Effects of ammonium to nitrate ratio on vase life and stem strength of gerbera cut flowers

The postharvest quality of gerbera cut flowers a major floricultural commodity is largely limited by stem bending and abbreviated vase life. Although nitrogen form is a critical preharvest variable, the optimum ammonium‑to‑nitrate (NH₄⁺/NO₃⁻) ratio for extending postharvest longe...
