Density mini-stumps on mini-clonal hedge in the production of clonal seedlings eucalyptus PFB - Pesquisa Florestal Brasileira
Souza, Cibele Chaves; Xavier, Aloisio; Leite, Fernando Palha; Santana, Reynaldo Campos; Paiva, Haroldo Nogueira de.
The objective of this work was to evaluate different densities of rootedproductivity and survival as well as the effects on production and survival of cuttings produced. We performed two separate experiments, one for each genetic material (C1 and C2) and were assessed three densities for clone C1 (88, 75 and 57 ministumps m-2) and two for clone C2 (104 and 78 ministumps m-2). Shoots we collected from the ministumps and they were used in making cuttings 6-10 cm long. Sampling was initiated in January 2011, ending in March 2011. The cuttings were planted in substrate composed of 50% vermiculite and 50% of rice hulls and subsequently they were conducted in following steps: greenhouse, shade house and field hardening. For both clones, the density with smaller...

Evaluation of the spatial dependence of dendrometric characteristics for an Eucalyptus plantation Agronomy
Souza, Rodolfo Marcondes Silva; Almeida, André Quintão de; Ribeiro, Aristides; Souza, Eduardo Soares de; Leite, Fernando Palha.
Geostatistics evaluates the spatial dependence between two or more variables in order to estimate unknown values in space. The objective of this study was to evaluate, using geostatistical techniques, the spatial variability of dendrometric characteristics for a commercial plantation of Eucalyptus grandis x Eucalyptus urophylla located  in eastern Minas Gerais, Brazil (19º28’ S and 42º49’ W). The diameter at breast height (DBH) and commercial height (H) of 60 trees was measured in a forest inventory plot at two, five and seven years old. The volume of each tree in the plot was estimated from allometric equations and values of DBH and H. Spatial dependence of the three dendrometric variables at different ages was evaluated by fitting the experimental...
