Title

Preliminary Study of the Effect of Gamma Irradiation on the Vase Life of Iridaceae Hollandica

Abstract

The vase life of irises (Iridaceae Hollandica 'Telstar') was determined before and after gamma irradiation in the Missouri S&T Research Reactor (MSTR) at 20, 80, 457, 1060, and 1473 Gy. It was determined that vase life improves by as much as 7% for the 20 Gy irradiation. At about 100 Gy the vase life is comparable to non-irradiated flowers. Unfortunately pest control requires 200—300 Gy. At 457 Gy the vase life is about 15% shorter, and it gets worse at higher doses (30% lower vase life at 1 kGy). Gamma irradiation of irises can be a viable method of pest control, but the irradiation dose should be kept as low as possible while still achieving the phytosanitary objectives depending on the type of pest to control.
