Caracterización química y estomática y crecimiento de tallos de Acanthocereus tetragonus, A. Subinermis e Hylocereus undatus. Colegio de Postgraduados
Juárez Cruz, Aída.
Entre las especies con potencial productivo, sobresalen la cruceta o jacube (Acanthocereus tetragonus), el nopal de cruz (Acanthocereus subinermis) y la pitahaya (Hylocereus undatus.) porque tienen uso como cerco vivo, ornamento, medicina y alimento en diferentes regiones de México. Sin embargo, existe poca información sobre el valor nutritivo y características anatómicas de éstos materiales, principalmente del género Acanthocereus; por lo anterior, la presente investigación tuvo como objetivo generar información que permita sustentar el uso de tallos jóvenes de estas especies como parte de la dieta humana, y también conocer aspectos anatómicos que pueden ser útiles en su manejo agronómico. La investigación se realizó en un huerto ubicado en Tepoztlán,...

Chemical and physical characterization of Opuntia spp. seeds grown in Hidalgo State, Mexico Ciencia e Investigación Agraria
Prieto-García,Francisco; Prieto Méndez,Judith; Acevedo Sandoval,Otilio A; Canales Flores,Roberto A; Marmolejo Santillán,Yolanda.
Nopal fruits (Opuntia spp.) represent a valuable food in various Latin America countries. Typically, the seeds are discarded. However, they could contain basic components that might enable their use as a nutritional supplement or as another product convenient for the food industry. The objective of this paper was to perform a physical and chemical characterization of the seeds of three species of Opuntia (O. Heliabravoana, O. Xoconostle, and O. ficus-indica) to provide data that will help determine their potential use. Fruits were collected in different municipalities of Hidalgo State, Mexico; its seeds were extracted, dried, and analyzed. The results reveal that, except for small differences, the seeds had similarity in the physical characteristics of...

Nutrient content of woody species in the Patagonian steppe, Argentina Boletín de la Sociedad
Barría,Mabel; Crettón,Martina; Gurín,Celeste; Arce,María Elena; Rost,Enrique; Mazzuca,Marcia.
Woody plants constitute a vital food reserve for the herbivores inhabiting the Patagonian steppe. In a preliminary study, some of these plants showed a high content of ether extract (FAT). To determine whether the low availability of nitrogen in soils leads to low forage quality and whether a high FAT content correlates with a high amount of nutritive lipids, namely fatty acids (FA), chemical parameters of forage quality of aerial parts of thirteen woody plants from this steppe were analyzed. Plants showed moderate or low crude protein (CP) content, and, independently of the FAT content, all samples had approximately the same total content of FA (TFA), with an average of 1% of dry matter. The highest CP content was found in aerial parts of Atriplex lampa...

Nutritional and functional characterization of wild and cultivated Sarcocornia neei grown in Chile Ciencia e Investigación Agraria
Riquelme,Javiera; Olaeta,José Antonio; Gálvez,Lena; Undurraga,Pedro; Fuentealba,Claudia; Osses,Andrea; Orellana,Jaime; Gallardo,José; Pedreschi,Romina.
Sarcocornia neei is a halophyte that grows on the coast of the Valparaiso Region of Chile. Studies related to its nutritional and functional value under wild and cultivated conditions are not available. Thus, in this study, a nutritional (complete proximal, mineral and dietary fiber analysis) and functional characterization (total phenolics, β-carotene, hydrophilic and lipophilic antioxidant activity (HAA and LAA) and ascorbic acid) were performed for wild and cultivated plants. Wild plants displayed higher amounts of compounds involved in stress defense mechanisms such as total phenolics, proteins, dietary fiber and ash. The mineral analysis revealed that Na+ and Cl- are the main ions accumulated in wild and cultivated Sarcocornia neei that are...
