Physiological Factors Affecting Composition of Soybeans: II. Response of Oil and Other Constituents of Soybeans to Temperature Under Controlled Conditions1

Synopsis Oil content averaged 23.2%, 20.8%, and 19.5% when day temperatures of 85°, 77°, and 70° F., respectively, were used during the pod‐filling stage. A day temperature of 85° for one week during this period increased oil content from 19.6% to 22%. Temperature treatments affected mainly the triglyceride portion of the oil. Acetone‐insolubles in the oil, protein and nonprotein nitrogen, and yield were not affected significantly.
