Abstract
Chlorophyll fluorescence analysis was conducted to evaluate why the fr ost-hardened winter rye is more resistant to photoinhibition of photos ynthesis at 5-degrees-C than the non-hardened winter rye. Under a simi lar irradiance, the leaves of frost-hardened rye were able to keep a l arger fraction of photosystem 2 reaction centres open than those of no n-hardened rye. This ability of the frost-hardened rye fully accounts for its higher resistance to photoinhibition.
