Concordância de testes de comparação de médias na avaliação volumétricas de clones de Eucalyptus spp. no Pólo Gesseiro do Araripe-PE

Abstract

When choosing the ideal test to perform the comparison of the experimental treatments means, there is no standard way or a manual or a solution to define the optimal test. The authors of each test set only a few theoretical restrictions or small details, but none of them determines to which experiment the test should be applied. As there is a need to establish which tests are best indicated and illustrate with an application it was used in this paper a design located in the region of the Gypsum Pole of the Araripe-PE with 15 clones of Eucalyptus spp. that were measured every six months over seven years, from 2002 to 2009,. In this paper, the tests used were the most widespread in the literature and applied the original methodologies in order to analyze the similarities among the tests at the levels of 1% and 5% of probabilities, and establish which clones presented mean of productions more significant. According to the results presented it was concluded that the tests of Tukey and Conagin are the most recommended and clones C41, C11 and C39 were the most productivies for biomass production in the region of Gypsum Plaster Pole of Araripe-PE.
