Stillwater, OK: A new study by the University of Oklahoma researchers has explored the application of persistent luminescent powders on rose cut flowers, providing new insights into the interaction between floral materials and advanced luminescent technologies.
Rose cut flowers are popular in everyday bouquets or for special occasions, and value addition techniques, such as color tinting, contribute to economic growth in the floriculture market by increasing the flowers' value 5 to 10 times the original market value In this study, luminescence in red and white rose cut flowers was achieved by applying six persistent luminescent powders.
The research focuses on evaluating how various colors of these specialized powders enhance the aesthetic and functional properties of roses. Persistent luminescent powders, known for their ability to absorb and store light energy for extended periods, have gained significant attention for their potential applications in art, design, and horticulture.
The study investigated the visual and material compatibility of several powder colors on rose petals, aiming to determine the best combinations for vibrant, enduring effects. The findings highlight the role of color selection and powder formulation in achieving optimal results, emphasizing their practical applications in decorative arrangements, event planning, and innovative product designs.
It was found that, overall, white roses with green and blue powders are recommended over other powder treatments and red roses based upon luminescent qualities. The authors feel that future studies should provide a protocol to ensure consistent health among flowers and use other methods for correcting white balance, segmentation of black pixels, other color spaces, rates of application to increase luminescence of colored powders, and further analysis into the differentiation of mode and mean values.
This research opens the door for new creative and commercial uses of persistent luminescent powders in floral art, contributing to the broader integration of sustainable luminescent technologies in everyday life.

Established in 1903, the American Society for Horticultural Science is recognized around the world as one of the most respected and influential professional societies for horticultural scientists. ASHS is committed to promoting and encouraging national and international interest in scientific research and education in all branches of horticulture.
Comprised of thousands of members worldwide, ASHS represents a broad cross-section of the horticultural community - scientists, educators, students, landscape and turf managers, government, extension agents and industry professionals. ASHS members focus on practices and problems in horticulture: breeding, propagation, production and management, harvesting, handling and storage, processing, marketing and use of horticultural plants and products.
