22种百合属植物在青岛地区引种的适应性研究

为丰富青岛地区能够利用的百合属植物的优良种类,以荷兰引进的22个百合属植物品种为试材,对其在青岛地区的引种适应性进行研究,系统观测不同品系百合品种的物候期、生长规律、花部特征和花色参数等。结果表明,22个百合品种均能适应青岛地区的环境条件,不同品系百合花期集中在5月,亚洲百合杂种系Lilium asiatica hybrids（AH杂种系）]、麝香百合杂种系L. longiflorum hybrids（LH杂种系）]和麝香百合和亚洲百合杂种系间的杂交种L. longiflorum× asiatic hybrids（LA杂种系）]平均单花花期分别为9.25、12.43、14.43天。不同品系百合株高随时间的延长而呈逐渐增高的趋势,但不同品系间增高幅度不同。不同品系百合品种花径、花苞数目和花量不同,LH杂种系的花径和花苞数目小于AH杂种系和LA杂种系。花色参数中,AH杂种系的明度参数L*低于其他品系,LH杂种系中‘Regale’红绿参数a*值最低,为-2.08,LH杂种系中‘Dancing girl’黄蓝参数b*值最低,为-4.61。研究结果明确了百合属植物在青岛地区的引种适应性,为进一步的合理开发利用提供理论依据。

Introduction and Analysis of 22 Lilium Hybrids in Qingdao

This paper aims to enrich Lilium species that can be fully utilized in Qingdao. 22 Lilium hybrids, introduced from Holland, are used as materials, the plant phenological phase, dynamic growth performance, characteristics of flower phenotype, and flower color parameter are investigated for the planting adaptability of the varieties in Qingdao. The results show that all the 22 Lilium hybrids adapt well to the environmental conditions of Qingdao. The flowering stages of the Lilium hybrids mainly concentrate in the middle of May. The single flowering stage of Lilium asiatica hybrids, L. longiflorum hybrids, and L. longiflorum×asiatic hybrids is 9.25, 12.43 and 14.43 d, respectively. In addition, the plant height of Lilium hybrids increases with the time, while different kinds of Lilium hybrids show different degrees of increasing trend. Moreover, the inflorescence diameter, the number of flowers and inflorescence vary among different kinds of Lilium hybrids. The inflorescence diameter and the number of flowers in L. longiflorum hybrids are smaller than those of L. asiatica hybrids and L. longiflorum× asiatic hybrids. The flower color parameter L ^* of Lilium asiatica hybrids is lower than that of L. longiflorum hybrids and L. longiflorum× asiatic hybrids. Among the L. longiflorum hybrids hybrid lines, the red-green parameter of ‘Regale’ has the lowest a ^* value of -2.08, and the yellow-blue parameter b ^* of ‘Dancing girl’ has the lowest value of -4.61. The above results clearly illustrate the performance of the introduced Lilium hybrids in Qingdao, and could provide the foundation for further utilization of Lilium species in the near future.
