-ME species. This was due to lower N content in NADP-ME than NAD-ME leaves because neither assimilation rates nor plant dry mass differed significantly bet ...

- 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:
- ... Precipitation patterns in the arid southwest U.S. can be highly variable during the summer monsoon season. The ability of germinating seeds to withstand temporary periods of dehydration may determine their potential for successful regeneration under present and future climatic regimes. Germination with short-term hydration and dehydration sequences was compared to constant water potential germinat ...

- Abstract:
- ... Osmotic solutions of polyethylene glycol (PEG) are commonly used to control water potential in seed germination studies. PEG reduces the water potential of osmotic solutions but may limit oxygen availability to germinating seeds. The purpose of this study was to determine whether seed immersion in PEG solution had a detrimental effect on total germination percentage and germination rate of six gra ...

- Abstract:

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 ...

While polyethylene glycol (PEG) solutions have been used to control water potential in numerous seed germination investigations, there is concern that PEG solution-seed contact may reduce seed germination.

- 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 ...
