Abstract
ABSTRACT The present study was carried out with the objective of evaluating the field performance of six Eucalyptus clones, using seed-produced Eucalyptus urophylla as a reference. The experiment was conducted in the city of Vitoria da Conquista, Bahia, Brazil. The plants were monitored monthly with diameter at ground level and height measurements taken up to nine months after planting. Diameter at breast height (DBH) and height measurements, as well as the biomass of all tree components and stem volumes were obtained 12 months after planting. VM058 and I-144 were the only clones that showed survival rates below 70%. Nevertheless, up to the age of 12 months and similar to the seed-produced E. urophylla , the VM058 clone was the genetic material that presented the most satisfactory production given the edaphoclimatic conditions of Vitoria da Conquista, Bahia, Brazil.
Highlights
Faced with the growing demand for forest-based products, there has been an expansion of planted forest area in Brazil, which currently corresponds to about 7.8 million hectares (IBÁ, 2016)
Among the evaluated clones, only I-144 and VM058 would not be considered promising for the edaphoclimatic conditions of the study
In addition to survival rates, the selection and recommendation of adapted genetic material should take into account other aspects such as the growth and productivity of variables of interest (Azevedo et al, 2015; Frigotto, 2016)
Summary
Faced with the growing demand for forest-based products, there has been an expansion of planted forest area in Brazil, which currently corresponds to about 7.8 million hectares (IBÁ, 2016). The selection of species tolerant to drought is of fundamental importance for the success of forestry activities, considering that plant growth and development are affected by biotic and abiotic factors, such as temperature and soil water content (Fernandes, 2012). In this sense, genetic improvement programs carried out through techniques such as cloning have contributed considerably to the success of forestry enterprises in Brazil. A progressive increase in the area of clonal forest plantations under the most varied environmental conditions of the Brazilian territory can be observed (Xavier & Silva, 2010)
