摘　　要：目的:探究几种典型野生百合在关中平原的适应性。方法:以卷丹百合、川百合和野百合为材料,对3种野生百合在关中平原的光合特征、水分利用效率、叶绿素含量、氮含量和生长情况进行了测定。结果:卷丹百合的净光合速率显著高于川百合和野百合,分别是川百合和野百合的1.76倍和1.41倍;卷丹百合水分利用效率>野百合>川百合,分别是野百合和川百合的1.20倍和1.68倍;3个百合品种间的蒸腾速率、胞间二氧化碳浓度和气孔导度没有显著差异;卷丹百合和野百合的叶绿素含量和氮含量显著高于川百合;卷丹百合的地上生物量显著高于川百合和野百合,分别是川百合和野百合的2.62倍和2.93倍。结论:隶属函数分析表明,3个野生百合品种综合表现排序为:卷丹百合>野百合>川百合。Objective:To reveal the adaptability of three wild lilies in Guanzhong Plain.Methods:Using the lilies reported in this study as materials,the photosynthetic gas exchange parameters,water use efficiency,chlorophyll content,leaf nitrogen content and growth of three wild lilies in Guanzhong Plain were measured.Results:The net photosynthesis of Lilium lancifolium was significantly higher than the other two varieties,which were 1.76 times and 1.41 times higher than Lilium davidii and Lilium brownii,respectively.The water use efficiency of L.lancifolium was 1.20 times and 1.68 times tigher than that of L.brownil and L.davidii.There was no significant difference in transpiration rate,intercellular carbon dioxide concentration and stomata conductance among three wild lilies.The chlorophyll content and leaf nitrogen content of L.lancifolium and L.brownii were significantly higher than L.davidii.The aboveground biomass of L.lancifolium was significantly higher than that of L.davidii and L.brownii,where were 2.62 times and 2.93 times higher than L.davidii and L.brownii,respectively.Conclusion:Subordinate function analysis was used to rank their comprehensive performance and the order was:L.lancifolium>L.brownii>L.davidii.
