| Abstract:
Difficult to root species, such as Syringa vulgaris hybrids, may now be rooted to a high percentage and can be grown on their own roots through tissue culture. However, rooting percentage depends on the propagation system in vitro. The shoot cluster system and the single node system were compared for their effects on propagation and rooting. The propagation by shoot clusters, using axillary branching, will increase the multiplication rate but will also significantly reduce the rooting potential. For rooting it appears preferable to multiply Syringa shoots by the single node system. The combination of the advantages of both systems is possible by making use of the high multiplication rates of the shoot cluster system, and by growing the shootlets for at least one subculture according to the single node system before rooting. Additionally, the use of in vitro propagated stockplants for conventional cuttings can be considered a decisive improvement over expensive mass propagation in vitro. | |
