Conclusion 



1. As I have stated in the preceding parts, the general trend of 

 fluctuation for each factors of growth of a single tree and the aggregate, 



or stand may be interpreted by the equation y=ke in the particular 



cycle of the growth. However I cannot yet interpret the general trend of 

 the fluctuation as a continuous function with respect to throughout the 

 long life of the tree and the stand. This may be interpreted by the 



formula y=k(p(t)e and so there remains the study of ^(i). Further- 



more there is left for study the biological interpretation of the equation 



_A 



y=ke 



2. The development of diameter in stand interpreted by the formula 

 corresponding to the type I or IV in Pearson's skew curves. But in 

 nearest degree the frequency curve corresponds to the type V. 



The development of the corresponding height and volume of trees in 

 the stand with respect to the diameter interpretend by the formula: 



h=rJ^ — iWr, 



/ X 



and v=t\(^ — l)+r'2- 



In which the constants r, and r., r'l and r/ are functions of the age, and 

 each of them is expressed by the formula: 



A, 



y=Ke 

 in the given cycle of the growth.
