Growth temperature treatment effects on organic acids in soybean leaflets. Values are means for data collected one, two and three days after reciprocal temperature shifts between ambient (28/20 °C) and above ambient (36/28 °C) growth temperatures. Probabilities were determined by ANOVA and are for * (p ≤ 0.05), ** (p ≤ 0.01) and ns, not significant.
