| 摘 要： | 人参种子的长、宽、厚及其重量总体上呈正态分布，宽度总体平均值约为4．5mm，宽度〉4．5mm和〈4．5mm的分别占总体的48．56％和51．44％。不同产地人参种子大小分布范围没有显著差异，所有的品种宽度〉5．5mm或者〈3．5mm的种子均不足10％，但是不同品种的人参其种子在不同等级中所占比率不同。人参种子的宽／长比值范围为0．70～1．00，不同品种的人参种子宽／长比值分布范围完全一致，平均值基本相等。人参种子的厚／长比值范围为0．25—0．80，厚／宽度比值范围为0．3～0．9。不同品种人参种子厚／长比值和厚／宽分布范围有较大的差异，平均值差别较大。人参种子单粒重为10～50mg，其重量与种子宽度呈正相关关系，平均宽度和平均重量呈良好的线性相关性，相关系数（R^2）达0．9989。人参种子吸水后长、宽、厚度增长比例基本一致，干种子尺寸与吸水后种子的尺寸呈线性相关性（R^2=0．993）。充分吸收水分后长、宽、厚膨胀系数均为1．05左右。人参种子可采用圆孔种子筛进行有效地分级，分级结果符合国际种子检验规程的要求。

| Abstract: | The length, width and thickness of the seeds of Panax g/nseng C.A. Meyer were found to show normal bell- shape distribution. The average width of the seeds collected from different locations is approximately 4.5mm. There are approximately 51% seeds whose width is larger than 4.5mm in all these seeds. The width of seeds which is less than 4.5mm is 48.56 % in all these seeds. Either the seeds whose width is less than 3.5mm, or those whose width is larger than 5.5mm are less than 10% totally. However, the percentages of seeds in different scale were quite different among cultivars. The width to length ratio（W/L） of the seeds ranges from 0.70 to 1.00. The dispersions of W/L were found to be similar in different cultivars. The thickness to width ratio（H/W） ranges from 0.30 to 0.90, and the thickness to length ratio（H/L） is 0.25- 0.80. Both H/W and H/L are very different among cultivars. A single seed weighted from 10 to 50 rag. Positive linear correlation bet ween mean width and mean weight was observed（ R2 = 0.998 9） . It shows good positive linear correlation with the seed width. A very good lin- ear correlation has been found between the average seed weight and average width of the seeds（ R2 = 0. 993）. The coefficients of swelling of the length, width and thickness of ginseng seeds are all approximately 1.05. Seeds of P. g/nseng can be graded using screening fraction, and the graded results meet the criterion of international rules for seeding testing. |
