Cooperative Program for Forest Enhancement

The forest improvement area is one of the major operation lines of the Institute, since its setup in April 1968. Currently, the area is divided into projects, out of which: Enhancement Center Populations (PCPN) which is gathering traditional materials and those already enhanced existing in the companies and in the national and international experimental stations; Enhancement Populations, which was proposed in 2011, and shall have its formal beginning in 2012, is aiming to work in the rescuing of materials existing in Brazil and the introduction of potential materials; and New Cultivations (PCNC) which aims to identify hybrid or pure clones of non-traditional species for multiple use in different Brazilian regions.

Other activities are also carried out at PCMF, and in 2011, the enhancement program was responsible for one of the IPEF international trips which had companies’ participants, universities and the institute itself, which had the possibility to meet INTA in Argentina and the companies Forestal Oriental, Montes Del Plata and Mundial Forestacion in Uruguay. A course of basic principles for application of the SELEGEN in tree species genetics was accomplished. Another activity carried out by PCMF was the process for import of seeds from Australia.

Main projects

Center Populations

The PCPN was created in 2008, aimed at gathering the enhanced genetic materials existing in the companies, in the experimental stations in Brazil and abroad, aimed at expanding the potential material base for the participant companies. Grouping and recombination of the selected individuals shall serve as a source of seedsand genetic material for the companies to enrich their enhancement programs. Another major factor is formation of an experimental network, in which shall be possible to be accomplish ecologic zoning of important species for the forest sector.

• Install populations with wide genetic base coming from the companies and the experimental stations;
• Provide material to the participant companies contributing towards expansion of the genetic base of their experimental populations;
• Implement tests in the companies for accomplishment of the ecologic zoning through analysis of the stability and adaptability of the progenies/originsin different regions; and
• Generate scientific works by means of basic researches with graduation and post-graduation students.

Enhancement Populations

The major goal is maintenance, expansion and availability of genetic materials for formation of the commercial plantations. This project is working in expansion of the genetic base available for the participant companies that may introduce materials in the enhancement programs, assisting in sustainability in the long term. It shall make easier for introgression of tolerance genes to the environmental stresses (due to occupation of newfrontiers orclimatic changes), to the new plagues and diseases, or even change to quality of the wood for several uses.

• Compose a broad genetic list by rescuing materials existing in Brazil and introducing materials coming from other countries. Such list shall be at the disposal of the companies which shall have access to seeds, pollen, propagule and clones of several species with genetic diversity;
• Meet the potential of some species without tradition in Brazil and that may be worked, in the future, in hybridization with the species traditionally used in the country or in new hybrid recombinations.

Such materials with less tradition shall be worked for obtaining the ecologic zoning in several edaphic and climatic conditions. For such specific study, a partnership shall be made with CSIRO and University of the Sunshine Coast researchers, which shall make possible for implementation of experiments in Brazil and Australia with the same genetic materials, the exchange of information and technical visits of experts from the different countries.

New Cultivations

It is currently common to use clones of pure or hybrid species in commercial planting of forest companies. These clones, commercially planted, call the attention of small- and medium-sized producers due to their productivity and homogeneity. These materials come from the genetic enhancement programs of forest companies or other research institutions which prioritize productive, raw materials, adapted to the determined weather and ground conditions and with qualities specific to their purpose, i.e., high quality raw material for their final product. However, these materials tend to specifically interest to the industrial process, because they have defined features and in most their cases do not meet the producers seeking to materials for multiple uses and also for other edaphic and climatic conditions.

This project is aimed at making genetic material of pure and hybrid species available for adaptation and development tests in several edaphic and climatic conditions. The most productive materials may be indicated for commercial plantations, aimed at small- and medium-sized producers.

Availability of the cultivations is made to those interested for test purpose.

The requirements for acquisition of the cultivations and implementation of the experimentsare: keeping nomenclature of the cultivations and provide inventory data of the tests. Change to the nomenclature makes it difficult to quantify the program results, because it prevents traceability of the approved materials and eventually used in commercial plantations. The inventory data shall be registered in a database for the purpose of structuring an experimental network of the materials generated.

• Generating cultivations to meet the demand by small- and medium-sized producers;
• Generating cultivations of non-traditional species for the enhancement practiced in the forest companies;
• Developing genetic material with capacity to multiple use;
• Offering clone material regionally tested, for trading of seedlings, to small-sized commercial farms;
• Optimizing use of the hybrid genetic resources available in the enhancement programs;
• Forming an experimental network of clone tests;
• Recommending genetic materials due to the result of local tests established;
• Quantifying and qualifying use of clone seedlings in view of the seminal seedling;
• Showing feasibility of the Eucalyptus cultivation in several regions;
• Implementing clone tests in zones with lack of information on Eucalyptus;
• Studying existing interactions between clone, site, nutrition and space; and,
Defining vegetative propagation protocol for non-traditional species.
