摘要：

为了揭示氯化镧对潍县萝卜陈种子活力的影响，以潍县萝卜陈种子为试材，对其进行不同时间、不同浓度氯化镧浸种处理，测定种子的发芽率、发芽势、发芽指数和活力指数。结果表明：0~10 mg/L氯化镧溶液浸种12 h和24 h，潍县萝卜种子发芽率、发芽势、发芽指数均比CK显著提高，而活力指数仅有浸种12 h得以显著提高。0~10 mg/L氯化镧浸种36 h和48 h，种子发芽率、发芽势、发芽指数都比CK有不同程度的降低，活力指数则略有升高，但都未达到显著水平。因此，在生产中可以用2.5 mg/L氯化镧溶液对潍县萝卜陈种子浸种12 h，即起到经济、有效提高种子活力的目的。

Abstract:

To reveal the influence of Lanthanum on the seed vigor of Weixian Radish, the effects of Lanthanum in different concentration and different treating time on vigor of Weixian radish’s old seeds were researched, and germination energy, germination rate, germination index, and vigor index was tested. The results showed that germination energy, germination rate, and germination index was increased significantly by soaking seeds in 0-10 mg/L LaCl3 for 12 h or 24 h. However, vigor index was increased significantly only by soaking seeds for 12 h. When soaking seeds in 0-10 mg/L LaCl3 for 36 h or 48 h, germination energy, germination rate, and germination index was decreased and vigor index was increased a little. However, the difference between the control and the treated was not significant. The Weixian radish old seeds were soaked in 2.5 mg/L LaCl3 for 12 h was optimal for improving seed vigor in practice.
