Abstract
We analyzed the quantity of alpha rhythm of subjects immediately after inspecting the potted plants of Pelargonium and Begonia with and without flowers, and a pot without plant and cylinder similar to the pot as a comparison. The quantity of alpha rhythm is the most in case of the flowered plants of both species, and the quantity in case of unflowered plants is less than flowered plants, but keep constant values as the flowered plants. Comparing the quantity of alpha rhythm of each subject between flowered and unflowered plants, the results are stable in case of Pelargonium but not in Begonia. The subjects with more alpha in the flowered Pelargonium than unflowered are mostly male, and contrarily the subjects with more alpha in the unflowered plant are mostly female. Then we compared the alpha frequency of each subject between flowered and unflowered plants. The result, most of subjects are not stable in alpha frequency in case of Pelargonium. On the other hand, the subjects with higher frequency in the flowered Begonia are more than in the unflowered. Therefore the subjects, who show a tendency to be stable in Begonia, are more than in Pelargonium. On the first stimulus, most of subjects tend to have higher frequency in the flowered plants than in the unflowered. We think the flowered plants stimulate most of subjects to have high frequency.
