Abstract: 

Due to the importance of Fagus orientalis in Iran which based on available statistics accounts per 17.5 of forest cover and 25 of standing volume of the North Iranian forest and is often utilized in the veneer manufacturing, this study was made to evaluate end checks variation between 30 Fagus orientalis logs after cutting, stocking and steaming which are greatly effective on the quality of the logs and finally on veneering efficiency. In addition the relationship of the end checks with the core diameter remained from the peeling process was carefully studied.
The findings of this study reveals that beech trees are very sensitive to the development of the end checks after cutting, stocking and steaming, besides it was concluded that the control of the logs in each of the above mentioned stages could reduce the end checks to a considerable extent and eventually cause the production efficiency to increase.
The increase in end checks number and their development after steaming had a significant effect on the increase of core diameter and led to production loss.
