百合属植物种子发芽试验研究

Study on Seed Germination of Lilium L.

对8种百合属植物的种子性状和发芽特性进行了试验研究。结果表明,仅毛百合属于地下子叶类型,朝鲜百合、垂花百合、有斑百合、大花卷丹、细叶百合、麝香百合杂种系品种罗瑞拉、亚洲百合杂种系品种布鲁拉诺均属于地上子叶类型。有斑百合、大花卷丹、朝鲜百合、细叶百合、罗瑞拉和布鲁拉诺种子发芽率高,其中罗瑞拉发芽率最高,达91%。毛百合和垂花百合种子发芽率低,低于20%,其中毛百合发芽率仅8.8%。有斑百合种子储藏2a后其发芽率仍较高,可高达92%。

Characteristics of seed and its germination in Lilium was investigated in the paper. The results showed that only the seed of L. dauricum Ker. -Gawl. belong to the type of underground cotyledon, and the other species, L. amabile Palib, L. cernum Kom., L. concolor var. buschianum Baker, L. rum hybrids cv. Lorina, and Asiatic hybrids cv. Brunello, leichtlinii var. maximowiczii Baker, L. pumilwn DC. , Longiflo- belong to the type of overground cotyledon. The rates of germination of L. concolor var. buschianum Baker, L. leichtlinii vat. maximowiczii Baker, L. amabile Palib, L. pumilum De., Longiflorum hybrids cv. Lorina, and Asiatic hybrids cv. Brunello were higher, with the highest of 91% in Longiflorum hybrids cv. Lorina. The rates gemlination of L. dauricum Ker.-Gawl. and L. cernum Kom. were lower, with less than 20%, and the rate of germination of L. dauricum Ker. -Crawl. was lowest, with 8. 8% only. The rate of germination and vigor of gemaination of L. concolor var. buschianum Baker was still higher after its seeds were stored for two years.
