Lespedeza species, including both the annual and perennial, have come into unusual prominence during the past few years. With increasing interest in the crop, information as to the cold resistance of the different species has been demanded. Reports were received in March, 1932, of late freezes after most of the lespedeza seedlings had appeared in the field which were very destructive to the stands, in some places complete. Here and there, however, claims were made that one lespedeza or another endured a temperature as low as 16° F. In order to obtain more precise data on the minimum lethal temperature of various lespedezas and the influence of age on cold resistance, controlled freezing tests were undertaken through the use of the facilities of the Plant Pathology Department, Nebraska Agricultural Experiment Station.
