Abstract: | Las plantas acumulan cuerpos silíceos conocidos como fitólitos. Estos polímeros participan en la reducción del estrés hídrico y salino y afectan la digestibilidad de los forrajes. Por su alta estabilidad, contribuyen a la captura del carbono atmosférico. En este trabajo se caracteriza el contenido de fitólitos en clones y variedades de Cenchrus purpureus. Los fitólitos se cuantificaron por el método de cenizas secas. Los genotipos evaluados se ordenaron en grupos de alto contenido de fitólitos (8.33%), niveles intermedio (6.46%) y bajos (4.37%). Esta distribución facilitará la selección de individuos promisorios para la producción de forraje en regiones con sequía y salinidad. Al mismo tiempo permitirá estimar el impacto ambiental de las variedades que se liberen en términos de su potencial de acumulación de carbono. |
Abstract: | The plants accumulate siliceous bodies known as phytoliths. These polymers participate in the reduction of hydric and saline stress and affect the digestibility of forages. Because of their high stability, they contribute to the capture of atmospheric carbon. In this work, the content of phytoliths in clones and varieties of Cenchrus purpureus is characterized. The phytoliths were quantified by the dry ash method. The evaluated genotypes were arranged into groups with a high content of phytoliths (8.33%), intermediate levels (6.46%) and low levels (4.37%). This distribution will facilitate the selection of promising individuals for the production of forage in regions with drought and salinity. At the same time, it will allow estimating the environmental impact of the varieties that are released in terms of their carbon accumulation potential. |
