摘要
【目的】以17个种和栽培品种的葡萄风信子为材料,研究其花序色彩的公众喜好度。【方法】基于美景度评价法(SBE),采用网络问卷调查的形式,收集公众对葡萄风信子花序色彩的喜好度,并计算其SBE标准化值,提取影响公众喜好度的主要评价因子,建立评价模型。【结果】葡萄风信子花序色彩SBE值13个分值在0分以上,评价员对其表现较为普遍的积极态度(喜欢或很喜欢),不同性别、专业的评价员审美也具有相对一致性。经过向后(Backward)筛选因子建立模型:SBE=1.632+0.597X1-0.017X10+0.047X11-0.064X13。通过模型得到了影响葡萄风信子花序色彩公众喜好度的4个因子,分别为色彩鲜艳感(X_(1))、色相对比度(X_(10))、明度对比度(X_(11))和花序冠幅(X_(13)),这4个评价因子与公众喜好度呈极显著线性关系。各因子对葡萄风信子花序色彩公众喜好度的贡献率由大到小排序为:明度对比度>色彩鲜艳感>花序冠幅>色相对比度。【结论】葡萄风信子花序色彩的公众积极态度频率与SBE值均可体现公众喜好度变化趋势。SBE法适用于葡萄风信子花序的色彩评价,可以拓宽其应用领域。
【Objective】To study the public’s preference for inflorescence color,the sample was based on 17 species and cultivars of grape hyacinth.【Method】Based on the SBE method,a web-based questionnaire was used to collect the public’s preference for grape hyacinth inflorescence color and calculate its SBE standardized value,extract the main evaluation factors affecting public’s preference,and establish an evaluation model.【Result】Thirteen of the SBE scores for grape hyacinth inflorescence color were above 0 Evaluators showed a more generally positive attitude toward it(liked it or liked it a lot),and there was also a relative consistency in aesthetics among evaluators of different genders and professions.After backward(Backward)screening of the factors,the model was built after six screenings:SBE=1.632+0.597X1-0.017X10+0.047X11-0.064X13,retaining four factors,namely the color vibrancy of the grape hyacinth inflorescence(X_(1)),hue contrast(X10),brightness contrast(X_(11)),and crown width of the inflorescence(X_(13)).The four evaluation factors showed a highly significant linear relationship with their public preference,and the contribution of each factor to the public preference of grape hyacinth inflorescence color was in descending order:brightness contrast>color vividness>inflorescence crown width>color contrast.【Conclusion】Both the frequency of positive public attitudes and the SBE values for grape hyacinth inflorescence colors indicate trends in public preference.The SBE method can be applied to evaluate the color of grape hyacinth inflorescences and can be used to broaden the scope of its application.
