Growth of native tree species in the recovery of degraded area in the coast of ...

This 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...

Rooting of Brazilian coral as a function of cutting types and season of the year

Erythrina falcata Benth. may be used as an ornamental plant, in rehabilitation of degraded land and as a component in agroforestry systems. However seedling production from seeds is difficult. The aim of this work was to evaluate vegetative propagation of E. falcata by using stem cuttings obtained from adult trees (softwood cuttings, hardwood cuttings and regrowth cuttings) and cuttings from seedlings collected...

Renewable substrates in the production of Ficus enormis seedlings from clonal g...

We aimed to assess the use of renewable substrates based on carbonized rice husk (CAC) and coconut fiber (FC) in the production of Ficus enormis Mart. ex Miq. seedlings through cutting stem from plants of clonal garden. We evaluated six substrates: commercial (control), composed of composted carbonized rice husks (CAC), coconut fiber (FC) and vermiculite (S1); 100% FC (S2); 100% CAC (S3); 50% FC and 50% CAC (S4...

Silvicultural evaluation of Rapanea ferruginea and Citharexylum myrianthum esta...

Planting 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...

Floristic composition and distribution of soil seed bank in Subtropical Ombroph...

In this research it was evaluated the potential of the soil seed bank in a remaining of Subtropical Ombrophilous Alluvial Forest (Araucaria Forest), by quali-quantitative analysis of seed germination. Additionally it was tested the occurrence of seasonal variation of the soil seed bank. The forest remaining located in Araucaria county, Parana State, Brazil, and it is influenced by Barigui river, affluent of Igu...

Technology for Adequate Handling of Albizia hassleri Seeds

Albizia is an indigenous specie of estacional forest, with potential to ornamental , environmental and agroforestry systems uses. The trees of (Albizia hassleri (CHODAT) BURKAT) in adult stage can attain 35 meters of height and diameter of height of breast (DHB) of 80 centimeters. Another important characteristic of that specie is ability to fix atmospheric nitrogen. This work was conduced at Embrapa Florestas,...

Interactions Between Indolebutyric Acid, Uniconazol and Two Types of Growing Me...

Pau-de-leite (Sapium glandulatum (Vell.) Pax., Euphorbiaceae) is a native tree of several Brazilian biomes, with great interest for rehabilitation of  degraded ecosystems due to its rusticity and intense seed dispersal by birds. However, its sexual  propagation is difficult because the majority of the  flowers are male and the percentage of germination of  the seeds is very low. Considering the propagation diff...

Climatic zoning for grevilea (Grevillea robusta) for the State of Parana, Brazil

Grevilea (Grevillea robusta A. Cunn) is a tree species from Australia and was introduced in Brazil in the late 19Th century. New progenies were imported and tested by Embrapa Forestry since the 90s. Currently there is great interest in planting this species in Parana, but so far there is no edafoclimatic or climatic zoning for the species. The criteria that were defined restrictive and favorable to the plantati...

Phosphorus nutrition in the growth of Bauhinia forficata L. seedlings - DOI: 10...

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 r...
