Abstract
It was recently reported that salicylic acid (SA) treatment may provide protection against low temperature stress in young maize plants (JANDA et al. 1999). In the present study it is shown that certain related compounds (benzoic acid, acetyl SA) may also reduce the symptoms of chilling injury in young maize plants At normal growth temperature, however, these compounds may cause severe damage to the plants. There is a decrease in net photosynthesis stomatal conductivity and transpiration after 1 day of benzoic acid or aspirin treatment at 22/20°C. These compounds may cause a decrease in the growth rate in young developing maize seedlings It is suggested that an alteration in the activity of antioxidant enzymes may play a role in the increased chilling tolerance induced by these compounds.
