GRAFTING TECHNIQUES AND THE USE OF ROOTSTOCKS IN LEUCADENDRON, AND OTHER PROTEACEOUS PLANTS

Breeding can be simplified if grafted plants are used, since the rootstock and the scion plants may be improved separately.

Proteaceae production under Israeli conditions is limited mainly by soil-root problems, namely: high pH of the soil, diseases and nematodes.
Grafted plants, using selected, resistant rootstocks can overcome these problems.
In addition grafting is being used as a method for vegetative propagation.

Grafting has been accomplished successfully and a large number of grafted Leucadendron plants have been produced.
It is somewhat more difficult, or useful, with other Proteas.

With Leucadendron the clonal L. coniferum selection L. "Orot" was tested.
As scions L. discolor and L. "Safari Sunset" was used. L. "Orot" seems to be a very suitable rootstock for the above scions under our conditions.
