Caracterización anatómica y conductividad hidráulica teórica de los elementos de vaso de variedades silvestres y cultivadas de nopal tunero (Opuntia)

Abstract: Se estudió la morfología y la conductancia hidráulica teórica de elementos de vaso del xilema en cladodios de especies y variedades cultivadas y silvestres de nopal (Opuntia spp.) colectados en las regiones semiáridas de los estados de Jalisco y Zacatecas, con el fin de investigar si las diferencias en la resistencia a la sequía que se observan comúnmente en el campo entre especies silvestres y cultivadas de Opuntia pueden estar relacionadas con divergencias en la densidad, la anatomía de los vasos y en la con… Show more

“…Its leaves are virtually absent and have low sunken stomatal density (20 per mm 2 ), which reduces water loss by transpiration. The growth buds become structures called areolas from where flowers, fruits and thorns are developed; the latter provide protection to avoid predation as well as damage from prolonged exposure to sunlight . Thorns are modified leaves of the cactus and these are composed of cellulose (47.9%), hemicelluloses (48.4%), lignin, ashes, fat and waxes being in very small amounts.…”

Additionally, a cuticle layer covers the surface of each thorn providing protection against desiccation.…”

“…These polymers have the advantage of being regarded as totally natural for many consumers. Many of these polysaccharides, like those from the cactaceae family; specially mucilage and pectins, have been used empirically to modify the rheological properties of some products [4]; they can modulate rheological properties of foods, and are generally used as food thickeners, texture modifier, stabilizers and emulsifiers for various applications.…”
