Rhizomes of Iris species used for perfume production do not contain scented irones immediately after harvest, precluding early selection of potentially high-producing genotypes. A recently developed technique involving a bacterial treatment (Rahnella aquatilis Izard, Gavini, Trinel, and Leclerc) of fresh rhizomes shortened the maturation time from 3 years to a few days. Variability in irone content among freshly harvested Iris species (76 clones) was evaluated, and three high-producing clones of Iris pallida Lam. were selected. Significant variability among clones was observed for irone content, growth, and yield.
