Maturation of Acorns of Cherrybark, Water, and Willow Oaks

Abstract Acorns of cherrybark, water, and willow oaks grew slowly but steadily in July and August and reached maximum size in September, when fats and carbohydrates, the major storage foods, accumulated rapidly. At physiological maturity in late October or early November, crude fat levels were 15 to 20 percent of seed dry weight and carbohydrates totaled 25 percent. Forest Sci. 20:238-242.
