Growth of native tree species in the recovery of degraded area in the coast of ...
Schaffer, Luiz Henrique; Mattar, Eduardo Abilhoa; Nakajima, Nelson Yoshihiro; Silva, Samuel Alves; Borges, Ricardo AguiarThis study aimed to evaluate the growth of species Senna multijuga, Myrsine coriaceae, Schizolobium parahyba var. parahyba, Inga edulis, I. marginata and Citharexylum myrianthum, in the recovery of an area degraded by livestock. The experiment was conducted in the Natural Reserve of Guaricica in Antonina, PR. Four treatments were tested with different densities of individuals of each species, each with three re...
Silvicultural evaluation of Rapanea ferruginea and Citharexylum myrianthum esta...
Silveira, Sabine Borges; Neves, Edinelson José Maciel; Carpanezzi, Antonio Aparecido; Britez, Ricardo MirandaPlanting woodlots for ecosystem restoration must be based on silvics and ecological features of the species. This paper deals with silvicultural performance of native Brazilian species Rapanea ferruginea (Ruiz & Pav.) Mez and Citharexylum myrianthum Cham. planted in abandoned pastures in Antonina, coast of Paraná state. Monospecific plots were 69 months old and situated on hill slope and alluvial plain, sha...
Ambrosia beetles as bioindicators of “neem decline” in Brazil
Penteado, Susete do Rocio Chiarello; Carpanezzi, Aparecido Antonio; Neves, Edinelson José Maciel; Santos, Álvaro Figueredo dosThis is the first record of the beetles attack (Curculionidae, Scolitinae) in neem plantations located in Brejinho de Nazaré, Tocantins, Brazil. The insects were observed on plants between 7 and 10 years old and were identified as Xylosandrus compactus (Eichhoff), Cryptocarenus diadematus Eggers, 1937 and Hypothenemus sp. Westwood, 1836. The attacked plants showed a growth rate considered low for the region, ha...
Genetic Gain for Wood Volume in Progeny Trial of Grevílea (Breeding Cycle 2) in...
Martins, Emerson Gonçalves; Neves, Edinelson José Maciel; Sturion, José Alfredo; Aoki, HideyoTwenty and twenty three seed provenances of Grevillea robusta A. Cunn. were imported from Australia, in 1993 and 1994, respectively, by Embrapa Florestas. This genetic germoplasm was utilized for starting a breeding program in the states of Paraná, São Paulo and Mato Grosso do Sul. In 2002, twenty eight genotypes were selected in the Presidente Castelo Branco-PR district whose seeds were utilized for the instal...
Second Generation Half-sib Progenies Wood Production of Grevillea in the Region...
Martins, Emerson Gonçalves; Neves, Edinelson José Maciel; Aoki, Hideyo; Martins, Kelly GeronazzoThe Grevillea robusta A. Cunn is utilized for coffee plantation shading, crops growing and pasture shading, apiculture, ornamentation and wind breaks. It is also used to produce sawn wood. One test of 28 second generation half-sib progenies was planted in Forestry Institute of São Paulo, with 20°03’S latitude and 48°54’W logitude geographic coordenates and 630m of altitude. The main objectives of this paper wer...
Genetic Gain for Wood Volume in Progeny Trial of Grevillea robusta Cunn (Breedi...
Martins, Emerson Gonçalves; Neves, Edinelson José Maciel; Sturion, José Alfredo; Duleba, NicoleTwenty and twenty three seed provenances of Grevillea robusta Cunn were imported from Australia, in 1993 and 1994 respectively, by Embrapa Florestas. This genetic germoplasm was utilized for starting a breeding program in the State of Paraná, São Paulo and Mato Grosso do Sul. Total surface occupied by Grevillea experiments managed by Embrapa Florestas reachs 27,13 ha, being provenance tests, embracing 11,22 ha,...
Pupunha Palm Heart Production from Different Plant Density
Neves, Edinelson José Maciel; Santos, Álvaro Figueredo dos; Lavoranti, Osmir José; Martins, Emerson GonçalvesThe coast region of Paraná State, Brazil, has a great potential for growing of pupunha trees aiming palm heart production due to climate conditions. There were around one million pupunha trees planted at small farmers area, totalizing about 200 ha, in this region by the end of 2004. This fact confirms the specie as a sustainable and economicaly viable alternative for small farmers as long as the natural stands ...
Second Generation of Grevillea: Wood Production in Londrina-PR Region
Martins, Emerson Gonçalves; Neves, Edinelson José Maciel; Duleba, Nicole; Domakoski, Bernardo SkrochGrevillea robusta Cunn is not only utilized for coffee plantation shading, ornamentation and wind breaks. It is also used in apiculture and different wood utilities. The purpose of this study was to identify genetically superior individuals for wood volume production in order to select material for future seed orchards in the Londrina region of Northern Paraná State, Brazil. The genetic material tested was 37 s...
Hypsipyla grandella in Mahogany (Swietenia macrophylla): Current Situation and ...
Lunz, Alexandre Mehl; Thomazini, Marcílio José Thomazini; Moraes, Maria Carolina Blassioli; Neves, Edinelson José Maciel; Batista, Telma Fátima CoelhoThe mahogany wood, Swietenia macrophylla King, is valued in the international trade market forits beauty and durability for noble uses like furniture and decoration. Any attempt of commercial plantation ofthis specie to diminish the pressure made by its selective exploration fail due to the incidence of the mahoganyshoot borer, Hypsipyla grandella (Zeller). Although some works have had relative success in prese...
Production of three cuttings of Bactris gasipaes for heart-of-palm under differ...
Neves, Edinelson José Maciel; Santos, Álvaro Figueredo dosThe present study was developed to characterize the chemical properties of the soil under peach palm (Bactris gasipaes) plantations at 24, 39 and 48 months old, and to quantify the heart-of-palm production on a local industrial scale (packaged in various forms in glass jars). The experiment was set up in two areas, located along the Alexandra-Matinhos Road (km 7 and km 10) near Paranaguá county, State of Paran...
