Efeito da estaquia, miniestaquia, microestaquia e micropropaga??o no desempenho silvicultural de clones híbridos de Eucalyptus spp.

摘要

The objective of the present study was to evaluate the performance of four Eucalyptus spp. hybrid clones, propagated by cutting, micropopagation, microcutting and minicutting techniques. The study evaluated height and diameter growth characteristics, as well as the aerial biomass production, in a clonal test installed in two localities in the north of Minas Gerais State. According to the results, it can be concluded that the effects of propagation techniques did not result in expressive differences in height growth and DBH, at ages 4, 8, 16 and 24 months, for the studied clones. In relation to the aerial biomass, the results did not indicate a tendency for possible effects of the propagation techniques on clone silvicultural performance.
