Anaerobically treated seedlings of Oryza sativa L. var arborio accumulated in their shoots more succinate than lactate and cell sap became alkaline. Conversely, in Triticum aestivum L. var MEK 86 lactate accumulation was far higher than that of succinate and cell sap was acidified. Anoxia clearly induced proton consumption in both species as an important means to prevent or counteract acidosis. Other species studied were: Echinochloa crus-galli L. Beauv., Zea mays L. var De Kalb XL75, Secale cereale L. var primizia and Hordeum vulgare L. var rondo. Changes in cell sap pH and succinate to lactate ratios distinguished resistant from nonresistant species.
