Wheat, soybean, and oat germination studies with particular reference to temperature relationships
1928
Wilson, H.K.
This paper reports studies of the germination of different varieties of three major farm crops--wheat, soybeans, and oats. The wheat varieties tested were Turkey, Red Rock, and Marquis, representatives of the three most important market classes, viz., hard red winter, soft red winter, and hard red spring, respectively. Soybean varieties tested were Manchu, Virginia, and Wilson. Only one variety of oats, the Silvermine, was included. Samples of each variety were obtained from various agricultural experiment stations and germinated on plaster of paris blocks at five constant temperatures of 10, 15, 20, 25, and 30 degrees C. Not less than 100 seeds were used in making a germination test, and every germination test was repeated. Each of the two tests was performed at different periods of time and not concomitantly. Duplicate tests made at the same time and under identically the same conditions are of value only in so far as the total number of seeds is increased. The same results would be obtained by doubling the number of seeds and performing a single germination test.
