摘  要:
[目的]建立赣南八角1年生容器苗分级标准。[方法]以苗高和地径为分级质量指标,采用逐步聚类分析方法,对八角1年生容器苗苗木分级标准进行研究。[结果]八角1年生容器苗木的3级分级标准为Ⅰ级苗:苗高≥19 cm,地径≥0.25 cm;Ⅱ级苗:15 cm≤苗高<19 cm,0.20 cm≤地径<0.25 cm;Ⅲ级苗:苗高<15 cm,地径<0.20 cm。[结论]该研究可为赣南八角苗木生产中的质量判别和分级提供科学依据。

摘  要:
[Objective] To establish grading standard of 1-year-old container seedlings of Illicium verum in southern Jiangxi Province.[Method]Adopting the method of cluster analysis,classification of 1-year-old container seedlings of I. verum was discussed with seedling height and basal diameter as the index of seedling quality.[Result]Three grading standards were proposed as following: gradeⅠ: seedling height≥19 cm,basal diameter ≥0. 25 cm; grade Ⅱ: 19 cm > seedling height ≥15 cm,0. 25 cm > basal diameter≥0. 20 cm; grade Ⅲ: seedling height < 15 cm,basal diameter < 0. 20 cm.[Conclusion] The study can provide a scientific basis for quality judgment and classification in production of I. verum in southern Jiangxi Province.
