Résumé : Since Casuarinaccae appear to be an easy plant material to handle in vitro, two approaches are worth developing. The first approach is based on exploiting natural genetic variability. Casuarinaceae species were found to be easily micropropagated and culture of immature female inflorescences was developed for mature trees. Application of rapid in vitro propagation of elite #Casuarina# trees with improved saline or drought tolerance and a high ability to fix atmospheric nitrogen, would have a tremendous impact on the aflorestation of semiarid zones and would significantly improve forest productivity. The second approach is based on the application of gene transfer techniques to Casuarinas ( Phelep et al. 1991; Franche et al. 1994). Introduction of new traits such as herbicide and disease resistance, as well as modifications of wood quality, could be considered for Casuarina trees. Developing gene transfer systems for Casuarinaceae would also be of interest in the exploration of the establishment and functioning of the symbiosis between the actinorhizal trees and #Frankia# ( Franche et il. 1994).
