Studies on the characteristics of electroencephalogram inspecting a plant : The potted plants of Pelargonium hortorum BAILEY u22Sprinter Redu22 and Begonia evansiana ANDR.

摘要

We analyzed the quantity of alpha rhythm of sabjects immediately after inspecting the potted plants of Pelargonium and Begonia with and without flowers, and a pot without plant and a 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 subjects 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 L/R ratios of alpha rhythm between the flowered and the unflowered Pelargonium, and the subjects with higher ratios in the unflowered plant are mostly male and the subjects with higher ratios in the flowered are mostly female. Therefore, the subjects, who increase the quantity of alpha rhythm in their right hemisphere or decrease it in the left after inspecting the flowered plants, are mostly male. On the other hand, the subjects, wto decrease the quantity of alpha rhythm in their right hemispere of increase it in the left after inspecting the flowered plants, are mostly female.
