Validation of an automatic evaluation of sticky traps for fungus-gnats
Schuhli, Guilherme Schnell e; da Cruz, Pedro Cazetta; Franciscon, Luziane; Oliveira, Edilson Batista deThe evaluation of adhesive trap is a time-consuming task, vulnerable to count errors. Our proposition originated from the need to perform periodical evaluations of fungus-gnats (Diptera: Sciaridae). We selected, at random, 100 traps samples from a single site. Manual counting was performed and the traps were subsequently submitted to digitalization and automatic counting. We perform comparisons of both counting...
Brazilian National Forest Inventory – a landscape scale approach to monitoring ...
da Luz, Naíssa Batista; Garrastazu, Marilice Cordeiro; Rosot, Maria Augusta Doetzer; Maran, Jéssica Caroline; de Oliveira, Yeda Maria MalheirosThe strategic importance of forest resources, both at the national and global level, as well as the scarcity of reliable qualitative and quantitative information about Brazilian forests are among the motivations that led to the implementation of a new national forest inventory in Brazil (IFN-BR). Beyond traditional field survey through clustered sampling, the IFN-BR incorporates Landscape Sample Units (LSU) as ...
Callus induction in vitro on leaves explants of Ilex paraguariensis
Stachevski, Thamires Weigert; Franciscon, Luziane; Degenhardt-Goldbach, JulianaOrganogenesis is a technique rarely studied in the micro propagation of Ilex paraguariensis. This study evaluated different culture media on callus induction and in vitro organogenesis of this species. Leaves were collected from greenhouse grown plants. Leaves segments were placed on culture media ¼ MS, WPM or JADS, containing zeatin and 2,4-D. The MS medium was more efficient in callus inducing. Rooting was ob...
Calcium and potassium silicates and the growth of Eucalyptus grandis seedlings
Bognola, Itamar Antonio; Clasen, Lina Avila; Franciscon, Luziane; Gava, Jose Luiz; Dedecek, Renato Antonio; Silva, Fernando Márcio daThe use of silicate is a practice that has been frequently adopted in annual crops, although few studies have been conducted in order to verify its efficiency in forest tree species. The main objective of this research was to evaluate the effect of calcium and potassium silicates in the growth of seedlings of Eucalyptus grandis. The experiment was conducted in a greenhouse, in Alambari county, State of São Paul...
Site evaluation and productivity of a 3-year old stand of Eucalyptus urograndis...
Andrade, Guilherme de Castro; Bognola, Itamar Antonio; Bellote, Antonio Francisco Jurado; Franciscon, Luziane; Waterloo, Maarten JohannesPlantation forests in Brazil cover 7 million hectares, which represents 1% of the country (68% of Eucalyptus and 25% of Pinus plantations). The aim of this study was to evaluate a Eucalyptus urograndis plantation. High levels of Ca and Mg in the soil suggest that limestone had leached into the soil profile. The soil resistance down to 60 cm depth in the row of planting was lower than the inter-row space, indica...
ESTIMATING BLACK GLOBE TEMPERATURE FROM THE DRY BULB TEMPERATURE
Abreu, Paulo Giovanni de; Abreu, Valéria Maria Nascimento; Franciscon, Luziane; Coldebella, Arlei; Amaral, Adriana Garcia doOne disadvantage of bioclimatic diagnosis in certain region is non-availability of black globe temperatures (BGT) in the meteorological stations situated in different parts of the country. This study was done to propose a equation to estimate BGT from the dry bulb temperature (DBT), in confined and outdoors systems. Data of BGT and DBT were collected from inside and outside poultry sheds and analyzed using regr...
In vitro Establishment of Ocotea odorifera, O. catharinensis and O. porosa
Moritz, Aline; Degenhardt, Juliana; Dutra, Leonardo Ferreira; Hansel, Fabrício Augusto; Lima, Bruno Henrique de; Franceschi, Cristina do Rosário BatistaSeveral species of the Lauraceae family are endangered, due to the high value of their woods,and the consequent exploitation of natural populations. Among them, Ocotea porosa, O. odorifera and O.catharinensis, native from South Brazil, have recalcitrant seeds, what makes even more dificult their naturalregeneration. This work aimed to evaluate in vitro seed germination and multiplication of O. odorifera and O.c...
Evaluation of in natura heart palm quality from two peach palm populations duri...
Kalil, Geovanita Paulino da Costa; Kalil Filho, Antonio Nascim; Franciscon, LuzianePhysic-chemical parameters were used to evaluate the quality of fresh palm hearts of palm in the breeding program for quality of material produced. We monitored the pH, acidity (TA) and soluble solids (SS) of palm fresh during storage under refrigeration of the two most important populations of peach palm cultivated in Brazil. Were analyzed for microbiological and significant differences between the populations...
