Blue Phosphorescence of Standard Cut Flower Carnation

An experiment was conducted to quantify luminescence of white cut flower carnations after exposure blue glow-in-the-dark powder. Powder applied the flowers as either dip (3, 6, or 9 g) spray solutions in 240 mL water for 4 seconds plus a control. Stem fresh weight, relative stem diameter, and overall solution absorption were greatest on day 4. Only 6-g had greater average quality ratings than control, indicating reduced vase life, but there no difference among powder treatments. Phosphorescence is possible with fluorescent light, ultraviolet light increased mean brightness an 75% across all No treatment differences observed except 9; however, rates without general resulted brightness.
