| ABSTRACT An overview is provided of the status of research at the frontiers of investigation of the chemistry and photochemistry of two classes of natural plant pigments, the anthocyanins and the betalains, as well as of the pyranoanthocyanin pigments formed from anthocyanins during the maturation of red wine. Together, anthocyanins and betalains are responsible for almost all of the red, purple and blue colors of fruits and flowers and anthocyanins and pyranoanthocyanins are major contributors to the color of red wines. All three types of pigments are cationic below about pH 3, highly colored, non-toxic, reasonably soluble in water or alcohol and fairly stable to light. They exhibit good antioxidant or antiradical activity and, as part of our diet, confer... |

| BACKGROUND: Many barrel or columnar cacti, including some in the Atacama Desert, produce their reproductive tissue at or near the terminal apices of solitary or minimally branched stems that lean toward the equator, reportedly to maximize exposure to photosynthetically active radiation (PAR). Those with lateral reproductive tissue, often produce the tissue on the equatorial side of the stems. An examination of the multi-stemmed, arbuscular cactus, Eulychnia breviflora, was made to determine if it follows the same general strategy. METHODS: Individuals of the species were evaluated along a 100 km transect in the Atacama Desert. The position of all floral buds and open flowers was documented relative to the center of the plants and relative to the center of... |

| O presente artigo, com base em uma pesquisa bibliográfica, traça um panorama do agronegócio de flores e plantas ornamentais no Brasil. Ressalta os principais aspectos do setor como produção, mercado consumidor e dificuldades. A floricultura vem se expandindo consideravelmente, antes restrita a região Sudeste, principalmente no Estado de São Paulo, hoje se encontra em todas as regiões do País, graças ao trabalho de diversas Instituições que acreditam no potencial desse segmento. Um dos aspectos que contribui para a expansão são as condições climáticas do Brasil que favorece o cultivo de flores de clima temperado e tropical. Em função dessa diversidade climática é possível produzir internamente flores, folhagens e outros derivados, todos os dias do ano a um... |

| En relación a la siembra directa el trasplante en el cultivo de chile permite el uso eficiente de semillas, uniformidad en la población y seguridad en la producción. Sin embargo, dicha producción dependerá de la edad de la plántula al trasplante. El objetivo del presente estudio fue evaluar el crecimiento y rendimiento de dos cultivares de chile Guajillo (Capsicum annuum L.) Apaxtleco y Mirasol en función de la edad al trasplante, el manuscrito se presenta en 4 capítulos: Capítulo I. Crecimiento y rendimiento de chile guajillo Apaxtleco y Mirasol en función de la edad al trasplante bajo condiciones de invernadero, en donde se establecieron 3 fechas de trasplante a los 15, 30 y 45 días después de la emergencia (dde). Capítulo II. Crecimiento y... |

| 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... |

| In the present study visits of phyllostomid bats to the Lafoensia glyptocarpa Kohne flowers were observed at Federal Rural University of Rio de Janeiro, Itaguaí municipality, Rio de Janeiro state. This tree species present floral characteristics to fit the "chiropterophilous syndrome", encouraging the visit of four species of bats which showed different behavior patterns, according to their size, weight and access to the food resources. Glossophaga soricina (Pallas, 1766) showed hovering behavior. Phyllostomus hastatus (Pallas, 1767) and Platyrrhinus lineatus (Geoffroy, 1810) showed landing behavior and Artibeus lituratus (Olfers, 1818) fed during the quick flight, without a real landing. |

| ABSTRACT: Floriculture and landscaping sector has the same problems as other crops regarding weed management. Weeds affect the yield and quality of the harvested product, in which the visual aspect and aesthetics stand out as the most important factors in flower production and landscaping. Weed control in floriculture and landscaping is critical and costly because maintaining the beauty of the product and the use of herbicides is a low-cost management tool compared to manual management. However, it implies knowing herbicide selectivity, as ornamental species may present some injury depending on the active ingredient and the degree of selectivity of the compound. Because the use of this practice in flower production and landscaping both abroad and mainly in... |
