Abstract
Sclerosed and pitted tyloses were discovered in the springwood tracheids of Taxodium distichum Rich stemwood which has taxodioid or cupressoid cross field pits, and these tyloses were believed to be caused by protrusion of enlarged ray parenchyma cells into tracheid lumina.
단막공(單膜孔)을 지니는 후막(厚膜)의 타일로시스가 삼나무형(型) 또는 편백형(型) 분야막공(分野膜孔)을 나타내는 낙우송(落羽松)의 수간(樹幹) 춘재(春材) 가도관(假導管)에서 관찰(觀察)되었으며 이러한 타일로시스는 방사유세포(放射柔細胞)가 가도관내강(假導管內腔)내로 확대(擴大) 침입(侵入)됨으로써 형성(形成)되는 것으로 여겨졌다.
