摘要:

研究当归果翅对其种子吸水及发芽进程的影响,旨在为当归规范化栽培提供理论和技术依据。以当归的双悬果果实和去翅种子作为试验材料,对其千粒重、含水量、体积、容重和吸水率进行测定,并在自然室温条件下进行种子发芽试验。结果表明:①当归双悬果去除果翅后,其千粒重减少了46.87%(P<0.01),体积减少了90.78%(P<0.01),容重增加了475.92%(P<0.01),含水量增加了20.15%(P<0.05);②当归果翅抑制了种子吸水吸胀的能力,果翅去除后能在2.48 h内进入稳定期,较去翅前提前了3.38 h,且吸水过程符合逻辑斯蒂方程; ③当归果翅对种子发芽具有显著影响,果翅去除后发芽势、发芽率和发芽指数较未去翅种子分别提高了256.7%、12.28%和27.77%,均达到了极显著水平(P<0.01)。当归双悬果去除果翅后,减小了种子体积和重量,并促进了种子吸水吸胀能力,同时还有效地提高了种子的发芽质量。建议在生产中以去翅种子作为播种材料进行播种。

Abstract:

The water absorption and germination process for intact and de-winged seeds(winged perianth removed) of Angelica sinensis were determined to provide a theoretical basis for its artificial propagation. With intact and de-winged seeds of A. sinensis, and intact seeds being used as a control group(CK), the 1000-grain weight, water content, volume, volume weight and water absorption ratio of seeds were measured, in the meanwhile, the germination test was proceeded under natural room temperature and in laboratory. Compare with CK, 1000-grain weight and volume of de-winged seeds decreased by 46.87% and 90.78%(P<0.01), respectively. The volume weight and water content of de-winged seeds increased by 475.92%(P<0.01) and 20.15%(P<0.05), respectively. The time ofwaterabsorption to reach stationary phase of de-winged seeds was 2.48 h, and was shorter than that of CK by 3.38 h, because the winged perianths significantly inhibited the waterabsorptioncapacity of seeds, and the soaking process fitted the logistic equation. Compared with CK, the germination potential, germination rate and germination index of de-winged seeds increased by 256.70%, 12.28% and 27.77%(P<0.01), respectively. The volume and weight of A. sinensis seeds were decreased, the water absorption capacity and germination quality of seeds were improve by removing winged perianths. Therefore, the de-winged seeds of A.sinensis should be applied in agricultural production.

Key words: Angelica sinensis, winged perianth, seed characteristics, water absorption rate, germination quality
