Abstract
During cold treatment of Zea mays L. plants there was a decrease in th e level of F-v/F-m and in the quantum yield of photosynthetic electron transport. The degree of damage depended on the ambient temperature a nd on the irradiance (I). The lower the temperature and the higher the I; the more pronounced damage occurred. This suggests that photoinhib ition has an important role in the cold damage to young maize. Althoug h there was no damage in complete darkness even at low temperature, th e repair precesses needed a normal temperature.
