| 摘要: |
| 为了探索出五指毛桃种苗科学合理的质量分级标准，采用相关分析、逐步聚类分析方法对五指毛桃种苗进行分级。结果表明，可以选用地径与冠幅作为五指毛桃种苗的分级指标。五指毛桃种苗的分级标准为Ⅰ级种苗：地径≥2.39 mm，冠幅≥13.55 cm；Ⅱ级种苗：地径≥1.93 mm，冠幅≥10.58 cm；Ⅲ级种苗：地径＜1.93 mm，冠幅＜10.58 cm。本研究制定了五指毛桃质量分级标准，可为将来五指毛桃种苗的标准化生产提供科学依据。 |

| Abstract: |
| In order to explore a scientific and reasonable quality grading standard for the seedlings of Ficus hirta Vahl correlation analysis and stepwise cluster analysis were used to grade the seeds and seedlings of F.hirta Vahl.The results showed that ground diameter and crown width could be used as grading indexes of Ficus hirta seedlings.The grading standard of F.hirta Vahl seedlings was as follows.Grade Ⅰ seedlings:ground diameter≥2.39 mm,crown width≥13.55 cm.Grade Ⅱ seedlings: ground diameter≥1.93 mm,crown width≥10.58 cm.Grade Ⅲ seedlings,ground diameter<1.93 mm,crown width<10.58 cm. In this study,the quality grading standard of F.hirta Vahl was established,which would provide scientific basis for standardized production of F.hirta Vahl seedlings in the future. |
