The sample tree used in this experiments is Pinus densiflora of 25 trees taken from the different age class of even-aged stands in the Oe Experimental Forest of kyoto Prefectural University. We obtained the following regression epuations concerning the standard contents and the total contents of celluloses in single tree related with each one of the factors such as d・b・h, tree height, stem volume and age of tree. 1.
