Miles, John W.Maass, Brigitte L.Valle, Cacilda Borges doKumble, V[Brachiaria: biology, agronomy, and improvement]Brachiaria: biology, agronomy, and improvement

Shear strength and grinding resistance of leaves of four species of Brachiaria collected at 4 and 6 weeks of re-growth were determined using modifications of techniques described in the literature. Physical attributes of strength were correlated with analyses of plant cell wall constituents and i...


Herrero, Mario T.Valle, Cacilda Borges doHughes, N.R.G.Sabatel, V. de O.Jessop, N.S.[Measurements of physical strength and their relationship to the chemical composition of four species of Brachiaria]Measurements of physical strength and their relationship to the chemical composition of four species of Brachiaria

Brachiaria species have become important components of sown pastures in the humid lowlands of tropical America. This ecosystem occupies about 50 of Brazil; 60 of the area encompassed by Bolivia, Peru, and Ecuador; 14 of Mexico; and significant areas in other countries of the region. The cultivars...


Pizarro, Esteban A.Valle, Cacilda Borges doKeller-Grein, GerhardSchultze-Kraft, RainerZimer, A.H.[Regional experience with Brachiaria: Tropical America-savannas]Regional experience with Brachiaria: Tropical America-savannas

Two essentials for breeding new cultivars of Brachiaria are germplasm diversity and information on basic biological aspects of major species. This paper reviews current knowledge on the cytological behavior, mode of reproduction and its inheritance, and crossing compatibility of different species...


Valle, Cacilda Borges doSavidan, Yves H.[Genetics, cytogenetics, and reproductive biology of Brachiaria]Genetics, cytogenetics, and reproductive biology of Brachiaria

Until 10 years ago, genetic improvement of Brachiaria species depended entirely on selection among naturally existing genotypes, genetic recombination being impossible because of prevailing apomictic reproduction. However, recent advances in understanding the genetics and cytogenetics of Brachiar...
