Contribution of Pseudobombax aff. petropolitanum to Nutrient Cycling in Woody V...
Freitas,Carlos Antônio Araújo de; Souza,Rodrigo Camara de; Pereira,Marcos Gervasio; Caldeira,Marcos Vinicius Winckler; Couto,Dayvid RodriguesAbstract The aim of the study was to investigate Pseudobombax aff. petropolitanum (PP) contribution on annual fine litterfall, carbon content, and nutrient concentration, compared to other woody species (OS) on a neotropical inselberg in Espírito Santo state, Brazil. Annual fine litterfall was systematic monthly collected (November 2011-October 2012) by means of 15 littertraps (0.25 m2) placed in five transects...
CONTROLLED RELEASE FERTILIZER IN THE ROOTING AND PERFORMANCE OF CLONES OF Parat...
Araújo,Emanuel França; Gonçalves,Elzimar de Oliveira; Santos,Aline Ramalho dos; Gibson,Elbya Leão; Caldeira,Marcos Vinicius WincklerABSTRACT Paratecoma peroba is a native forest species of great economic and ecological interest, currently at risk of extinction. In addition to the difficulty of finding adult individuals of this species, plant production is limited, so the use of mini-cuttings can facilitate the spread of P. peroba. Thus, the objective of this study was to analyse the effect of different doses of controlled release fertilizer...
DISINFECTION PROTOCOL AND IN VITRO GERMINATION OF SEEDS OF Dalbergia nigra
Santos,Maricélia Moreira dos; Cezario,Luis Filipe Cabral; Simões,Ingridh Medeiros; Baptista,Julcinara Oliveira; Araujo,Caroline Palacio deABSTRACT The Atlantic Forest is a biome that has suffered anthropic actions, such as the extraction of hardwood, which can lead to the extinction of endemic species of great economic and ecological value, such as Dalbergia nigra. In this perspective, large-scale multiplication studies are necessary to contribute to the conservation of this species. The objective of this work was to establish a protocol for the ...
MINI-CUTTINGS TECHNIQUE FOR VEGETATIVE PROPAGATION OF Dalbergia nigra
Santos,Aline Ramalho dos; Gonçalves,Elzimar de Oliveira; Gibson,Elbya Leão; Araújo,Emanuel França; Wendling,Ivar; Tertuliano,Lara ArêasABSTRACT The usual propagation method for Dalbergia nigra is via seedings; however, the seasonal supply has a variable quantity of seeds which limits the continuous production of seedlings. Therefore, the objective of this study was to establish a vegetative propagation protocol via mini-cuttings technique for D. nigra from juvenile shoots obtained from seedlings. The experimental design was completely randomiz...
EVALUATION OF DIVERSITY AND GENETIC STRUCTURE AS STRATEGIES FOR CONSERVATION OF...
Silva Júnior,Adelson Lemes da; Cabral,Rafael Lara Rezende; Sartori,Lara; Souza,Lucimara Cruz de; Miranda,Fábio Demolinari deABSTRACT: The evaluation of diversity and genetic structure allows us to verify with precision the effect of evolutionary and anthropic processes on species. The objective of this research was to evaluate the divergence and the genetic structure of two natural populations of Dalbergia nigra, using molecular markers Inter Simple Sequence Repeats (ISSR). Leaf samples were collected from two populations, located i...
ECONOMIC AND OPERATIONAL ANALYSIS OF MECHANIZED FOREST IMPLEMENTATION
Fiedler,Nilton Cesar; Campos,Alexandre Arantes de; Caldeira,Marcos Vinicius Winckler; Lima,Julião Soares de Souza; Ramalho,Antônio Henrique CordeiroABSTRACT Mechanization in forestry implantation demands high energy, time, and high operational and production costs. Thus, studies related to the influence of variables on the efficiency of these activities are essential to reduce costs and optimize operations. The objective of this study was to evaluate the operational and cost performance of mechanized forest implantation operations in Eucalyptus sp. Data we...
Initial Growth of Pinus taeda by Fertilization Response at Planting
Trazzi,Paulo André; Santos,Juscelina Arcanjo dos; Caldeira,Marcos Vinicius Winckler; Roters,Diego Fernando; Carvalho,Dulcineia; Dobner Júnior,MárioABSTRACT The objective of this study was to evaluate how the fertilizer composition, type and application method contribute to the initial growth of Pinus taeda applied at planting. Seedlings from an open-pollinated seed orchard of Pinus taeda were planted on a Humic Dystrudepts soil containing 15 treatments of fertilizer application at planting. Basal diameter (immediately above ground – about 5 cm) and total ...
Decomposition of Leaf Litter in Semideciduous Submontane Forest, in The Souther...
Gomes Júnior,Diêgo; Caldeira,Marcos Vinicius Winckler; Klippel,Valéria Hollunder; Mendonça,Eduardo De Sá; Delarmelina,William MacedoABSTRACT The objective of this work was to understand the relationship between decomposition of leaf litter and climatic elements and determine the mineralization of nutrients in the decomposition process in a fragment of Semideciduous Submontane Forest, located in southern state of of Espírito Santo. Overall, 84 litterbags were deposited in 12 permanent plots, collecting one litterbag per plot for 30, 60, 90, ...
Litter as an Ecological Indicator of Forest Restoration Processes in a Dense Om...
Caldeira,Marcos Vinicius Winckler; Godinho,Tiago de Oliveira; Moreira,Fagner Luciano; Campanharo,Ítalo Favoreto; Castro,Kallil ChavesABSTRACT The objective of the present study was to evaluate the influence of spacing, species richness, and sampling time on accumulated litter in forest restoration areas in the state of Espírito Santo, Brazil. The experiment was conducted under a randomized complete block design, in a subdivided plot scheme. Six treatments were evaluated, consisting of a combination of spacing levels and species richness. Acc...
Controlled-Release Fertilizer on Growth of Melanoxylon brauna Schott Seedlings
Gibson,Elbya Leão; Gonçalves,Elzimar de Oliveira; Santos,Aline Ramalho Dos; Araújo,Emanuel França; Caldeira,Marcos Vinicius WincklerABSTRACT Melanoxylon brauna is a tree species native to the Atlantic Forest of high ecological and economic value. The objective of this study was to evaluate the growth and nutritional status of seedlings of two Melanoxylon brauna cultivars grown in substrate with different controlled-release fertilizer doses (CRF). The experiment was arranged in a randomized block 4 × 2 factorial design, with four CRF doses (...
