Abstract
Global demand for tropical flowers requires product quality and new standards for plant propagation. Sustainable production and marketing are out- standing challenges. The objective of this study was to identify propagation trends in heliconia as an emerging crop within the global floriculture industry. To this end, a systematic search was conducted in the Web of Science, and bibliometric and textual content analysis techniques were applied using VOSviewer® and Atlas.ti® Scientific Software GmbH, respectively. The global trend in floriculture propagation focuses on acclimatization, mul- tiplication, in vitro propagation, organogenesis, somatic embryogenesis, growth regulators, regeneration, callogenesis, protocorms, and Agrobacterium- mediated transformation. The Heliconiaceae family is an important floricultural crop in this sector. The Research publications in heliconia is recent and little explored (2000 to 2025). Twenty-two species of Heliconia spp. were identified. The propagation trend is plant biotechnology, which accounted for 53.03% of the total. The propagation protocols identified were direct organogenesis, somatic embryogenesis, and temporary immersion systems. The main countries conducting research in this sector are Mexico (23.1%), Cuba (19.2%), and Brazil (15.4%). Both innovations applicable to organic farming were identified: the use of coconut water for germination and explant growth as a substitute for mineral salts MS (Murashige and Skoog), and the use of coconut fiber as an acclimatization substrate. Tropical floriculture, with an emphasis on heliconia, requires research to develop more efficient and sustainable propagation methods
