ROOTING OF MICROCUTTINGS : GEENERAL ASPECTS |
| Author: | Ch. Moncousin |
| Abstract:
Horticultural industry is largely dependant on adventitious rooting whether it be with classical multiplication methods or with in vitro micropropagation. Hence it is surprising to see that interest for work on adventitious rhizogenesis has declined over the last ten years, whereas it should be of great economical importance due to the development of in vitro microcutting techniques. Scientifically speaking, adventitious rooting represents a model whose study is likely to bring essential information for the understanding of the mechanisms involved in organogenesis in plants. The reconstitution of the rooting system requires deep modifications in the metabolism of the cutting : assuming a similar rooting ontogenesis for the majority of cuttings without preformed roots, these cuttings will not all be able to form a new rooting system. | |
