摘要
A ventilated leaf attachment clamp is described with which lateral air flow can be measured separately from through flow. Stomatal conductances are expressed with dimensions: mm s-1. Based on parallel measurements with a diffusion porometer the relation between mass flow and diffusive flow conductances has been experimentally determined for three species. Records of stomatal movements in air of different compositions are presented.
