Abstract:

 Brazil is the second largest producer of pulp and eighth in paper production in the world, among the most used species, or Pinus taeda is a major highlight, especially in the production of pulp and kraft paper. Pinus taeda is a second most planted species in Brazil, especially in the colder regions of the country, where it has high rates of development, reaching a rate of over 30m³ / ha / year. The objective of this research work was to characterize ten Pinus taeda progenies, based on the characteristics of the basic specific mass and the dimensions of its fibers, having as main focus the use of these trees in the pulp and paper production. The study analyzed 28 trees of ten different 18 year old Pinus taeda progenies. These trees were collected in the municipality of Otacilio Costa, state of Santa Catarina. The progenies were analyzed based on the following properties, specific mass, length, inner diameter, outer diameter and wall thickness of the fibers, aggregating as fiber measurements, also used correlations among them, flexibility coefficient, wall fraction, index weakening and Runkel index. The main results obtained in this work were that the progenies, although growing under conditions equal to development, present significant differences between the analyzed variables. Fiber length were the most prominent in fiber measurements, exceeding the values referenced by up to two times, the other measurements, wall fraction, internal and external diameter, if equivalent to the values surveyed. The relationships determined between the measurements of the raw fibers show great importance in the progeny selection process, as well as the Pearson correlations applied to the measured variables, observing the behavior of the basic specific mass, which alone does not provide reliability in this work. However, when analyzed together with the other data, it makes the selection process reliable. The selection of Pinus taeda progenies using the properties of tracheids is possible, combining the basic specific mass and increasing the confidence in selection. The progenies that stood out the most were 12, 21, 74 and 112, these were selected because they have greater balance among the analyzed variables, being the number 112 the best among them because it has the largest basic specific mass, added to the other characteristics, provides greater benefits in pulp and paper production.
