摘要
The resin casting method has been applied to studying the inner wall structure of tracheids in normal and compression wood, Taxus chinensis in gymnosperm. Not only the structures which are visible by the conventional method, but also the three-dimensional structures of pits pair in intertracheids unvisualized by the normal way have been observed. Moreover, it is found that there exist many differences in the angle, trend and occurrence of helical thickenings and distribution of warty layers on the inner walls of tracheids in normal and compression wood.
