Abstract: Chilling stress (10℃) at booting and filling stages, especially at booting stagedicreased photosynthetic rate and leaf area per plant, lowered SOD activity and in-creased MDA content and relative conductivity of leaf and ear (or kernel) in maize,thus causing chilling injury. Low temperature at boot

Key words: Chilling stress, Maize, kernel yield, Photosynthesis, SOD activity
