Subject:
Chamaecyparis obtusa; bark; cambium; hyperplasia; stems; tracheids; trees; wood anatomy; Japan
Abstract:
... The stem hyperplasia called tokkuri-disease in Japan was observed on the lower part of stems of 25-29-year-old Chamaecyparis obtusa trees. The anatomy of the hyperplastic portions was characterised by rapid proliferation of the cambium, short and thin-walled tracheids, a large number of multiseriate rays, and thickened bark. The cambial activity in the hyperplastic portion was high in July and rem ...
