A second pathway for gas out of the pressure chamber - what is being squeezed?
We report a qualitative description of the flows of gas that occur through a leaf when its balance pressure is measured in the pressure chamber. There are two distinct pathways: (a) a bulk flow of gas through the intercellular air spaces, and (b) a diffusion-driven pathway where gas is dissolved into solution under high pressure and comes out of solution at the liquid/atmosphere surface of the cut end where the pressure is atmospheric. The intercellular space flow is well known. It is argued...[Show more]
