ホームユースのシクラメン鉢物の生育が消費者の感情に及ぼす影響(普及・教育・利用)  [in Japanese] Effects of Growth and Development of Potted Cyclamen as a Home-Use Flower on Consumers' Emotions(Human Issues & Methodology in Hoticulture)  [in Japanese]

冬季に人気の高い室内植物であるシクラメン鉢物を用い,育てる人による生育の違いやその生育状況が人に与える影響を調査した.栃木県在住の女性(46名,平均46.1才)を被験者とし,各自宅で栽培してもらいながら生育と心理的な調査を行った.3か月間の生育と品質は被験者による変動が大きかったため,植物の生育状態別により被験者を五つのGradeに分類した.植物の生育と被験者の自己評価(r=0.7,p<0.001),満足感(r=0.61,p<0.001)および楽しさ(r=0.38,p<0.012)との間には有意な相関が認められた.気分を評価するPOMSの測定では植物の介入によって緊張-不安,抑うつ-落込み(D),怒り-敵意(A-H)および混乱の得点の有意な低下が認められた.特にGrade 5(生育良好)の被験者においてDおよびA-Hの顕著な低下が認められた.Grade 5グループにおいてエゴグラムの適応した子供の自我が低下し,養育的,大人の自我および自由な子供の自我の得点が増加傾向にあった.鉢物を置いた部屋の印象を26項目のSD法で解析したところ,「快適さ」と「華やかさ」は高まり,「簡素さ・清潔さ」は低下する傾向が認められた.以上の結果から,鉢物が消費者のD,A-H,「快適さ」などの感情に好影響を与えるだけでなく,その生育状況と満足や楽しさなどに関係があることが示唆された.

Potted cyclamens, a popular indoor plant during the winter season, were used in this study. Differences in plant growth status depending on the individuals who cared for them and the responses of human emotion to the plant were examined. Forty-six women (mean age = 46.1) living in Tochigi prefecture were asked to care for potted cyclamens in their homes for three months. Growth and quality varied greatly with the subjects. The plants were classified into five groups depending on their status after three months. Self-evaluation (r = 0.7, p < 0.001), satisfaction (r = 0.61, p < 0.001) and pleasure (r = 0.38, p < 0.012) of the subjects correlated with the growth and quality of the plant in their care. On POMS, the scores for Tension-Anxiety (T-A), Depression-Dejection (D), Anger-Hostility (A-H), and Confusion (C) dropped significantly due to the intervention of the plant into the household, but these scores were slightly increased on the final test after three months. The categories of D and A-H were especially decreased in the group with the best plant quality. On the egograms in the group with the best quality plants, the scores for Nurturing Parent (NP), Adult (A) and Free Child (FC) were slightly increased, while that of Adapted Child (AC) was decreased. As for the semantic differential technique, factor analysis was performed based on twenty-six semantic differential (SD) scales on sensory evaluation. Among the three extracted factors, 'comfortable' and 'gorgeous' increased but 'simple and clean' decreased with the introduction of the potted cyclamen. The results indicated not only positive effects of potted plants on consumers' emotions, shown by scores for as D, A-H and 'comfortable', but also a certain level of relationship between plant growth and the satisfaction and pleasure of the owner.
