Abstract
Increased interest in tropical cut flower export in developing nations has increased the demand for clean planting stock.
The most popular items have been Strelitzia, various gingers (Alpinia) and Heliconia. This paper reviews seed and vegetative methods of propagation for each group.
Auxins such as IBA and NAA enhanced root development on aerial offshoots of Alpinia at the rate of 500 ppm while the cytokinin, PBA enhanced basal shoot development at 100 ppm.
Rhizomes of Heliconia survived treatment in 48°C hot water for periods up to 1 hour and 50°C up to 30 minutes in an experiment to determine their tolerance to temperatures for eradicating nematodes.
