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.

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.

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

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 ...

Environmental control of flowering in tropical ‐ subtropical grasses

Proceedings of the Annual Congresses of the Grassland Society of Southern Africa, 1969
Tropical-subtropical grasses have shown a wide range of response to photoperiod. Some of the response patterns which they exhibit are extremely complex and often seem unrelated to the conditions to which the plants are adapted. However, there is an increasing realisation of the possible role of factors of the environment other than photoperiod in ...

Ionic relations in tropical pasture grasses

Journal of Plant Nutrition, 1981
Abstract Ionic relations in the tops of nine tropical pasture grasses were studied by using K‐Na and K‐Mg nutrient replacement series in sand culture. Rhodes grass, green panic, and pangola grass accumulated Na when K supply was low and Na was available.
