Summary

Flowering stems of Helichrysum diosmifolium, an Australian wild flower commonly called rice or sago flower, are exported to Japan. Flowering stems of both the broad-and fine-leaved forms were either precooled or not precooled. Leaf drop occurring 10, 12 and 14 days after harvest from flowering stems of both forms was reduced by silver thiosulphate pulsing. The most severe leaf drop occurred when flowering stems were not precooled and were kept dry until the assessment stage of the experiment. Severe leaf drop occurred 10, 12 and 14 days after harvest in flowering stems that were kept in water during precooling. The fine-leaved form had its longest vase life when it was precooled and the stems kept dry during this treatment. However, for the broad-leaved form, the longest vase life was obtained by pulsing stems with silver thiosulphate, followed by precooling with stems kept in water.
