PROPAGATION OF HEPTACODIUM MICONIOIDES, SEVEN SON FLOWER, BY SOFTWOOD AND SEMI-HARDWOOD CUTTINGS
Chin Chin Lee and T.E. Bilderback
Softwood and semi-hardwood two node cuttings of Heptacodium miconioides from basal and middlestem sections rooted better than terminal sections. Basal and middle softwood cuttings exhibited greater rooting (65 and 55%, respectively), than terminal cuttings (42 %). Basal softwood cuttings produced more roots (7 0) than terminal cuttings (3 8). Root length and rootball diameter were not different among the three cutting positions. Semi-hardwood basal cuttings produced an average of 53.5 roots while middle and terminal cuttings produced 25.8 and 19 7, respectively Cuttings treated with the potassium salt formulation of indolebutyric acid (K-IBA) exhibited increased rooting, greater root number and length, and greater rootball diameter in softwood cuttings. Semi-hardwood cuttings treated with K-IBA rooted in higher percentages and produced more roots than untreated cuttings.
