Unopened iris flowers (Iris x hollandica cv. Blue Magic) are enclosed by green sheath leaves. Flowers are harvested when the tepal tips are just visible. Flower opening depends on elongation of the stem part between the tepals and the uppermost node, consisting of a small segment between the tepals and the ovary, the ovary, and the pedicel. Two days of dry storage at 20 degrees C and 60% RH resulted in failure of flower opening in cut stems subsequently placed in water. Elongation of the pedicel and ovary was inhibited both during water stress and after subsequent placement in water. Pulsing with gibberellic acid (GA,) prior to dry storage alleviated the effect of water stress by promoting pedicel elongation and flower opening. A pulse treatment with ethanol partially alleviated the effect of dry storage on flower opening. The inclusion of hydroxyquinoline citrate (HQC) in the vase solution also partially compensated the effect of dry storage.
