In Zea mays L., Bryophylum laxiflorum Bak., Gossypium hirsutum L., Helianthus annuus L., Oryza sativa L. and Vigna radiata L., a pre‐illumination in nitrogen causes transient stomatal opening upon returning the plant to darkness and normal air. In Zea mays L. hybrid INRA 508, K + and Cl − fluctuations in the stomatal complex during this stomatal opening in darkness were similar to those observed during a light‐induced opening in normal air. These results are consistent with a two‐phase mechanism for stomatal opening: a light phase that may occur in the absence of oxygen and carbon dioxide, and a dark phase during which oxygen is necessary for ion accumulation and other mechanisms of osmotic adjustment.
