橡子产量变化极大且不可预测。开花是丰富的，但许多气候因素影响橡子的发展，从开始的花，橡子成熟。橡子被鸟类、动物、昆虫和微生物消耗。幼苗的建立与有利的立地因素的关系比与作物的大小的关系更密切。大多数橡树起源于几十年来积累在以前的立场下的提前繁殖。
Acorn production is extremely variable and unpredictable. Flowering is copious, but many climatic factors influence acorn development from initiation of flowers to acorn maturity. Acorns are consumed by birds, animals, insects, and microorganisms. The establishment of seedlings is more closely related to favorable site factors than to size of crops. A majority of oaks originate from advance reproduction that accumulates under the previous stands during several decades.
