Abstract
In the development of pine wilting disease caused by Bursaphelenchus lignicolus, water status in pines plays an important role in the pinenematode relationship. Levelling off in transpiration causes a population growth of nematodes in the wood. Such pines invariably wilt several weeks after the reduction of transpiration. The paper contains details of oleoresin exudation, transpiration and xylem water potential as well as the nematode population in the wood in connection with disease development.
