A Grass–Fire Cycle Eliminates an Obligate-Seeding Tree in a Tropical Savanna [PDF]

open access: yesEcology and Evolution, 2014
A grass-fire cycle in Australian tropical savannas has been postulated as driving the regional decline of the obligate-seeding conifer Callitris intratropica and other fire-sensitive components of the regional flora and fauna, due to proliferation of ...

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 ...

Ensilage of tropical grasses mixed with legumes and molasses

World Journal of Microbiology & Biotechnology, 1994
The effects of adding two legumes, Gliricidia sepium and Leucaena leucocephala, cv. Cunningham, and molasses on the fermentation characteristics of silages made from two tropical grasses (Pangola grass, Digitaria decumbens, and Setaria sphacelata cv. Kazungula) were investigated.

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

The nutritional value of some tropical grasses

The Journal of Agricultural Science, 1965
1. Twenty feeding and digestibility trials were carried out on seven tropical grasses to determine their nutritional value at different stages of growth, and to study their suitability as possible pasture grasses.2. Content of crude protein was relatively high at immature growth stages of the forages, and declined rapidly with the onset of flowering.3.
