在肯塔基州东部进行的一项研究旨在了解白色橡树的雌花中有多少比例发育成成熟的橡子，该研究表明，大多数潜在的橡子作物都过早成熟。在1962年和1963年期间，从9棵白色橡树上收集的雌花和橡子只有1.3%和3.5%成熟。几乎90%的授粉发生在4月30日至7月15日，这是授粉、胚珠发育和受精的时期。
A study in eastern Kentucky, designed to learn what percent of the female flowers of white oak develop into mature acorns, indicates that most of the potential acorn crop is prematurely abscised. During 1962 and 1963, only 1.3 and 3.5 percent of the female flowers and acorns collected from nine white oak trees were mature. Almost 90 percent of all abscissions occurred from April 30 to July 15, the period of pollination, ovule development, and fertilization.
