Study on Seedling Quality Grading Standards of the Key Protec-ted Wild Plant Ardisia gigantifolia in Guangxi
摘要
Abstract
To explore the quality grading standard of Ardisia gigantifolia seedlings can lay a foundation for propagating high-quality A.gigantifolia seedlings and standardized production.In this study,300 seed seed-lings and 110 cutting seedlings of 2-year-old A.gigantifolia were used as materials.The plant height,crown width,ground diameter,leaf number,root length,root diameter,fresh weight above ground and fresh weight under ground of A.gigantifolia were measured.Principal component analysis and K-means cluster analysis were used to classify the quality grading standards of the seedlings.The results showed that:(1)The seed seedling standards of A.gigantifolia were follows.The plant height,ground diameter,crown width and leaf number of grade Ⅰ seedlings was＞52.00 cm,＞9.45 cm,＞34.83 mm,＞5.00,respectively.The plant height,ground diameter,crown width and leaf number of grade Ⅱ seedlings was＞37.00-52.00 cm,＞7.45-9.45 mm,＞28.31-34.83 mm,＞4.00-5.00,respectively.The plant height,ground diameter,crown width and leaf number of grade Ⅲseedlings was 20.00-37.00 cm,5.73-7.45 cm,22.37-28.31 mm,3.00-4.00,respectively.(2)The cutting seedling standards of A.gigantifolia were as follows:the plant height,ground diameter,crown width and leaf number of grade Ⅰ seedlings was＞57.00 cm,＞9.92 cm,＞38.48 mm,＞10.00,respectively.The plant height,ground diameter,crown width and leaf number of grade Ⅱ seedlings was＞41.00-57.00 cm,＞8.18-9.92 cm,＞31.68-38.48 mm,＞8.00-10.00,respec-tively.The plant height,ground diameter,crown width and leaf number of grade Ⅲ seedlings was 24.00-41.00 cm,5.76-8.18 cm,19.53-31.68 mm,5.00-8.00,respectively.The results of this study can provide technical support for the production quality control and resource protection of A.gigantifolia seedlings,and provide reference for the grading study of other key protected wild plants.关键词
