Abstract: This report details stowage and shipping procedures for exporting leatherleaf fern (Rumohra adiantiformis (G. Forst.) Ching) in van containers. Guidelines are recommended that will improve the arrival condition of fern in export markets. These recommendations were developed by studying product temperature profiles of 11 test loads in relation to thermostat settings of refrigeration units and loading patterns used to stow boxes in van containers. Recommended product temperatures for storing and shipping leatherleaf fern are 34°-40° F (1.1°-4.4° C) . When shipped in commercial van containers, it must be stowed in loading patterns that provide air channels through the load mass. Air channels allow free circulation of refrigerated air from the source of discharge to the return side of the refrigeration system. Discharge air temperature will fluctuate from the thermostat setting, especially during the first few days after loading. This is especially true when ferns are not precooled to recommended storage temperatures prior to loading in van containers. Thermostats must be properly calibrated to manufacturers' specifications prior to loading and set at 37° ± 1° F (2.8°± 0.6° C).
