Leucadendron: A Major Proteaceous Floricultural Crop

Genetic Resources and Domestication of Macadamia

“…& J.C. Wendl., Protea L., and Leucadendron R.Br., all of which are cultivated for their inflorescences (Harden 1990;Criley 1998;Sedgley 1998;Coetzee and Littlejohn 2001;Ben-Jaacov and Silber 2006).…”

Rooting Responses of Female and Male Cuttings of Leucadendron elimense E. Phillips subsp. elimense on the Type and Concentration of Auxin

“…Two hundred terminal cuttings were then planted into perforated transparent bags 125 × 190 mm, obtained from Packit 354, Voortrekker Road, Maitland, Cape Town, Western Cape, with a mix of an acidic, well-drained medium ____________________________________________________________________________________________________________________ consisting of coarse river sand (2 mm diameter), coco peat, and perlite (2 : 1 : 1). The cuttings were buried one-third deep in the substrate to ensure good aeration (Ben-Jaacov & Silber 2006;Brown & Duncan 2006;Reinten 2014). The plants were then placed on the hotbeds in the greenhouse and watered thoroughly.…”

“…IBA has been reported as the most popular auxin used for cuttings propagation with various degrees of success documented in Proteaceae. The concentration IBA of 2000 ppm (Faruchi et al 1997;Reinten 2014) was recommended for rooting of Leucadendron species, although most successful results for cone bushes were reported by Ben-Jaacov and Silber (2006) using 2000 ppm of IBA. This finding was later confirmed by Laubscher and Ndakidemi (2008b) with 1000 to 2000 ppm IBA as the most significant in rooting for L. laxum; however, they also confirmed that concentrations higher than 4000 ppm inhibit rooting of cuttings, which was confirmed in our experiment for female cuttings.…”

“…The crown cone bushes have ____________________________________________________________________________________________________________________ hairless seeds that bulge outward on one side and go inward on the other, they have a ridged perimeter (Rebelo 2001). The cone bracts are free from one another, and all species in this group release their seeds after five months of ripening (Ben-Jaacov & Silber 2006).…”

A new Paracoccus species from Palaearctic region (Hemiptera, Sternorrhyncha, Coccoidea, Pseudococcidae)

“…This is because: (i) Leucadendron is a recently introduced crop in Portugal which originated from Southern Africa (Liu et al, 2007) . However, mealybugs were included by Ben-Jaacov & Silber (2007) in the list of severe pest groups of proteaceous species in South Africa, although they did not state which species were involved. On the other hand, four mealybug species were listed as pests of Proteaceae in South Africa by Lubbe (2006), namely, Delottococcus quaesitus (Brain), Phenacoccus stelli, Planococcus citri and Pseudococcus calceolariae.…”
