A computer-controlled vibration testing machine which creates a vibration-pattern conforming to an international norm for road transport, which can be compared with the real movements in a truck, was used to test the effects of different periods of time and different intensities of vibration on pot plants of Achimenes, Begonia, Beloperone, Browallia, Clerodendrum, Codiaeum, Dieffenbachia, Dizygotheca, Ficus benjamina, Hibiscus, New Guinea Impatiens, Kalanchoe, Radermachera, Saintpaulia, Schefflera, Schlumbergera, Sinningia and Streptocarpus. A dark period (before or after vibration treatments) was given to make plants more sensitive to stress conditions. Vibration caused severe damage to leaves and open flowers. Flower buds showed less damage. Much of the damage was caused by packing material, such as sustaining sticks and sleeves with sharp edges. Leaves of Kalanchoe were damaged by scouring along each other. Schefflera, Hibiscus and Clerodendrum showed necrotic spots on the leaves. After treat

ment for 2 days, >40% of the open flowers of Achimenes, Impatiens and Streptocarpus were damaged. To avoid direct visible mechanical damage, packing and transportation material should be improved. Vibration during transport had little long-term effect on keepability, indicating vibration has little effect on the physiological processes in plants. The loss of keepability caused by transport appeared to be more influenced by a dark period than by vibration. Data on damage after vibration treatment and long-term effects are tabulated for each species.
