 This study found that pre-treating chrysanthemum cut flowers with ammonium sulfate, calcium nitrate, or potassium nitrate in varying concentrations can affect their post-harvest characteristics, including petal ion leakage, leaf SPAD values, carotenoids, water uptake, and shelf life. Ammonium sulfate at low to moderate concentrations improved shelf life, while high concentrations reduced it. Calcium nitrate and potassium nitrate significantly prolonged flower shelf life to 12 days compared to 6 days of control.
