Also known as bole, tree trunk, log
main wooden axis of a tree
A trunk is the main wooden part of a tree that grows upward from the ground and supports the branches and leaves above it. It matters because it provides the structural strength that allows trees to grow tall and reach sunlight, while also transporting water and nutrients throughout the tree.

樹幹（じゅかん、Trunk）は、木の主要構造部分で、枝を支え、根に直接つながって支えられている。樹幹を覆う部分は樹皮と呼ばれ、樹皮は木の種類によって違い、種の判別にとって重要である。樹幹は、「真の」木の他にも、ヤシやその他の単子葉植物でも見られ、内部の生理はそれぞれの場合によって異なる。全ての植物で、樹幹は二次成長（単子葉植物の場合は擬二次成長）によって年々太くなる。樹幹は、日焼け等のダメージに弱い。
