Abstract

The aim of the research was the determination of changes in the antioxidant system of eggplant seedlings during chilling acclimation. The sequential measurements of stress-depended parameters were performed after two, four, and fix days of chilling at 6°C, while 18°C was the control temperature. “Epic” F1 showed the highest chilling sensitivity; indeed, H202 malondialdehyde (MDA) and antioxidant activity increased, indicating that effective mechanism were not activated sufficiently to alleviate stress symptoms “WA 6020” F1 was less chilling-sensitive. Its defense system were sufficient to scavenge the excess of reactive oxygen species (ROS), but after a reduction of the antioxidant activity on the 4th day of chilling. The genotype- dependent reaction of eggplant to chilling resulted form different ROS scavenging mechanisms involved in allevation of stress symptoms on physiological level.
