[Objective] The research aimed to study the response mechanism of plant stomata to formaldehyde pollution,to screen the indoor greenisation with high degrading efficiency to formaldehyde and to monitor formaldehyde pollution with plant.

[Method] Airtight reaction chamber method was used to investigate the effects of formaldehyde pollution on Vicia faba stomata reaction.

[Result] The length and width of two varieties of Vicia faba stomata were reduced with the increase of formaldehyde concentrations. No differences were discovered after 24 hours in Songzi green Vicia faba, though the stomata area was a little smaller than those of control (P0.05). However, after 48 hours, the stomata areas on Songzi green Vicia faba and common Vicia faba leaves were significantly smaller than those of control (P0.05).

[Conclusion] Common Vicia faba stomata was more sensitive to formaldehyde than that of Songzi green Vicia faba.
