| Abstract:
The New South Wales waratah is a woody proteaceous plant cultivated for cut flowers. Seed-raised plants vary in cut flower quality characteristics. A micropropagation method was developed to rapidly increase the number of plants of forms selected for cut flowers. After establishment in culture, single node explants initiated shoots on a modified MS medium. Shoots proliferated on a basal medium supplemented with IBA, BA and GA3, a six-fold increase being achieved in six weeks. Rooting was achieved both in, and out of culture. Precise control of temperature and humidity was essential for survival and the subsequent growth of the plantlets. The applicability of these techniques to Leucospermum and Leucadendron has been assessed. | |
