Abstract

When maize plants (Zea mays L. line ps‐lye) were subjected to chilling (at 8 ± 2°C, 80% relative humidity for 24 h under illumination by 80 W m2 between 400–700 nm), the leaves were wilted and photosynthetic membranes were permanently damaged. This was shown by the swelling of grana thylakoids and a deerease in the charging capacity of the electron transport chain. Water loss and photosynthetic dysfunction were connected in the process of a chilling‐induced increase of stomatal aperture. Chilling injury could be eased to a considerable extent by a mild treatment with DCMU preventing stomatal opening, wilting, and the irreversible loss of CO2 fixation capacity.
