Abstract
Leucospermum High Gold (L. cordifolium × L. patersonii) can be propagated by cutting grafting.
To study the effect of wounding of the cuttings (two shallow and opposite incisions), rooting media (coconut fibre and a mixture of peat moss and polystyrene grains) and reduction of the foliar area of the scions on the rooting grafting process, an experiment was carried out in which scions of L. High Gold were wedge grafted onto unrooted cuttings of L. patersonii, which were subsequently rooted with bottom heat (22±2°C) under a fog system.
At 6 weeks from planting, the combination of scions with unreduced leaves + unwounded cuttings, rooted in peat moss-polystyrene grains gave 80% of grafted plants.
At that time, the mixture of peat moss and polystyrene grains gave a higher quality rooting than the coconut fibre.
At the end of the trial, at 16 weeks, all treatments showed grafted plant percentages higher than 70% success.
Wounding did not improve rooting.
Reduction of the foliar area of the scions did not improve the production of grafted plants.
