目的研究陕产茜草种子的质量分级标准。方法对20个不同居群的陕产茜草种子的品质进行各项检测,并将各项数据进行逐级聚类分析作为分级依据的参考。结果以陕产茜草种子净度、千粒重、含水量、饱满度、发芽率和种子活力为指标,初步确定了陕产茜草种子的三级质量标准。其中,发芽率、种子活力和千粒重作为主要分级依据,净度、含水量、饱满度作为次要分级依据。结论本研究制定的陕产茜草种子三级质量标准符合实际情况,为陕产茜草种子的质量评价和人工栽培提供了参考和指导。
Objective To study the quality grading standard of Rubiaceae. Methods The quality of Rubia cordifolia seeds in 20 different populations was tested, and the data were classified by cluster analysis. Results The third grade quality standard of Rubiandus indicus seeds was initially determined with the index of the seed purity, 1000-grain weight, water content, plumpness, germination rate and seed vigor of Rubia cordata. Among them, the germination rate, seed vigor and grain weight as the main grading basis, clarity, water content, plumpness as a secondary grading basis. Conclusions The third-grade quality standard of Rubia cordifolia cultivars developed in this study accords with the actual situation and provides reference and guidance for the quality evaluation and artificial cultivation of Rubia cordifolia.
