Temperature has also been shown to affect total oil
and protein content of soybeans. Howell and Cartter (5,6)
reported a positive correlation between maximal temperature
and oil percentage. Additionally, both a negative
(7-9) and a positive (4) correlation between protein and oil
have been reported. Howell and Cartter (6) found that
protein was stable with relation to temperature, but nonprotein
nitrogen increased as the temperature rose.
