چکیده
El presente proyecto se desarrolló en la Estación Experimental Tropical Pichilingue del Instituto Nacional de Investigaciones Agropecuarias (INIAP) y el Laboratorio Análisis Bromatológico Universidad UTE. Se evaluó efecto fertilización nitrogenada con urea (0, 25, 50 75 kg N ha-1) sobre degradabilidad (biodisponibilidad) ruminal in situ (DIS) los macrominerales (Ca, P Mg) pasto King Grass cosechado a 40 días rebrote. Para análisis estadístico empleó un diseño bloques completos al azar, donde criterios bloqueo fue animal realizó incubación ruminal, respectivamente. Los niveles provocaron cambios biodisponibilidad (degradación) Ca, Mg Pennisetum purpureum las diferentes horas incubación, acción que mayoría casos afectó cinética degradación sus fracciones (Fracción soluble (A), Fracción insoluble pero potencialmente degradable (B), indegradable (c). Potencial (A+B).

Opportunities for Napier Grass (Pennisetum purpureum) Improvement Using Molecular Genetics
Napier grass (Pennisetum purpureum Schumach.) is a fast-growing perennial grass native to Sub-Saharan Africa that is widely grown across the tropical and subtropical regions of the world. It is a multipurpose forage crop, primarily used to feed cattle in cut and carry feeding systems. Characterization and diversity studies on a small collection of Napier grasses have identified a moderate level...

Pearl millet (Pennisetum glaucum (L.) R. Br.) and napier grass (Pennisetum purpureum Schumach) are the most economically important species in the genus Pennisetum. Knowledge of genetic diversity of these two species would enhance their potentials for utilization. The present work assessed the genetic diversity and phylogenetic relationship among Nigerian and Indian accessions of pearl millet an...

The genus Pennisetum (Richard, 1805) includes two economically important tropical forage plants: Pennisetum purpureum (Schumacher, 1827) (elephant grass), with 2n = 4x = 28 chromosomes and genomes A'A'BB, and Pennisetum glaucum (Linnaeus, 1753) (pearl millet), with 2n = 2x = 14 chromosomes and genomes AA. The genetic proximity between them allows hybrids to be obtained (2n = 3x = 21) that yield...

BACKGROUND Elephant grass (Pennisetum purpureum Schumach) and Hybrid Pennisetum (Pennisetum americanum × P. purpureum Schumach) are tall, fast-growing perennial C4 bunchgrasses that have been in recent developed as the most appropriate biomass feedstock in many countries for exploring various biofuel products. However, the challenges of increasing plant biomass yield and enhancing their stress ...

The composition of lipophilic extractives in the cortex and pith of elephant grass ( Pennisetum purpureum Schumach.) stems was thoroughly studied by gas chromatography-mass spectrometry. The predominant compounds were fatty acids followed by sterols (in free and conjugated forms as esters and glycosides). Other steroid compounds, as steroid hydrocarbons and ketones, were also present. Addition...
