Acorns yaiku 1–6 centimetres (0.39–2.36 inches) dawane lan 0.8–4 cm (0.31–1.57 in) ing sisih lemu. Acorns njupuk antara 6 lan 24 wulan (gumantung saka spesies) kanggo diwasa; deleng dhaptar spesies <i id="mwKg">Quercus</i> kanggo rincian klasifikasi oak, ing endi morfologi lan fenologi akorn minangka faktor penting.
Peran ekologis[besut | besut sumber]
Acorns duwe peran penting ing ekologi alas nalika wit ek minangka spesies sing dominan utawa akeh. [1] Volume panen akorn bisa beda-beda beda-beda, nggawe akeh utawa stres gedhe kanggo akeh kewan sing gumantung karo acorn lan predator kewan kasebut. [2] Acorn, uga kacang-kacangan liyane, diarani mast .
Margasatwa sing ngonsumsi acorn minangka bagean penting saka panganan kalebu manuk, kayata jays, pigeons, sawetara bebek, lan sawetara spesies pelatuk . Mamalia cilik sing mangan acorn kalebu tikus, bajing lan sawetara tikus liyane. Acorn duweni pengaruh gedhe marang rodent cilik ing papane, amarga panen biji gedhe mbantu populasi tikus tuwuh
