The effect of the stem disease caused by Peridermium pini (Pers.) Lev. on the water relations of Pinus sylvestris L. was investigated by comparing the permeability to water of wood from healthy and diseased stems. It was found that affected wood becomes impermeable and that severe infections cause complete loss of conducting ability in the stem. The impermeable wood is both resinous and dry; the importance of these features in causing the loss of permeability is discussed in relation to this and some other diseases.
