| Lilium es una especie de gran importancia económica dentro de la producción y comercialización de flores de corte en el mercado internacional. En condiciones de cultivo en suelo o sustrato, algunos cultivares desarrollan síntomas visuales de quemaduras en hojas jóvenes y problemas de calidad, como flacidez del tallo y menor vida en florero. Estos síntomas se han atribuído a una deficiencia de Ca, e indican que el requerimiento de este nutriente puede ser distinto entre cultivares. Por tanto el objetivo de la presente investigación fue evaluar el efecto del suministro de Ca en el desarrollo y nutrición de Lilium asiático cv. Dream land y Vermeer, y determinar la demanda de Ca de estos cultivares. Los tratamientos fueron la aplicación de soluciones... |

| There are a number of medicinally active phytochemicals isolated from hawthorn with most of the data generated in studies of those species that are native to Europe and Asia. Comparatively little is known about the North American, specifically the Mexican Crataegus species. The objective of this study was to evaluate phenolic compounds, flavonoids and antioxidant activity of extracts of flowers from six Mexican accessions of Crataegus in order to contribute to the chemistry of the Germplasm Bank accessions at the Universidad Autonóma Chapingo. Antioxidant activity was evaluated using DPPH (2,2-diphenyl-1-picrylhydrazyl) method and the flavonoids were identified by HPLC-MS. Quercetin- 3-O-glucoside, quercetin-3-O-rhamnoside, quercetin... |

| Abstract The purpose of this study was to compare the alkaloid profile in different tissues analyzed by GC/MS and to contribute to the ecological knowledge of Calia secundiflora (patol). Samples of leaves, root and seeds of patol (mescal bean) were collected and field information was recorded in the States of Hidalgo and Querétaro, México, using the point-centered quarted method. Species dominance was calculated (value of importance) and the two locations were compared in species richness, similarity index, and soil data. Seventeen species of plants were found in Hidalgo and 21 in Querétaro; Flourensia resinosa and patol dominated the vegetation in Hidalgo, while patol and Dodonaea viscosa dominated in Querétaro. The profile of the quinolizidine alkaloids... |
