ABSTRACT 1-MCP has been effectively used as an antagonist of ethylene deleterious actions in flowers and ornamental plants. The objective was to evaluate the efficiency of 1-MCP (0.0, 0.5, 1.0 and 1.5 g m-3) in maintaining post-production quality of exogenous ethylene sensitive ornamental pepper. Two commercial varieties were evaluated: Pimenta Colorida and Pimentão Ornamental, both Capsicum annuum. The pre-treatment with 1-MCP, regardless of the applied concentration, was effective in blocking the ethylene action reducing the leaves abscission, flowers and fruits of both genotypes by 100%. Plants pretreated with 1-MCP had postproduction life increased by eight and nine days for Pimenta Colorida and Pimentão Ornamental, respectively. The 1-MCP application... |

The objective of this work was to evaluate the adaptation of anthurium (Anthurium andraeanum) cultivars as cut flowers in a subtropical area, located in north of Paraná State, Brazil. The Apalai, Ianomami, Kinã, nK 102, Parakanã, Rubi, and Terena cultivars were cultivated in a nursery under 80% shade. The number of leaves and inflorescences, floral stem length, length and width of inflorescences, and spadix length were evaluated. The experimental design was in completely randomized blocks, with six replicates and five plants per plot. During the 18 months evaluated, 'Parakanã' produced 11 inflorescences per plant, whereas the other cultivars produced seven to nine inflorescences per plant. The number of leaves produced per plant was: 'Ianomami', 25;... |

Background: Calibrachoa Cerv. (ex La Llave & Lexarza) is a genus of the Solanaceae family (La Llave and Lexarza, 1825). This genus has a high ornamental and economic value due to its intrinsic variability and multiplicity of flower colours. In Argentina there are eight native species, and one of them is Calibrachoa caesia. The genetic diversity among 35 accessions of C. caesia, from five departments in the province of Misiones, was analyzed using ISSR markers. Results: Thirteen ISSR primers yielded a reproducible banding pattern, with 701 amplified loci and 98% of polymorphism. The ISSR primers 5CT, 5CA, 5GA, 5GACA, 3CAC, 3TG and 3TC generated 100% polymorphic patterns. The Rp values ranged from 23.20 to 10.29 for 5GACA and 3AG primers,... |

In 30 surveys across Cordoba city and surroundings (Argentina) I recorded, from November 2001 to May 2002, a total of 109 ornamental plants infested with aphid colonies. Surveys were conducted in the local botanical garden as well as homestead gardens and nurseries. Seventeen species of aphids were identified, 4 of which are new species in the area, from 47 ornamental plants. In a total of 59 plant/aphid associations, 38 new associations were found. I present the first record of aphids colonizing Cactaceae in Argentina. Most aphid colonies were medium and a high proportion (more than 40%) showed alate individuals. The most frequent aphid species, Aphis gossypii Glover and Aphis craccivora Koch were especially associated with the most frequent damages:... |

Succulents present great commercial importance, but information on the cultivation of these plants are not enough, especially considering the use of fertilizers during the growth phase. The objective of this study was to evaluate the effect of different fertilizers applied to the substrate in the cultivation of Kalanchoe luciae Raym.-Hamet. Cuttings measuring 6 cm in height and 12 cm in diameter were cultivated in 1.5 L pots containing the substrate (1 soil: 1 sand: 1 vermiculite). In this experiment, the effect of the fertilization based on NPK 10:10:10 was evaluated with and without the addition of a fertilizer mixture composed of 5 g bone flour, 5 g dolomite limestone, and 50 g ground charcoal, this proportion that was used for each 1.5 L substrate.... |

Bromeliads grow almost exclusively in the New World tropics and subtropics, mainly in South America in the Brazilian Atlantic Forest (ca. 1200 species). Within the last few decades, their beautiful shapes and colors, low maintenance and easy adaptability to small gardens have brought bromeliads into worldwide use as ornamental plants. While the ornamental bromeliad trade could make significant contributions to household economies in rural areas, the trade may represent a significant threat in some of the bromeliad biodiversity hotspot countries such as Brazil, Bolivia and Colombia. This paper presents an overview of production volumes, analysis of the Brazilian bromeliads trade chain – at the state, national and international levels – and recommendations... |

Está cada vez mais comum a valorização das plantas ornamentais nos centros urbanos, pois estas conferem sensação de bem-estar aos ambientes. As plantas ornamentais têm a função de transmitir harmonia, sensação de tranquilidade e conforto ao observador, contribuindo para o bem estar mental e físico (Silva et al., 2014). Contudo, apesar de embelezar o espaço, se escolhidas ao acaso, sem estudo prévio do possível impacto ambiental a ser gerado na área e da análise de suas características, não se levando em consideração seu local de origem, seu método de propagação e sua velocidade de eprodução, estas podem se tornar plantas daninhas (Gonçalves; Melo, 2013). Apesar da megadiversidade e participação em diversos programas de melhoramento genético no exterior, o... |

The post-production quality of ornamental peppers can be shorted due to exposure to ethylene. The concentration of this phytohormone at 10 µL/L induces leaf, fruit and flowers abscission, ripening of climacteric fruits, organ senescence, seed germination and seedling growth. We evaluated the correlation between pepper morphoagronomic traits and resistance to ethylene on ornamental peppers. Two genotypes, one resistant (UFPB 132), a susceptible (UFPB 134), and two hybrids (DR x PN) were utilized (76 x PN) to assess the susceptibility or resistance to ethylene. The experimental design was completely randomized, with four replications. First, 19 morphoagronomic characteristics were analyzed when the plants had 30% of fruits at the ripe stage. At this stage,... |

The influence of gibberellic acid (GA3) and water regime was evaluated in the flowering induction and quality of two orchid hybrids belonging to the genera Cattleya (C.) and Brassocattleya (Bc.). The experiment was carried out in the Biotechnology and Orchid Culture Sector of Shunji Nishimura Technology Foundation, Pompéia, São Paulo State, Brazil. Five GA3 concentrations (0, 125, 250, 500 and 1,000 mg L-1) were tested through four consecutive leaf applications in adult plants that had already flowered at least once, besides two water conditions (one and four irrigations per week). Applications were performed in October and November for Bc. Marcella Koss and in January and February for C. Irene Holguin. Flowering could not be induced in the latter by... |

Ornamental plants have been proposed for growing in heavy metal (HM) contaminated soils, and also for phytoremediation. We evaluated (1) biomass production and (2) HM accumulation in Pelargonium hortorum. Plants were grown for 16 weeks on HM (cadmium, chromium, copper, lead, nickel and zinc) enriched soils. Treatments were i) control, non-enriched soil, ii) medium concentration treatment, and iii) high concentration treatment. Four destructive harvests were carried out, and roots, stems, leaves, and flowers were analyzed each time. Concentrations of HM were determined using ICP. Significant reductions in biomass production were observed in HM-enriched soils compared with the control. Different indexes confirmed that P. hortorum was affected by HM. Heavy... |

(Hybridization among wild passionflower species). Passion fruits are appreciated for their ornamental value, since their flowers are showy and display a wide variety of colors. In addition, many hybrids have been produced and used in other countries. The genotypes used in selection of plants with ornamental characteristics are hybrid progenies which are used in various crossing strategies. Thus, the aim of this work was to obtain interspecific hybrids, perform backcrossing and obtain progenies from crossings between hybrids, and to determine the reproductive compatibility between the progenitors involved. The percentage of fertilized flowers, germination, and the number of fruits, seeds and plants obtained through crossing were recorded. A series of 374... |

The present work reports the effect of different pH and sucrose concentrations on in vitro propagation of Nephrolepis biserrata. Fronds aseptically obtained from stolon segment culture were cultivated in MS semi-solid medium supplemented with 0, 15, 30, 45 and 60g.L-1 sucrose and pH adjusted to 3, 5, 7 and 9, in a factorial design. Frond number and length, pinnae number, raquis length and diameter, fresh and dry matter weight were measured. Inhibition of shoot and leaf regeneration was observed in all the pH treatments in the absence of sucrose. On the other hand, when sucrose was added to the medium, the shoot number increased, reaching the maximum average values of 51.25 and 38.25 shoot per explant at pH 5 and 7, respectively. Sucrose concentrations from... |

ABSTRACT Within the genetic variability of the Capsicum genus there are plants with ornamental potential, but awry height required by the market. Paclobutrazol (PBZ), gibberellin retardant and growth inhibitor, is normally used as alternative to reduce plant height. The objective was to evaluate the PBZ (0, 25, 50 and 75 mg L-1) effect on plant height of eight pepper genotypes. Seven accessions [BGH 1032, BGH 1039, BGH 7073 (C. annuum), BGH 4285, BGH 4199, BGH 4355 and BGH 6371 (C. chinense)] of the germplasm bank from Universidade Federal de Viçosa and one access [MG 302 (C. annuum)] from the germplasm bank of the Empresa de Pesquisa Agropecuária de Minas Gerais were evaluated. The PBZ application was ineffective in altering plant architecture of BGH... |

ABSTRACT: Visual symptoms of Zn deficiency, induced by excessive P applications, have been observed in commercial orchid nurseries. The supply of other metallic micronutrients, such as Fe and Mn, may also be inadequate in the plant due to high application rates of P. The aim of this study was to investigate this interaction in the nutrition of Phalaenopsis plants. Experimental treatments consisted of three P rates (0.0, 0.5, and 1.0 g L-1) and three Zn rates (0.00, 0.35, and 0.70 g L-1), as well as fertilization with other basic nutrients, and a control treatment with the fertilizer B&G Orchidée(r), at 1.0 g L-1. Dry matter production was evaluated, as well as the levels of P, Zn, Fe, and Mn in both shoots and roots. Higher P rates induced higher shoot... |
