Table 3.

Species differences showing effects of supra-optimal growth temperatures on various foliar organic acids. Plants were grown for a minimum of three weeks with 28/20 or 36/28 °C growth temperatures. Sampled leaves were analyzed by a GC-MS procedure and values in bold print within species differed at p ≤ 0.05.
