Effects of a mixed bed ion exchange resin column on vascular blockage and vase life were studied in cut roses (Rosa hybrida L. cv. Red American beauty) by measuring blockage rates in excised stem sections and by determining water uptake, fresh weight retention, and longevity of cut roses held in distilled water. The ion exchange column inhibited vascular blockage in excised stem segments. Water uptake and retention of fresh weight of cut roses were enhanced significantly by the ion exchange column treatment, and early wilting, known as “bent neck” was inhibited.
