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
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
