TITON, Miranda; XAVIER, Aloisio; REIS, Geraldo Gonçalves dos and OTONI, Wagner Campos. Efficiency of ministumps and microstumps of Eucalyptus grandis clones for minicutting and microcutting production. Rev. Árvore [online]. 2003, vol.27, n.5, pp. 619-625.

The objective of this work was to evaluate the efficiency of clonal gardens in the microcutting and minicutting techniques of four Eucalyptus grandis clones regarding the survival, vigor and productive capacity of the microstumps and ministumps in successive collections of microcuttings and minicuttings. The microstumps were obtained from rejuvenated tissue explants through subculture in vitro, and the ministumps by minicuttings derived from conventional rooted cuttings. The ministumps and microstumps of E. grandis exhibited similar performance, i.e., high survival rate, vigor and productive capacity of vegetative propagation material.
