| La floricultura es una de las actividades más importantes del país porque demanda gran cantidad de mano de obra y se considera una de las actividades agrícolas más rentables. Las cadenas productivas son un instrumento que permite conocer y analizar los subsistemas o eslabones que integran un proceso socioeconómico, como: proveedores de insumos (primarios y secundarios), agroindustrias, procesos productivos, unidades de producción-comercialización. Los grupos domésticos agropecuarios pueden ser considerados como el primer eslabón de las cadenas productivas. Existen diferentes tipos de cadenas agropecuarios con necesidades y posibilidades diferenciadas. Los objetivos de la investigación fueron: conocer los tipos de cadenas florícolas que existen en la... |

| La floricultura es la principal actividad agrícola que se realiza en la zona de Texcoco, Estado de México, siendo el crisantemo Dendranthema grandiflorum (Ramat.) Kitam., el cultivo de mayor importancia. Este cultivo, en los últimos años ha presentado problemas en su producción causados principalmente por plagas y enfermedades, siendo los trips una de las plagas más importantes, tanto por los daños directos que causan al alimentarse del cultivo, como por los daños indirectos al transmitir el virus de la marchitez manchada del jitomate. Sin embargo, pocos son los estudios que se han realizado para conocer la diversidad de tisanópteros asociados al cultivo, y su potencial como plagas. El correcto diagnóstico de trips presentes en el cultivo de crisantemo... |

| Black meshes used in greenhouses provide shade to plants, affecting photosynthesis and presenting certain properties that change the microclimatic conditions in these environments. The objective of this study was to evaluate the variation in climate elements in greenhouse cultivated with gerbera (Gerbera jamesonii, Vr. Rambo) in relation to external conditions and the reference evapotranspiration (ETo) at Teresina, State of Piauí, Brazil. The measurements were obtained from July to October 2007 by an automatic data acquisition system installed inside and outside the greenhouse. The global solar radiation, evapotranspiration, precipitation, temperature, relative humidity, and wind speed were estimated. The results showed that major effect of the shading... |

| The soaking curve and the effect of temperature on the germination of daisy seeds (Chrysanthemum leucanthemum) were characterized in this study. To determine the soaking curve, four samples of 0.5 g of seeds were soaked in germitest paper moistened with distilled water and maintained in germinator at 25ºC. The seeds were weighed in periods of 0, 3, 6, 9, 12, 24, 36, 48, 60, 72, 84 and 96 hours using a precision digital balance of 0.0001 g. A triphasic pattern germination curve was adjusted, allowing the determination of the beginning and duration of the phase II of the germination process. The germination test was carried out with four replications of 50 seeds disposed in "Gerbox" boxes and placed in germinators at the temperatures of 20, 25, 30 or... |

| The quality and the profitability on floriculture are intimately linked to the adequate plant nutrition. In the present research we aimed to evaluate the electrical conductivity (EC) and pH of the substrate solution on four different gerbera cultivars subjected to fertigation, with two nutritive solutions. The experiment was carried out in a greenhouse, from May to July 2006, on the Universidade Estadual Paulista, Botucatu, São Paulo state, Brazil. The experiment was carried out under an experimental design of random blocks, in 4×2 factorial arrangement, with four Gerbera cultivars (Cherry, Golden Yellow, Salmon Rose and Orange) and two nutritive solution concentrations: 0.92 and 1.76 dS m-1 EC) during the vegetative stage, and 1.07 and 2.04 dS m-1 during... |

| Establishment of germplasm banks of ornamental species, together with breeding programs is fundamental for the growth of competitive cultivars of flowers that are the same or better quality than those developed in other countries. Around 100 progenies from a crossing between the cultivars Dendrobium 'Tong Chai Gold' and Dendrobium 'Black Jack' were obtained, from 50 plants which were selected and grown in pots in greenhouse conditions to evaluate the blooming stage and to select the progenies. Selection of vigorous growing plants and without disease symptoms were made in the period of cultivation. Also, there were evaluated the growing characteristics, rooting, early blooming, as well as the color, number and size of flowers in the first and second... |

| Species of the orchidaceae family are grown for marketing flowers and among them the genus Cattleya stands out. However, due to its slow growth, the substrate is subjected to weed infestation. Therefore, this study aims to evaluate the selectivity and efficiency of herbicides in controlling Pilea microphylla in Cattleya orchid seedlings (Cattleya tenebrosa x Cattleya leopoldy). We used a completely randomized design with four replications. The evaluated herbicides were oxyfluorfen (0, 120, 240 and 480 g ha-1), flumioxazin (0, 12.5, 25 and 40 g ha-1), nicosulfuron (0, 20, 40 and 80 g ha-1) mesotrione (0, 96, 144 and 192 g ha-1), clethodim (0, 60, 84 and 108 g ha-1) and metsulfuron-methyl (0, 1.2, 1.8 and 2.4 g ha-1). At post-emergence applying time, the... |

| 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... |

| This study investigated the cost structure of the floriculture industry in the United States. Economies of scale and input elasticities were estimated with a normalized quadratic cost function. Results suggest that economies of scale exist in the floriculture industry. As producers become large and more automated, they have a cost advantage relative to smaller producers who are producing the same output product mix. The existence of economies of scale suggests that average grower size can increase in the future as growers increase in size to take advantage of cost efficiencies. |

| The idea of territory comprises a complex relationships net, its dynamics is understood by the geographical proximity, the rural agroindustry organization (AIR) and the way in which all of them are related with territory external actors. Despite the fact that between territory actors exist differences, collective action theory focuses on the actor´s capacity to group in order to reach common goals, and from these goals, manage their resources, creating opportunities and/or benefits for the group; the success or failure of collective action strategies depends on internal or external factors and it also depends on the context in terms of territory. The presence of trust and cooperation favors the structural collective action and may promote an increase in... |

| In the best cultivation methods of orchids, in particular of the genus Phalaenopsis, liming is a common practice. The objective of this study was to evaluate the influence of lime rates (0.0; 1.0; 2.0; 3.0; 4.0; and 5.0 g dm-3 of substrate) applied to the cultivation substrate (xaxim) on the growth of Epidendrum ibaguense seedlings. In a greenhouse, 1-L plastic pots filled with 0.8 dm³ of xaxim were irrigated such that no leachate was lost during the experiment. N, P, K, Ca, Mg, S, Fe, Zn, B, and Mn contents in roots, stems and leaves were measured. Leachate was collected by applying a sufficient water volume to obtain 25 mL from each pot. Fourteen days after lime application of 3 g dm-3, the pH of the collected leachate reached values above 7 and a value... |

| ABSTRACT This study aimed to evaluate the effect of nitrogen (N) and potassium (K) fertilization in yield and contents of macronutrients in heliconia plants (Heliconia psittacorum x Heliconia spathocircinata Aristeguieta) cv. Golden Torch. The experiment was set in a randomized block design, in a 4 x 4 factorial, corresponding to N doses (0, 120, 180 and 240 g of N hole-1) and K doses (0, 120, 180 and 240 g of K2O hole-1) with four replicates and five rhizomes per plot, under field conditions. After one year of cultivation, yield (number of flower stems per square meter) and the leaf contents of N, P, K, Ca, Mg and S were determined. The applied N doses did not influence either yield or the leaf contents of the evaluated macronutrients. K fertilization... |
