摘要

本研究采用叶片几何形态计量学方法,定量分析了黑栎和黑栎的叶片形态差异。以及它们在塞尔维亚苏马迪加地区的数量。我们从8个种群中采集了2200片叶子,并在每片叶子上记录了13个地标。为了分析不同物种和种群的叶片形态差异,我们使用了Procrustes方差分析、双块偏最小二乘分析、主成分分析和典型变量分析。结果表明,种间存在明显的差异,其次是不同程度的叶片形状变异。与小叶扁桃相比,小叶扁桃叶片表现出更高的变异水平和群体间的差异。两种的种群分组模式差异很大,表明不同的因素导致了种内变异。本研究提供了塞尔维亚苏马迪加地区栎树树种叶片形态变异的初步结果。未来的研究应包括遗传和环境分析,以了解物种和种群之间表型差异的起源,并充分认识哪些因素主要决定了分类群之间的关系。

Inter- and intraspecific variability of Quercus cerris L. and Quercus frainneto Ten. in the Sumadija region (Serbia) based on leaf geometric morphometrics
In this study, we used leaf geometric morphometrics to quantify the differences among Quercus cerris L. and Quercus frainetto Ten. and their populations in the Sumadija region in Serbia. We sampled 2200 leaves from eight populations and on each leaf recorded 13 landmarks. To analyze how leaf morphology varies across species and populations, we used Procrustes ANOVA, a two-block partial least-squares analysis, a principal component analysis and a canonical variate analysis. The results showed a clear discrimination between species, followed by different levels of leaf shape variability in Q. cerris and Q. frainetto. The leaves of Q. cerris displayed higher levels of variability and higher differences among populations compared to Q. frainetto. The patterns of population grouping in the two species greatly differed, indicating that in these species different factors contribute to intraspecific variability. This study provides preliminary results of the leaf morphometric variability of oak species in the Sumadija region in Serbia. Future studies should include genetic and environmental analyses to understand the origins of phenotypic differences between species and populations, and to fully recognize which factors mostly determine relationships between taxa.
