为制定商洛桔梗(Platycodon grandiflorum)种子的质量标准,规范种子供需市场,参考种子净度、千粒重、含水量、种子活力、发芽率等检验规程,对商州A号、商州B号、丹凤、商南和山阳桔梗种子进行品质检验。结果表明,不同桔梗种子净度为52.38%~92.19%,千粒重0.9735~1.0930 g,135℃高温法含水量7.53%~7.85%,发芽势55.5%~87.0%,发芽率61.0%~88.0%,发霉率1.33%~5.67%,生活力72.0%~90.5%,活力指数0.0112~0.0243,种子的颜色有黑色和黄褐色两种。商州A号种子在净度、千粒重、发芽能力方面均优于其他4种种子。采用发芽试验与TTC法测定的桔梗种子生活力基本一致。通过对商洛不同县(区)桔梗种子的对比研究,选用种子净度、千粒重、生活力和发芽率为主要分级指标,把商洛桔梗种子初步分成3类,提出了供生产应用的商洛桔梗种子分级标准建议。
為製定商洛桔梗(Platycodon grandiflorum)種子的質量標準,規範種子供需市場,參攷種子淨度、韆粒重、含水量、種子活力、髮芽率等檢驗規程,對商州A號、商州B號、丹鳳、商南和山暘桔梗種子進行品質檢驗。結果錶明,不同桔梗種子淨度為52.38%~92.19%,韆粒重0.9735~1.0930 g,135℃高溫法含水量7.53%~7.85%,髮芽勢55.5%~87.0%,髮芽率61.0%~88.0%,髮黴率1.33%~5.67%,生活力72.0%~90.5%,活力指數0.0112~0.0243,種子的顏色有黑色和黃褐色兩種。商州A號種子在淨度、韆粒重、髮芽能力方麵均優于其他4種種子。採用髮芽試驗與TTC法測定的桔梗種子生活力基本一緻。通過對商洛不同縣(區)桔梗種子的對比研究,選用種子淨度、韆粒重、生活力和髮芽率為主要分級指標,把商洛桔梗種子初步分成3類,提齣瞭供生產應用的商洛桔梗種子分級標準建議。

The quality standards of Shangluo Platycodon grandiflorum seeds were put forward to standardize the market of seeds. Five kinds of P. grandiflorum seeds including Shangzhou NO.A, Shangzhou NO.B, and Danfeng,Luonan,Shanyang seeds were tested to provide a basis for the classification of P. grandiflorum seeds. Results showed that, the purity of different P. grandiflorum seeds was 52.38%~92.19%. The weight of a thousand seeds was 0.973 5~1.093 0 g. The moisture content was 7.53%~7.85%. The germination energy was 55.5%~87.0%. The germination rate was 61.0%~87.0%. The moldy rate was 2.0%~5.67%. The vitality was 72.0%~90.5%. The vigor index was 0.011 2~0.024 3. Seeds color were black and tawny. Shangzhou NO.A seeds was superior to the other four seeds with respect of seeds purity, thousand-seeds weight,the seed vitality and germination ability. Shangzhou NO.B seeds were lower than the other four seeds significantly in three indexes. The seed viability of the germination test and TTC method was almost consistent. Based on the comparison of five species, selection of purity, weight of a thousand seeds and germination rate of the main classification index, Shangluo Platycodon grandiflorum was divided into three kinds. The classification standards about P. grandiflorum seeds of Shangluo in production were proposed.
