| The objective of this study was to evaluate the effects of temperature, substrate and pre-germinative treatments on T. triangulare seeds. Four temperatures (constant 20, 25, 30 °C and alternate 20-30 °C) and two types of seeding (on paper and between paper), with light, were evaluated. The pre-germinative treatments evaluated included: immersion in water (24 hours), immersion in 6% hypochlorite solution (1 hour), immersion in 0.2% potassium nitrate solution (24 hours), immersion in 0.05% gibberellin solution (24 hours) and the control (untreated seeds). The highest germination percentage was observed at the alternate temperatures of 20-30 ºC, but with no significant difference between the substrates at this temperature. Soaking seeds in KNO3 gave the... |

| ABSTRACT The aims of this study were to establish micropropagation for Chenopodium ambrosioides L. and analysis of volatile constituents in vitro as a function of different salt concentrations of MS medium and sucrose. The apical buds were established on MS medium added with 3% sucrose. The vegetative growth of nodal segments was tested in different salt concentrations of MS basic medium (0.25, 0.50, 1.00, 1.50, and 2.00) and of sucrose (5, 10, 20, 30, and 40 g L-1). Nodal and apical segments were tested in vertical and horizontal orientations. Different volumes of culture medium (20; 35, 50, 65, and 80 mL) were examined in the growth of nodal segments. Plants were acclimatized in three different substrates. The apical segments collected from matrices... |

| The high demand for plant material from Calendula officinalis in the production of herbal medicines and cosmetics, turns the technique of plant-tissue culture into one of the alternatives for the improvement of crops over a short period of time. A protocol for tissue culture was developed from segments of seedlings of C. officinalis, in order to improve the proliferation of shoots and roots. We used a Murashige and Skoog (MS½N) medium, reduced to half the concentrations of NH4NO3 and KNO3 to verify the effect of different types of explants (basal, intermediate, and apical), a medium containing beach sand as support instead of agar, and the effect of auxins and cytokinins (TDZ tidiazuron; BAP, 6-benzylaminopurine, IAA, indol-3-acetic acid, IBA,... |

| ABSTRACT This study developed a methodology for callus induction in leaf segments of B. verbascifolia and evaluated the bioactive phenolic compounds production. Leaf explants were cultured in MS medium with 30 g L-1 sucrose, solidified with 7 g L- 1 agar supplemented with 2,4-D (0; 4.52; 9.05; 18.10 µM) and BAP (0; 4.44; 8.88; 17.75 µM ) in the presence and absence of light. Forty-five days after inoculation we assessed the percentage of callus induction, color, consistency, fresh and dry matter, total phenols, flavonoids, tannins contents, and chromatographic profile by HPLC-DAD method. Callus induction occurred only in medium with growth regulators. Maximal induction (100%) was found in medium containing 2,4-D combined with BAP in the presence and... |

| Cyrtomon luridus (Boh.), a native insect of wild Solanaceae, has adapted to the medicinal plant Duboisia sp., introduced from Australia, causing damages up to 100% mortality. Microctonus sp. is the most important natural enemy of C. luridus and its potential for biological control was investigated in this work. This study was carried out in Arapongas, Paraná State, Brazil, from 1994 to 1996. Parasitism of C. luridus by Microctonus sp. was highest from February through June (maximum of 54% in May 1996), when the C. luridus adult population was decreasing. The female sex ratio of Microctonus sp. under natural conditions was 0.57 to 0.69, which was close to 1 male : 2 female. Production of males occurs parthenogetically (arrhenotoky). In the laboratory,... |

| Mandevilla velutina (Mart.) Woodson (Apocynaceae) is a medicinal plant species with antivenom properties, native from Brazilian Savanna regions (Cerrado), which due to overexploitation and habitat deforestation is in danger of extinction. As an initiative for conserving this endangered but economically important plant species, a micropropagation protocol was developed and genotypes were stored in the Germplasm Bank "Cerrado In vitro". For the in vitro propagation of M. velutina, nodal segments were inoculated on Murashige and Skoog (MS) medium supplemented with different concentrations of BA, Zeatin, 2ip, DTT and TDZ. Best multiplication ratio was achieved when to the medium 0.44 µM BA, ranging 1: 6.7, were added. Plantlets cultured on MS/2 medium... |

| Pothomorphe umbellata (L.) Miquel, is a medicinal species that belong to the Piperaceae family and commonly called "pariparoba" and "caapeba". It grows in regions rich in humus, humidity and under the shade of trees, which contribute for its best growth as it is considered a species sciophyte. The effect of shade on the yield and chemical composition of essential oil of Pothomorphe umbellata (Piperaceae) leaves was evaluated. Nine-month-old seedlings were planted in October 2002 and subjected to three shade levels (30%, 50%, 70%) and full sun; the experimental design was in randomized blocks, with four treatments and six replications, in split-plot in time scheme. Two harvests of aerial part were made (05/2003 and 05/2004). Essential oil was extracted by... |

| Assigning an economic value to a given environmental asset has helped conservation proposals, and valuing these assets at levels comparable to market rates facilitates the establishment of environmental policies. Thus, this research aimed to assess the value of the species Myracrodruon urundeuva Allemão, using the method of contingent valuation to determine the maximum willingness to pay of frequent visitors to the Caruaru Fair, located in northeastern Brazil. Our results show that most interviewees agreed to participate in proposals to support species conservation, although the average willingness to pay (WTP) was relatively low compared to other surveys conducted in Brazil. However, a significant number of the interviewees had exceptionally low monthly... |

| One of the greatest problems in the elaboration of forestation programs using native species is the lack of knowledge about seedling production. This study aimed to evaluate the growth of Bauhinia forficate seedlings submitted to phosphorus levels. Eleven-day-old seedlings were transplanted to small tubettes (110 cm3) with pinus bark and vermiculite substratum base. The experiment was conducted in an entirely randomized delineation, with six P treatments: T0-control (substratum without P addition), T1-50, T2-100, T3-150, T4-200 and T5-250 mg dm-3, with five replications and 20 seedlings per replication. After 60 days, the seedlings presented a 98.2% survival rate and good root formation. The height varied in function of P levels, with maximum production up... |
