3种野生百合在榆中地区的引种表现

Introduction of Three Wild Lilium Species in Yuzhong Area

在兰州榆中地区对野生兰州百合、大花卷丹、王百合的适应性进行研究。结果表明,3个野生百合品种均能适应榆中地区的环境条件,但生长周期存在差异,为174~226 d。王百合花型大、柱头长、植株高、茎粗、叶多;大花卷丹花型、花形等花性状与王百合相似,但自身结实率较高,采收后产量增长率较高;兰州百合花型小、柱头短、采后母籽个数,但母籽周径小于大花卷丹。可利用各自的优良性状进行新品种选育。

The adaptability of Lilium davidii,Lilium leichtlinii var.maximowiczii、Lilium regale in Yuzhong area of Lanzhou was studied.The results showed that three wild Lilium species all adapted well to the environmental conditions in Yuzhong area,but their growth cycles were different,ranging from 174 to 226 days.Among them,Lilium regalis had the advantages of the large flower type,long stigma,high plant height,thick stem and multiple lobes;The flower type and shape of Lilium leichtlinii var.maximowiczii were similar to those of Lilium regale,but the seed setting rate was higher,and the yield growth rate after harvest was significantly higher than that of the other two varieties.Lilium davidii had the small flower type,short stigma and large number of mother seeds after harvest,but the circumference of mother seeds was significantly smaller than that of Lilium leichtlinii var.maximowiczii.New cultivars can be selected and bred according to their superior characters.
