RESCUE METHODS AND THE CHRONOLOGICAL AGES OF STOCK PLANTS ON EPICORMIC SHOOTS OF Ilex paraguariensis ROOTING

ABSTRACT

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).
