| Abstract The aim of this study focused on the construction of the absorption and extraction curves under an aeroponic system for White chrysanthemum cv. Atlantis White, and therefore, propose the periods of maximum and minimum nutrient accumulation from aboveground, root and total biomass. Vegetative cycle of the plant, measured from the day after transplantation (dat) to aeroponic system, and the first day of court lasted 49 days. Evaluations were carried out each week on plants, in absolute competition. For the average aboveground biomass, three replicates were recorded. To obtain total root biomass only one sample, was measured. Therefore, total biomass in average, had achieved 130.9313 g.plant-1, where 72.26% (94.163 g) corresponded to the aboveground... |

| Berberis laurina Billb. (Berberidaceae) is a native shrub from Floresta Ombrófila Mista ecological formation, very ornamental and useful specie for recovery of degraded areas. With medical applications, its fruit is edible and its roots are used as dye. This paper aims to analyze lhe induction of lhe rooting of Berberis laurina stem cuttings employing indolebutyric acid (IBA) in O, 1000 and 2000 mgL-1 concentrations, using the vermiculite as growing medium. In october 2003, stem cuttings were collected from eight stock plants, located in Fazenda Rio Grande - PR. Semi-hardwood cuttings were preppared with 8.0 cm long by 0.35 cm of diameter shape, containing three leaves on the top, cut in a half, the base was cut in diagonal and the top was cut straight,... |

| The objective of this work was to evaluate the effect of indolebutyric acid (IBA) on rooting of Langerstroemia indica cuttings in different substrates. Semi-hardwood cuttings with 7-8 cm were treated in alcoholic solutions of IBA (0, 1,000, 2,000 and 3,000 mg L-1) for 10 s and staked in plastic tubes containing commercial organic substrate or vermiculite. A completely randomized design in factorial arrangement 4 x 2 (4 concentrations x 2 substrates) was used. After 75 days we evaluated percentages of rooted cuttings, with shoots and necrosis, number and length of roots and number of shoots per cutting. IBA in concentration 1,000 mg L-1 promoted best rooting (65.63%) in vermiculite substrate (73.43%). |

| Veintiuna especies de peces arrecifales frecuentes y abundantes en el área de Santa Marta y Parque Nacional Natural Tayrona (Caribe colombiano) se identificaron como promisorias para el mercado de peces marinos ornamentales. La selección se basó en información secundaria y observaciones en campo y laboratorio, dando prioridad a especies o familias que han sido reproducidas exitosamente en confinamiento y que según las observaciones se adaptan satisfactoriamente al cautiverio, con proyección a su futura reproducción, levantamiento y manutención en confinamiento. Así mismo, para algunas de ellas se obtuvieron datos importantes para su acoplamiento y manutención en acuario. Se proponen a Microspathodon crysurus, Coryphopterus personatus, Elacatinus... |

| ABSTRACT: Prunus serrulata is a species widely used in the ornamentation and its economic importance is mainly due to the time of its flowering. The objective was to assess the feasibility of cutting technique for propagating P. serrulata , using stem cuttings from current-year shoots, and to estimate the maximum efficiency concentration of auxin indole butyric acid (IBA), in the promotion of rooting. Collection of plant material took place in late spring. Cuttings were made with about 8±1cm length and two leaves reduced to 50% of its original surface. Twenty one IBA concentrations have been assessed (0, 250, 500, 750, 1000, 1250, 1500, 1750, 2000, 2250, 2500, 2750, 3000, 3250, 3500, 3750, 4000, 4250, 4500, 4750 e 5000mg L-1), applied in base of cuttings,... |

| ABSTRACT: Caesalpinia pulcherrima is an exotic species belongs to the Fabaceae family commonly known as flamboyant-mirim, and widely used for urban forestry. This study aimed to evaluate the effect of different substrates on the emergence and early seedlings growth of C. pulcherrima . The experiment was conducted in a greenhouse belonging to the Centro de Ciências Agrárias, Universidade Federal da Paraíba. The experimental design was completely randomized and treatments had 14 substrates: sand, vegetable soil, vermiculite, wood dust, carbonized rice straw, vegetable soil + sand 1:1, sand + wood dust 1:1, sand + carbonized rice straw 1:1, earth + wood dust 1:1, vegetable soil + carbonized rice straw 1:1, vermiculite + sand 1:1, vermiculite + wood dust 1:1,... |

| ABSTRACT: We aimed to evaluate the rooting potential of Tibouchina sellowiana through the experiments: I - Cuttings from current-year shoots and epicormic shoots were submitted to IBA concentrations: 0, 500, 1000, 1500 and 2000mg L-1, in a factorial arrangement 2 x 5 (two types of cuttings x five IBA concentrations), with four replicates and 20 cuttings each; II - mini-stumps of Tibouchina sellowiana were submitted to successive shoots collecting during the four seasons, in a split-plot design, with five replications of ten mini-stumps per experimental unit. From the shoots of mini-stumps, mini-cuttings were produced, which were initially kept in greenhouse and later transferred to full sun, in a 4 x 5 factorial arrangement (four seasons x five collections... |
