Abstract
Growth and nutrient uptake of red oak seedlings were studied under conditions simulating a forest understory. The tallest seedlings grew in 30% of full light; seedlings in full light had the greatest dry weight accumulation. Seedlings in full light had an average height of 9.7 inches, and those at 30% and 10% light averaged 12.9 and 8.8 inches respectively. Only seedlings in 30% or more light responded in height growth to an NPK fertilizer. Seedlings in 10% light accumulated nutrients, but showed no growth response to fertilization. Thus, fertilization did not lower the minimum light requirements.Keywords
