The Effect of Low Temperature on the Germination and Survival of Native Oaks

Studies in the distribution of the native trees and shrubs of the prairie region of Iowa and eastern Nebraska have yielded data pertaining to oak species which are difficult to interpret without further research directed at the determination of the response of each plant to single environmental conditions. Studies of the response of the acorns and seedlings of the four species to temperature, soil moisture and light are being made. In this paper are presented data on the response of the acorns and seedlings to low temperature
