在种子发育期间，将油菜、红花、向日葵、亚麻和蓖麻子的植物在10、16、21和26.5 ℃的温度下生长。向日葵、红花和蓖麻子的含油量不受温度的影响。油菜和亚麻的含油量在最低温度时最高，随着温度的升高，含油量不断下降。从红花和蓖麻子油的脂肪酸组成不受温度的变化。在其他三个物种的量更高度不饱和脂肪酸的温度升高而下降。这种减少伴随着油酸的增加。所有物种的饱和脂肪酸水平不受温度变化的影响。
Plants of rape, safflower, sunflower, flax, and castor bean were grown at temperatures of 10, 16, 21, and 26.5 C for the period of seed development. Oil content of sunflower, safflower, and castor bean was not affected by temperature. Highest oil content in rape and flax was found at the lowest temperature and a continual decrease was observed with increases in temperature. Fatty acid composition of the oil from safflower and castor bean was not affected by a change in temperature. In the other three species the amount of the more highly unsaturated fatty acids decreased as the temperature was increased. This decrease was accompanied by an increase in oleic acid. The levels of saturated fatty acids in all of the species were not affected by changes in temperature.
