The aim of this review is to critically assess and interpret the recent advancements in flowering regulation techniques applied in the cut flower industry, which is increasingly driven by market-oriented and off-season demands. The scope of this paper encompasses key physiological, chemical, environmental and genetic approaches to manipulate flowering, including photoperiod manipulation, plant growth regulators (PGRs), temperature regulation (vernalization and thermal treatments), mechanical methods like pinching and pruning, staggered planting and genotype selection. These technologies enable growers to produce high-quality blooms irrespective of natural flowering seasons, thus ensuring year-round availability, enhanced market value and resource optimization. Advanced applications such as the use of precision agriculture tools, genotype-specific flowering scheduling and bulb forcing techniques have revolutionized the floriculture industry by improving predictability and consistency in flower production. Integration of cold storage for bulbs (e.g., tulips, lilies) with specific light treatments has proven effective in synchronizing flowering. Similarly, growth retardants and ethylene modulators are used to tailor floral traits as per market preferences. Mechanical methods contribute to increased flower uniformity and quality by influencing hormonal pathways and branching behaviour. While these advancements have significantly improved economic returns and production efficiency, challenges remain in the form of environmental concerns, overuse of chemicals and variability in cultivar responses. The review concludes that future strategies must emphasize sustainable technologies, including the integration of molecular breeding and eco-friendly inputs. This synthesis serves as a comprehensive reference for researchers, horticulturists, and commercial growers aiming to modernize cut flower production through advanced flowering regulation practices.
