GLADIOLUS SCABRIDUS - THE ROAD TO CONSERVATION AND COMMERCIALIZATION

Southern Africa has the richest temperate flora of any area of comparable size in the world. These diverse and interesting species form an integral part of our natural heritage, hence the importance and value placed on each one. Despite this resource, little has been done to realize the commercial potential. Many of these species have also been classified as endangered and their conservation is an important process. In southern Africa there are over 150 species of Gladioli. These popular and attractive flowers are commercially grown all over the world and many are hybrids which have been bred specifically, although a number of original species are grown commercially. Gladiolus scabridus is a vulnerable species with enormous commercial potential due to its unique floral characteristics. First named in 1978, it is endemic to the mountains of northern KwaZulu-Natal and southern Swaziland and is restricted to well-drained, rocky habitats. The large, bright pink flowers would make an attractive cut flower to satisfy ever-increasing consumer demand for new products. As little is known about its growth requirements, nutrient, water requirements and rapid propagation studies were conducted. Although originating from a stressful environment, they appear to show capacities for improved growth under controlled conditions. Successful tissue culture protocol has been established, as have norms for postharvest handling. This information together with knowledge of its ecology will allow for the promotion of its commercial production as well as aid the enhancement of its conservation status.
