| Popis: | Somatic embryogenesis offers a tremendous potential for the micropropagation of conifers with a relatively long reproduction cycle and low fructification frequency, and those in which traditional micropropagation by axillary budding is ineffective. The Norway spruce represents an excellent example of this. Moreover, the Norway spruce is one of the most abundant conifers in Northern and Central Europe whose population is endangered by pollution and insects in some areas. The multiplication of particular genotypes which have a higher degree of resistance to such unfavourable environments is of great current concern. The potential advantages of production of plants through somatic embryogenesis over cutting of plants derived from organogenesis in P. abies are an almost unlimited number of plants obtained from one donor plant within a short period of time, the possibility of cryopreservation of embryogenie cell lines, the future prospect of reducing labour and embling costs resulting from the fact that the technique is amenable to automation, and finally, the possibility of rejuvenating mature trees identified as elite genotypes by this method. |
