Abstract
The cultivation of South African proteas was introduced in the Canary Islands in the 1980s.
Farms grow, essentially, different cultivars of the genus Leucospermum, among them High Gold and Succession II . Most of Leucospermum species do not grow properly in clay soils, but grafting on a clay-soil resistant rootstock coul provide better performances.
The growth and yield of flowers of the cultivars mentioned above cultivated in clay soil was evaluated planting them directly or grafting on Leucospermum patersonii rootstock.
The assay consisted of four treatments, T1 = High Gold planted directly, T2 = grafted High Gold, T3 = Succession II planted directly, and T4 = grafted Succession II. The experiment was carried out over three years, following a randomized block design with four replications per treatment.
Grafting of High Gold on Leucospermum patersonii did not improve either the growth or the production of flowers, so it is not considered necessary in clay soil.
However, Succession II grafting on the same rootstock allowed plants to develop properly in clay soil, providing good flower production, compared to ungrafted plants, many of which died in the third year of cultivation.
