Notes:
Summary A simple container is described whereby small seedlings may be grown at controlled levels of water stress. The water stress was induced in the soil by an osmoticum which is separated from the soil by a semi-permeable membrane. The mortality ofBetula pendula seedlings was markedly increased at a matric potential of −1.6 bars whereas the mortality ofBuddleia davidii was only affected below −2.8 bars. This difference in tolerance to water stress at the seedling stage might not be reflected in the distribution of the species in the colonisation of chalk and sand pits in England unless there is a dry spring.
