In Vivo Date Palm

Abstract

Date palm (Phoenix dactylifera L.) plants demand reclamation of new areas or renewal of the oldest trees. Different methods to produce these plants as seeds that gave only 50% of seedlings will be female. The dates from seedling plants are often smaller and of poorer quality, so the propagation of date palm plantlets will occur with different methods. In vitro culture produced true-to-type huge numbers of plantlets under control conditions that led to many differences in morphology, physiology, and anatomy characteristics. The acclimatization was done to modify these abnormalities, and the plantlets after acclimatization need to improve growth by different treatments. Offshoots are the other method for propagation. These offshoots that grow from the base of the tree need to improve new rooting at the trunk base by growth regulators substances. This work shed light on the different methods of date palm propagation, the crucial role of the acclimatization greenhouse stage, and improved plantlets planted in the open field.
