摘要
为提出当归种子的质量标准,规范种子供需市场,参考农作物种子的扦样、种子净度、千粒重、水分含量、种子活力、发芽率和健康度等检验规程,对岷归1号、岷归2号及其火药种子和野生当归种子进行品质检验。结果表明,不同当归种子净度为93.43%～91.94%,千粒重1.5087～1.6888g,种子含水量12.19%～12.89%,种子活力48.50%～60.00%,发芽势33.00%～64.00%,发芽率65.50%～86.00%,病种率3.7333%～5.3300%,死虫和卵含量0.0362%～0.0806%;岷归2号种子、岷归2号火药种子和野生当归种子在千粒重、种子活力和发芽能力方面均优于岷归1号种子和岷归1号火药种子,其中野生种子中死虫和卵含量显著高于其他种子,但病种率显著低于其他种子。通过对不同当归品种及不同种子对比研究,提出了供生产应用的岷归1号和岷归2号当归种子分级标准建议。
The quality standards of the Angelica seeds are put forward so as to standardize the market of seeds supply and demand. Five kinds of Angelica seeds including Mingui No. 1, Mingui No. 2 and its＂ Huoyao seeds, and wild seeds were tested by crop seed inspection code to provide a basis for the classification of Angelica seeds. The main results are as follows. The punty of different Angelica seeds is in the range of 93.43%-91.94%, the weight of a thousand seeds is in the range of 1.5087-1.6888g, the moisture content is in the range of 12.19%-12.89%, the seed vitality is in the range of 48.50%-60.00%, the germinating energy is in the range of 33.00%-64.00%, the germination percentage is in the range of 65.＇50%-86.00%, the percentage of diseased seeds is in the range of 3.7333%-5.3300%, the percentage of dead pests and eggs is in the range of 0.0362%-0.0806%. Minggui No. 2, Huoyao seeds of Minggui No. 2 and wide Angelica seeds arc superior to Minggui No. 1 and Huoyao seeds of Minggui No. 1 with respect to the weight of a thousand seeds, the seed vitality and the germination ability. In wild Angelica seeds, the content of dead pests and eggs is higher than that for the other seeds, but the percentage of diseased seeds is lower than that for the other seeds significantly. Based on the comparison of different species and different seeds, suggestions are made for classification standard about Angelica seeds of Mingui No. 1 and Mingui No. 2 used in production.
