An annotated key to the genera of Lauraceae in the flora Malesiana region
Provedor de dados: 16
Autores: Werff, Henk van der.
Lauraceae are an important component of wet tropical forests and are well represented in the Flora Malesiana region. Their identification has been hampered by two factors: several of the genera are poorly defined and existing keys require both flowers and fruits, which are, however, rarely present together on a specimen. Here a key based almost entirely on flowering specimens is presented, problems in generic delimitation are discussed and vegetative characters helpful in generic identification are listed.

Weed Management and Herbicide Selectivity in Ornamental Plants
Provedor de dados: 87
Autores: MARTINS,D.; MARTINS,C.C.; SILVA JR.,A.C.
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...

International Flower Networks: Transparency and Risks in Marketing Channel Choice
Provedor de dados: 31
Autores: Wijnands,   Jo H.M.; van der Lans,   Karin; Hobbs,   Jill E.
Two thirds of Kenyan cut flowers are marketed through Dutch flower auctions, while the remainder is marketed directly to retailers. Auctions do not restrict the volumes marketed; however price determination is based on a spot market. A Transaction Cost approach is used to investigate the differences in marketing costs between the channels. The results suggest that there are no differences between the channels in terms of uncertainty about prices, finding buyers or transparency of quality standards. Auction growers pay a higher marketing fee but they have significantly fewer office employees and flower varieties compared to growers who market directly.

Directional orientation of reproductive tissue of Eulychnia breviflora (Cactaceae) in the hyperarid Atacama Desert
Provedor de dados: 97
Autores: Warren,Steven D.; Aguilera,Lorgio E.; Scott Baggett,L.
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...

Drought sress and the distribution of vegetative and reproductive traits of a bean cultivar
Provedor de dados: 63
Autores: Nuñez Barrios,Abelardo; Hoogenboom,Gerrit; Nesmith,Dennis Scott.
Soil water deficits may affect the location and pattern of flower and pod production on different stem axes of a bean plant. The objective of this study was to understand the effect of drought stress on the distribution of flowers and pods on the main stem and on branches of bean plants. The experiment was conducted in a shelter field facility. Water stress was imposed from the end of the vegetative stage to physiological maturity and soil water was measured with a neutron probe every two weeks. Formation of flowers at each node of the main stem was monitored at 44 days after planting (DAP) and formation of pods at 55DAP and 65 DAP. Dry weight of stems and leaves as well leaf area were measured during the middle of the pod filling stage (55DAP). The total...

Chemistry Inspired by the Colors of Fruits, Flowers and Wine
Provedor de dados: 42
Autores: QUINA,FRANK H.; BASTOS,ERICK L.
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...

Autores: SILVA,S. S. P.; PERACCHI,A. L.
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.

EFFECTIVENESS OF POSTHARVEST SOLUTIONS FOR THE CONSERVATION OF CUT Oncidium varicosum (ORCHIDACEAE) INFLORESCENCES
Provedor de dados: 64
Autores: Mattiuz,Claudia Fabrino Machado; Mattiuz,Ben-Hur; Rodrigues,Teresinha de Jesus Deléo; Marques,Kelly Magalhães; Martins,Ramilo Nogueira.
The orchid Oncidium varicosum is a tropical plant with significant commercial value due to the beauty of its yellow inflorescences. Several authors have observed a reduction in the water content of cut flowers, consequently, wilting and senescence of petals are the main reasons for the termination of the decorative life of cut flowers. In this research, we studied the effects of several chemical compounds on the postharvest life of cut inflorescences of Oncidium varicosum 'Samurai'. These chemicals are as follows: sucrose (5%) plus 8-hidroxiquinoline citrate (8-HQC) (100 mg L-1) plus silver nitrate (AgNO3) (50 mg L-1); sucrose (5%) plus citric acid (75 mg L-1); quaternary ammonia at 30% (50 mg L-1); and sucrose (5%) plus quaternary ammonia at 30% (50 mg...
