Abstract
Flowering is a complex process which is regulated by several intricate external and internal factors that make its induction under in vitro culture highly sensitive. Recently, in vitro flowering has been extensively investigated for many plant species and significant advances in the understanding of this phenomenon have been made. However, with regard to date palm trees, this research area remains virtually unexplored. Accordingly, the present chapter aims to present some observations concerning in vitro flowering of date palm, and discusses the possible factors involved in the in vitro flowering induction of these plants. It also describes in vivo flowering in date palm and the limitations associated with its requirements. The chapter goes on to present the genes controlling the flowering process and to discuss the in vitro induction of bisexual flowers in date palm. The chapter concludes by discussing the importance of in vitro flowering to date palm propagation and its implications for future programs of early sex determination and genetic improvement via hybridization practices.
