摘要:

为探究伊犁郁金香自然分布居群花色表型多样性,利用色差仪对自然分布的23个伊犁郁金香居群315个个体进行花色表型值测定,利用单因素方差分析、聚类分析、相关分析等方法研究不同居群的花色表型多样性。结果表明:伊犁郁金香不同居群之间花色明度值(L*)、红度值(a*)、黄度值(b*)、彩度值(C*)、色调角(h)均有不同程度的变化,且部分居群之间差异较大,23个居群的L*介于45.64~67.19之间,主要为中等明度;a*变化范围为2.43~14.95,花色偏红色且红色强度为低红度;b*变化范围为19.13~40.83,花色偏黄色且黄色强度为低中黄度;C*变化范围为25.88~43.50,饱和度等级为中高饱和度;h变化范围为24.82~78.27,颜色类型为红色、橙红色和橙黄色。23个居群的聚类分析结果显示,在欧氏平均距离为5时可划分为3个类群,类群Ⅰ、Ⅱ均有10个居群,占比均为43.48%。其中类群Ⅱ的10个居群花色以橙色系为主,类群Ⅲ仅有花色变异较大的3个居群(BDW、BSF、NLT),占比为13.04%,花色以橙红色为主。不同居群花色性状与地理因子之间的相关性分析表明L*b*C*h与纬度均呈极显著正相关,L*a*b*C*h与海拔和经度无显著相关性。该研究证实,在纬度的影响下,采样区内伊犁郁金香自然居群花色表型具有多样性,存在丰富的花色变异。

Abstract:

To investigate the flower color phenotypic diversity of natural Tulipa iliensis populations, flower color phenotypic values were measured using a colorimeter for 315 individuals from 23 natural populations. One-way ANOVA, cluster analysis and correlation analysis were used to examine flower color phenotypic diversity across populations. Results showed that the values of lightness (L*), redness (a*), yellowness (b*), chroma (C*) and hue angle (h) varied to different extents among populations, with considerable differences observed between some populations. Across the 23 populations, L* ranged from 45.64 to 67.19, mainly indicating medium lightness; a* ranged from 2.43 to 14.95, biased towards red with low redness intensity; b* ranged from 19.13 to 40.83, biased towards yellow with low-to-medium yellowness intensity; C* ranged from 25.88 to 43.50, belonging to the medium-to-high saturation level; and h ranged from 24.82 to 78.27, corresponding to red, orange-red, and orange-yellow color types. Cluster analysis indicated that at a Euclidean average distance of 5, the 23 populations could be divided into three groups. Groups Ⅰ and Ⅱ each contained 10 populations(43.48% each), with the flower color of Group Ⅱ predominantly orange. Group Ⅲ comprised three populations (BDW, BSF and NLT), accounting for 13.04%, exhibiting substantial flower color variation and dominated by orange-red. Correlation analysis between flower color traits and geographic factors revealed that L*, b*, C* and h were highly significantly positively correlated with latitude, whereas no significant correlations were found between L*, a*, b*, C*, h and either altitude or longitude. This study confirmed that under the influence of latitude, flower color phenotypes of natural T. iliensis populations within the sampling area are diverse, exhibiting rich variation.
