Chestnut wood: Note the splitting at the top of the log. Chestnut is of the same family as oak, and likewise its wood contains many tannins. [38] This renders the wood very durable, [38] gives it excellent natural outdoor resistance, [38] [108] and saves the need for other protection treatment. It also corrodes iron slowly, although copper ...
The American chestnut is a prolific bearer of nuts, with inflorescence and nut production in the wild beginning when a tree is 8 to 10 years old. [35] American chestnut burrs often open while still attached to the tree, around the time of the first frost in autumn, with the nuts then falling to the ground. [36]
The sweet chestnut is naturally self incompatible, meaning that the plant cannot pollinate itself, making cross-pollination necessary. [5] Some cultivars only produce one large seed per cupule, while others produce up to three seeds. [5] The nut itself is composed of two skins: an external, shiny brown part, and an internal skin adhering to the ...
The tree is located in the wood of Carpineto, on the eastern slope of the Etna volcano, near zone D of the Etna park. Authors of botany agree the chestnut tree is thousands of years old but do not agree on its exact age. [clarification needed] It is likely between two and four thousand years old. The thesis of the Turin botanist Bruno Peyronel ...
Many of these trees may be even older than their listed ages, but the oldest wood in the tree has rotted away. For some old trees, so much of the center is missing that their age cannot be directly determined. Instead, estimates are made based on the tree's size and presumed growth rate. The second table includes trees with these estimated ages.
Trees being coppiced do not die of old age as coppicing maintains the tree at a juvenile stage, allowing them to reach immense ages. [1] The age of a stool may be estimated from its diameter; some are so large—as much as 5.5 metres (18 ft) across—that they are thought to have been continually coppiced for centuries. [6]

For three centuries many barns and homes near the Appalachian Mountains were made from American chestnut. [20] Its straight-grained wood was ideal for building furniture and caskets. The bark and wood were rich in tannic acid, which provided tannins for use in the tanning of leather. [21] Chestnuts were an important cash crop and food source.
