Growth and temperature profile of a Douglas-fir tree

This thesis investigated the temperature and growth profile of one Douglas-fir tree. A series of thermocouples located at different heights and depths was connected to one multi-channeled recorder. Using systematic sampling, data were recorded for a period of two years. Temperatures were analyzed for one summer and one winter month.
Vertical distribution of the width of annual rings was analyzed for the period of the last 50 years for both earlywood and latewood as well as for total annual rings. Basic growth theories were outlined and the thesis suggests that none of these gives a completely satisfactory answer. Possible significance of temperature on the vertical growth distribution of annual rings was outlined. / Forestry, Faculty of / Graduate
