Mini-tunnel models influence the productivity of eucalyptus mini-stumps?

Mini-cutting is the most common commercially used clonal propagation method in Brazil. However, several environmental interferences can impact this process, hindering production of propagules. Mini-tunnel have been to overcome these difficulties, allowing for an increase productivity mini-stumps and rooting mini-cuttings. This study aimed evaluate effect mini-tunnel models on mini-stump two hybrid eucalyptus clones over seasons. The was conducted seedling nursery a forestry company located Alto Vale do Jequitinhonha, Minas Gerais, Three were used: 35 cm, 55 cm tubular, without cover (control) seasons (cold hot). total effective mini-cuttings evaluated levels chlorophyll A B, chlorophyll, height, leaf area, dry matter determined. Together, season use influenced both clones. Use resulted high productivity, especially cold period. Mini-cuttings produced during hot showed greater growth, matter, area than those collected season. mini-tunnels mini-gardens, as shown here by its overall positive influence genotypes.
