Genetic variability of Araucaria angustifolia Bertol. initial growth: subsidy t...
Gerber, Dionatan; Brun, Eleandro José; Topanotti, Larissa Regina; Ferreira, Josângela de Jesus; Porrua, Douglas; Gorenstein, Maurício RomeroThe species Araucaria angustifolia Bertol. is native from Brazil, and it is now an endangered species due to the anthropic actions for several years. The objective of this study was to evaluate the genetic variability of Araucaria angustifolia based on initial growth qualitative and quantitative variables in a provenance and progeny test. Based on this performance, the genotypes with higher presence of superior...
Performance of Guazuma ulmifolia Lam. in subtropical forest restoration
Gerber, Dionatan; Topanotti, Larissa Regina; Gorenstein, Maurício Romero; Vieira, Frederico Márcio Corrêa; Stolarski, Oiliam CarlosWe evaluated the initial development of Guazuma ulmifolia Lam. in a reforestation experiment in the southwestern region of Parana State, Southern Brazil. In a 70 native tree species plantation (3x2 m spacing) data were collected biannually, up to 48 months, from 72 individuals of Guazuma ulmifolia. The species performance was evaluated regarding its survival (96%), root collar diameter (6.79 cm), total height (...
Initial growth performance of valuable timber species in southern Brazil: Arauc...
Topanotti, Larissa Regina; Gerber, Dionatan; Stolarski, Oiliam Carlos; Trentin, Bruna Elisa; Pertille, Carla Talita; Schorr, Luís Paulo BaldisseraThe initial growth of three Brazilian native timber species in the city of Dois Vizinhos-PR, Brazil, was described - Araucaria angustifolia, Balfourodendron riedelianum, and Parapiptadenia rigida, using four non-linear mathematical models (Gompertz, Logistic, Logistic 4P, and Chapman-Richards). In the fi rst 4 years after planting, information about collar diameter (mm), total height (m), crown height (m), and ...
Effect of the age on them stem form of Araucaria angustifolia in Central-Southe...
Martins, Ana Paula Marques; Machado, Sebastião do Amaral; Figueiredo Filho, Afonso; Corte, Ana Paula Dalla; Gorenstein, Maurício RomeroThe evolution of the stem form of trees in stands of Araucaria angustifolia (Bertol.) Kuntze was studied by means of taper functions and form factors. The data used were obtained by complete stem analysis and by rigorous scaling of standing trees in stands established in central-southern region of Paraná, with a sample of 45 trees. Four taper functions were adjusted for the total data set and for stratified dat...
Tree vegetation in an urban remnant: Lago da Paz forest, Dois Vizinhos, PR, Brazil
Konig Brun, Flávia Gizele; Brun, Eleandro José; Longhi, Solon Jonas; Gorenstein, Maurício Romero; Maria, Tamara Ribeiro Botelho CarvallhoThis study had the objective to analyze the floristic, structure and diversity of regeneration of a forest fragment located in the urban area of Dois Vizinhos, Paraná State. We used the census method and the traditional phytosociological descriptors as parameters of analysis, giving indications about the ecological value of the fragment. The results showed the occurrence of 231 individuals in 2,500 m² area, dis...
