Abstract:

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.

Key words: Oxalis, analytic hierarchy process (AHP), ornamental value, ornamental evaluation, potted ornamental, autumn planting bulb
