| Abstract: | Objective: To explore the feasibility of preparing pollen samples for SEM by acetic anhydride. Methods: Acetic anhydride was used to treat pollinium before metal spraying. Then the prepared samples were observed under SEM. Results: After treatment, the interference of sticky substances on the surface of pollinium was removed, and the pollen grains were fully exposed, which was helpful to further observe their morphology. Conclusion: Using acetic anhydride to prepare pollinium sample provides a feasible idea to observe morphology of Dendrobium pollinium under SEM. |
