Abstract
Abstract Giant miscanthus was successfully propagated with 1 or 2-node basal stem cuttings in July and 2-node basal stem cuttings in September. Upper single nodes, especially those 3rd and 4th most distal from the crown, rooted very poorly. There were no consistent differences among peat, perlite, peat: perlite and vermiculite media; however, in July 2007, cuttings in peat: perlite had significantly higher root dry weights than those in other media; and in July 2006, both peat and peat: perlite had significantly higher dry weights than did vermiculite or perlite. Single-node cuttings produced a higher proportion of plants, but 2-node cuttings had significantly more roots, longer roots and higher dry weights. Two-node September cuttings showed a higher percentage of rooting from the upper nodes than did July cuttings of either size. Although 2-node cuttings require larger propagation space and more materials, they produce less waste and a larger finished product than do single-node cuttings.
