Because the rate of survival of tissue culture-derived date palm plantlets (vitroplants) in acclimatization stage is significantly low, this study was suggested in order to focus on the anatomical structures of roots and leaves of date palm vitroplants. The obtained data showed the complete absence of vascular elements in roots of some sorts (clones) of vitro plants; meanwhile in other clones, the vascular elements were found to be in early stages of development. Anatomical variations were also recorded in leaf topography and anatomy among different clones of vitro plants originated from the same explant and subjected to the same media regime. The recorded anatomical variations and the poor development of vascular elements and consequently poor connection and transportations of water, solute, mineral and gases within the vascular elements, may be involved in severe wilting of date palm vitroplants in acclimatization stage. Accordingly, it could be suggested that successful acclimatization of date palm vitroplants starts in rooting stage in vitro.
