Dr Hannes de Lange
Hannes has been intimately involved in research for HGH Pharmaceuticals on Sceletium tortuosum cultivation. He has two doctorates; one awarded in agriculture (Univ. Pretoria) and another in botany (Univ. Stellenbosch). He was involved in research on citrus at the Citrus and Subtropical Fruit Research Institute in Nelspruit for nearly 20 years with the main projects on the initiation of easy peeler (naartje) cultivation in South Africa, pollination requirements, breeding and tissue culture. Highlights during this period were the establishment of a successful easy peeler branch in the local citrus industry and the development and application of an in vitro technique whereby viruses were eliminated from superior citrus cultivars; a prerequisite for the formation of the Citrus Super Plant Scheme which was subsequently formed. In 1982 he received the “Transvaal Agriculturist of the Year” award for the latter research. In 1986 he joined the National Botanical Institute at Kirstenbosch following an invitation to establish a tissue culture unit in this institute. This was successfully done and he then moved on to other projects in the NBI (later to become the SA Nat. Biodiversity Institute) until his retirement in 1999. Highlights during this period was the discovery that chemicals present in smoke from veld fires are responsible for germination of seeds of fynbos species; and the initiation of the honeybush tea industry of which Hannes is at present a honorary member. He has published more than 60 scientific papers in overseas and local journals. During the period at the NBI he received several awards – from the NBI: Jubileum Prize for Research, Dyer Prize for Research Excellence, Chairman’s Merit Award; from the Agricultural Research Council: Executive Management Award, and from the South African Journal of Botany: Compton prize for best publication in 1993. Since retirement from the NBI in 1999 and residing in Oudtshoorn in the Klein Karoo, he has, apart from HGH Pharmaceuticals, also contracts with three European cosmetic, food and pharmaceutical companies, doing research on agricultural aspects in the utilisation of the particular fynbos species involved.
