| Abstract:
The vegetative propagation of the Canary Islands Palm is impossible by the usual techniques: with the difference of the date palm tree to which it is on a botanical aspect very closed, this palm tree does not produce offshoots. The interest to propagate by a vegetative technique this famous ornamental palm is to multiply genotypes, selected specially for Fusarium resistance and cold hardness. A research on the in vitro propagation of this palm has been carried on since 1989. Starting from the shoot tips of small plantlets of various different genotypes, the production of proliferating clusters has been obtained. Since 1991, this proliferation is well established with a propagation rate between two and three each six weeks. The rooting and the acclimation of few hundred explants have been successful. The results obtained could be exploited for the commercial production of selected palm clones. | |
