Detailed Explanation of Key Post-Harvest Handling Techniques for Dendrobium Orchids

1. Scientific name: Dendrobium spp.

2. Main characteristics of cut flowers: Very sensitive to ethylene; pollination of the flowers should be avoided, as it stimulates the production of large amounts of ethylene.

3. Harvest maturity stage: Cut when most of the flowers on the inflorescence have opened, with only a small number of flowers at the top of the inflorescence still in the bud stage.

4. Vase life: The vase life in water is about 14 days, and longer in preservative solution. The vase life of Dendrobium varies with the season.

5. Preservative treatment method: Use a preservative to extend vase life and reduce inflorescence bending. Dipping the base of the inflorescence in hot water for 30 seconds can extend the life of the cut flowers.

6. Storage and transport techniques

(1) The optimal storage and transport temperature is 10-13°C.

(2) Soaking the cut flowers in water for 10-15 minutes allows rapid rehydration.

(3) Insert the cut flower stems into test tubes containing holding solution, and secure the test tubes to the bottom of the packing box with adhesive tape to prevent movement during transport.

(4) Use storage and transport preservative gel.

7. Retailer and consumer handling methods

(1) Recut the base of the inflorescence stems, then top up the test tubes with freshly prepared preservative solution, and check regularly.

(2) Wrap the base of the Dendrobium stems used as corsages in moist cotton.

(3) Avoid exposing cut flowers to ethylene; keep them away from smoke, ripe fruit and wilted flowers.

(4) The optimal storage temperature is 10-13°C. Avoid excessively hot or cold temperatures.
