T. Janda et al., ROLE OF IRRADIANCE IN THE CHILLING INJURY OF YOUNG MAIZE PLANTS STUDIED BY CHLOROPHYLL FLUORESCENCE INDUCTION MEASUREMENTS, Photosynthetica, 30(2), 1994, pp. 293-299
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.
