RESUMO
Bark tissues of Cornus stolonifera stems, treated with cysteine at 24 hours after treatment, survived exposure to −11 C (the tissue temperature) with little or no injury. An initiation of increase in the cold tolerance was usually observed when plants were treated with cysteine at 12 hours after treatment. Neither plants at 36 or 48 hours after treatment nor plants 12 hours before treatment had shown increases in the cold tolerance. They were killed below −5 C, which was the survival temperature of untreated control plants. Two weeks or more of short day induction before cysteine application were required for a significant effect of short term 5 C increase in the cold tolerance.
