酢浆草属植物观赏性评价体系的建立与应用

通过运用层析分析法筛选出株型、株高、花色等14个酢浆草属（Oxalis）植物观赏性状评价指标,对随机选择的40个球根酢浆草属植物进行观赏性评价。结果表明：应用层次分析法,可以有效地从观赏性方面对酢浆草属植物进行评价。14个指标中,株型、花色、冠幅、花量所占权重值均较大（>0.09）,是影响酢浆草属植物观赏价值最重要的指标。在评分标准中,心形叶、白花、肉质叶、大花径分值较高,均为5分。为酢浆草属植物观赏盆栽品种（种）的选择、DUS测试指南性状指标的筛选、育种亲本选择提供参考依据。40个参评植物中观赏价值较高的有钝叶酢‘锂辉石’（O. obtuse ‘Kunzite’）、芙蓉酢‘晨光’（O. purpurea ‘Alba’）和迷糊酢（O. ambigua）等6种,其得分均>3.499,这几种植物观赏性高、适应性强,是极具开发和应用价值的优良植物材料。

Establishment and Application of Ornamental Evaluation System for Oxalis

In this paper, 14 evaluation indexes of ornamental characters such as plant type, plant height and flower color were selected by chromatographic analysis, and 40 randomly selected plants were evaluated. The application of analytic hierarchy process could effectively evaluate the ornamental value of Oxalis. Among the 14 indexes, the weight values of plant type, flower color, crown width and flower quantity were all larger (>0.09), which were the most important indexes affecting the ornamental value of Oxalis. In the scoring standard, the scores of heart-shaped leaf, white flower, fleshy leaf and large flower diameter were all 5 points. The purpose of this study is to provide a reference basis for the selection of ornamental potted varieties / species of Oxalis, the selection of character indexes of DUS testing guidelines and the selection of breeding parents. Among the 40 plants, there were six kinds of plants with high ornamental value such as O. obtusa ‘Kunzite’, O. purpurea ‘Alba’ and O. ambigua, all of which scored more than 3.499. The Oxalis plants are highly ornamental and adaptable, and are excellent plant materials with great development and application value.
