Research demonstrates the impact of low temperatures on leaf metabolism in early maturing corn, indicating their cold tolerance.

This research explores how nighttime cooling affects the metabolic processes of early maturing corn leaves.
Exposed corn plants to nighttime temperatures of 5°–6°C for three nights and returned them to normal conditions.
Measured leaf samples within an hour post-exposure to assess hydrogen peroxide accumulation and enzyme activity.
Assessed photosynthesis and respiration at different temperatures (25°C and 6°C) to determine their dependence on temperature.
Hydrogen peroxide levels peaked after three nights of low temperature exposure, increasing enzyme activity for detoxification.
After seven nights, hydrogen peroxide decreased but remained higher than control values.
Photosynthesis and respiration were more affected by measurement temperature than by nighttime cooling, with significant declines at 6°C.

Golovko et al. (2025) studied this question.
