Champereia manillana (Bl.) Merr. var. longistaminea is an evergreen small tree. It belongs to the genus Champereia Griff. (Opiliaceae), and its tender leaves or flower buds can be eaten. It also has important medicinal and nutritional values. Wild populations of C. manillana are small and has a phenomenon of deforestation. Market development is hindered by propagation constraints, including low seed germination rates and poor rooting of cuttings. Standardized cultivation protocols are currently lacking. This paper systematically reviews the current status of propagation and cultivation research on C. manillana and analyzed the primary challenges. Recent research indicated that seed germination obstacles had been preliminarily overcome, and 50% shading was identified as the optimal cultivation condition. However, challenges remain, including slow growth, lack of standardized water and fertilizer management, and unclear molecular mechanisms regulating development. Future research should focus on improving vegetative propagation efficiency, elucidating growth mechanisms via multi-omics, and establishing standardized cultivation protocols from breeding to harvest. These strategies are essential for the sustainable utilization of C. manillana resources.
