CHROMOSOME NUMBERS OF TROPICAL AMERICAN GRASSES
American Journal of Botany, 1967Chromosome 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, 1969Tropical-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, 1981Abstract 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.

A Study on the Establishment of Tropical Grasses and Legumes
Journal of Agronomy and Crop Science, 1988AbstractThe importance of incorporating compatible legumes into tropical grasslands has been highlighted by many researchers. Thus an experiment was conducted to identify optimum times of establishing tropical grasses and legumes in mixtures. The species selected were Guinea grass (Panicum maximum); Brachiaria (Brachiaria ruziziensis) and Green leaf ...

Growth of tropical and temperate grasses at Palmerston North
New Zealand Journal of Agricultural Research, 1976Abstract Small swards of 14 grasses of tropical origin ( Cynodon dactylon, Digitaria spp., Paspalum dilatatum, Pennisetum clandestinum, Setaria spp.) and 6 of temperate origin ( Dactylis glomerata

Persistence of tropical forage grasses in shaded environments
The Journal of Agricultural Science, 1996SUMMARYThe sowing of improved tropical forages in tree plantations can increase animal productivity considerably, but planted grasses often fail to persist under grazing, resulting in unstable pastures. An experiment was conducted in Brisbane, Australia during the summer of 1989/90 to investigate whether the failure of tropical grasses to persist in ...

Mathematical models for predicting protodioscin in tropical forage grasses
ToxiconProtodioscin is a saponin present in grasses that can lead to losses in animal production. Our hypothesis was that mathematical models can accurately and precisely predict the protodioscin concentration in tropical grasses. We evaluated the ability of four mathematical models to describe the protodioscin concentration in Brachiaria and Panicum ...

Comparative salt tolerance of some tropical and temperate legumes and tropical grasses
Australian Journal of Experimental Agriculture, 1976The dry matter yield of 11 tropical legumes, 10 temperate legumes and 11 tropical grasses was examined in pot experiments on a clay soil with increasing levels of sodium chloride. A mathematical model was fitted to the yield-salt level curves for each species and both the half yield soil salinity level and zero yield soil salinity level were estimated.
