Anybody know how long roots can 'hold their breath'?
I would bet it is days, not minutes, especially in a bucket of 'fresh' (oxygenated) tap water.
Inside the tree, oxygen gets around by diffusion through the water in tissues. Oxygen gets into roots by diffusion through the film of water on the root surfaces. However, I don't have any idea what minimum required oxygenation level on the root surfaces to avoid anoxia. Anybody?
