Abstract
The commercial cultivation of proteas was introduced in the Canaries in the eighties of last century.
At the beginning, several species of the genus Banksia, Leucadendron, Leucospermum and Serruria, were planted.
Currently, Leucospermum cultivars are the base of its cultivation.
Areas potentially suitable for cultivation have clayey or alkaline-clayey soils.
The use of tolerant rootstocks to this type of soils, such as Leucospermum patersonii, could allow their development in them.
To study the propagation by cutting grafting of cultivars Anouk, Raziya, Succession I, and Themba of Leucospermum an experiment was carried out in which scions of cultivars cited above were wedge grafted onto terminal cuttings of L. patersonii, which were rooted with bottom heat (22±2°C) under a fog system in a glasshouse, with 50% of reduction of natural light.
Twenty-five scions of each cultivar were grafted.
The total number of grafts was 100. At the end of the trial, the cultivar Anouk gave 64% of grafted plants, being significantly different to the rest of cultivars, which showed values below 25%. At that time, the Anouk rooting index was significantly different from that of Raziya, but not from those of the other cultivars.
