| Abstract:
Grevillea species are in different stages of development as flowering pot plants. In vitro propagation technique was used in order to achieve large scale production of six species and cultivars of Grevillea: G. ‘Roundo’, G. ‘Robyn’ Gordon', G. pinaster, G. crithmifolia, G. petrophiloides and G. ‘Robyn Hood’. The optimal 6-benzyl-aminopurine (BAP) level for shoot proliferation of two-nodal segments was 1 mg.l-1. Average propagation factor of all these Grevillea was 2.5 – 6.2 new axillary shoots in two months. The highest multiplication rate of 6.2 was in the case of G. crithmifolia as compared with only 2.5 in the case of G. petrophiloides. The highest percentage of in vitro rooting was achieved by 1 mg.l-1 NAA. | |
