蒙古黄芪种子质量评价研究

Evaluation on Seed Quality of Astragalus membranaceus var. mongholicus

为确定最优蒙古黄芪质量参数,以实现蒙古黄芪种子的精量播种和包衣丸粒化,对16个不同产地蒙古黄芪种子的外部形态、净度、千粒重和发芽率进行检验,并对山西3个不同产地不同粒径蒙古黄芪种子净度、千粒重、发芽率、含水量等指标进行研究,利用SPSS进行方差分析,探寻蒙古黄芪种子粒径最优质量参数。结果表明,山西三种蒙古黄芪种子分为4级粒径,2.3~2.5 mm粒径蒙古黄芪种子最优,千粒重在6.887 0~6.945 0 g之间,含水量在8.43%~9.73%,发芽盒发芽率在94.4%~96.8%之间,沙盒发芽率在82.4%~91.6%之间,大田出苗率在46.0%~61.5%之间。

In order to determine the optimal quality parameters of Astragalus membranaceus var. mongholicus and realize the precise sowing and coating pelletization of Astragalus membranaceus var. mongholicus seeds, the external morphology, clarity, 1000-grain weight and germination rate of Astragalus membranaceus var. mongholicus seeds from 16 different origins were tested. The indexes such as purity, thousand-grain weight, germination rate and water content of Astragalus membranaceus var. mongholicus seeds with different particle sizes in 3 different producing areas of Shanxi were studied, and SPSS was used to analyze the variance to find the optimal quality parameters of Astragalus membranaceus var. mongholicus seed particle size. The results showed that the three kinds of Astragalus membranaceus var. mongholicus seeds in Shanxi were divided into 4 grades of particle size. The seeds of Astragalus membranaceus var. mongholicus with a particle size of 2.3-2.5 mm were the best, the thousand-grain weight was between 6.8 870 and 6.9 450 g, the water content was between 8.43% and 9.73%, and the germination rate of the germination box was between 94.4% and 96.8%, the sandbox germination rate was between 82.4% and 91.6%, and the field seedling rate was between 46.0% and 61.5%.
