An activity of ascorbate peroxidase, which is an antioxidative enzyme in pansy petals increased markedly under the condition of high temperature (25 ~C ) and the enzyme activity attained 3-fold higher level at 6 days after the treatment of high temperature. This was followed by a steep decrease in the enzyme activity at 9 days after the treatment. However, the flowers of pansy at 6 days after the treatment of high temperature were apparently small and few with a little withering, compared with those at 3 days after the treatment. From these results, the ascorbate peroxidase may be used as a marker enzyme of evaluation of environment in pansy flowers stressed by higher temperature in the natural environment where the plant grows.
