MÉTODOS DE RESGATE E IDADES CRONOLÓGICAS DE PLANTAS-MATRIZES NO ENRAIZAMENTO DE BROTAÇÕES EPICÓRMICAS DE Ilex paraguariensis

We investigate the rooting of epicormic shoots from girdling and coppicing of adult mate trees with 17 and 80-years-old, in the winter and the summer. Cuttings were planted in boxes filled with vermiculite and carbonized rice hull 1:1 (v/v) and after 90 days in greenhouse rooting percentage, number of roots, average root length, survival, callus and mortality were evaluated. Cuttings from girdled trees with 17-years-old showed better rooting (88.7%), number (13.3) and average root length (3.3 cm)
