摘　　要：分析不同颜色桔梗种子发芽情况的差异,采用不同的种衣剂包衣桔梗种子,以此提高桔梗种子的发芽率和利用率。通过观察并测定10个产区桔梗种子的外部形态,根据颜色分类考察其含水量、千粒重、发芽势、发芽率等指标,并用不同的种衣剂包衣种子,以此确定优质桔梗种子发芽的标准和筛选一种适合桔梗种子包衣的种衣剂。结果表明,桔梗种子主要分为黑色种子、黄色种子、绿色种子三类,发芽率分别为82.3%~88.3%,50.3%~57.0%,38.7%~44.0%。桔梗种子用B种衣剂T3浓度包衣后,种子在纸床中的发芽率比对照提高约7%,发霉率降低约13%,种子在沙床中的出苗率比对照提高约10%。因此,黑色组桔梗种子最好,而且用B种衣剂T3浓度处理效果最好。To analyze the difference of germination ofPlatycodon grandiflorumseeds with different colors,and to improve the germination rate and utilization rate ofP.grandiflorumseeds with different seed coating agents.Through observation of the appearance ofP.grandiflorumseeds from 10 areas,the color classification was used to observe the water content,1000-grain weight,germination potential,germination rate and other indicators,the seeds were coated with different seed coating agents to determine the germination standared ofP.grandiflorumseeds,and to screen a seed coating agent suitable forP.grandiflorumseeds.The results showed that,P.grandiflorum seeds were mainly divided into black seeds,yellow seeds and green seeds.The germination rates were 82.3%~88.3%,50.3%~57.0%and 38.7%~44.0%,respectively.After theP.grandiflorumseeds were coated with T3 concentration of B seed coating agent,the germination rate of the seeds in the paper bed was about 7%higher than the control,and the mildew rate was reduced by about 13%.The seedling rate of the seeds in the sand bed was about 10%higher than that of the control.Therefore,the blackP.grandiflorumseeds are the best,and the effect of treatment with T3 concentration of B seed coating agent is the highest.
