[Abstract]  Leaf morphometrics are used frequently by several disciplines, including taxonomists, systematists, developmental biologists, morphologists, agronomists, and plant breeders to name just a few. Leaf shape is highly variable and can be used for identifying species or genotypes, developmental patterning within and among individuals, assessing plant health, and measuring environmental impacts on plant phenotype. Traditional leaf morphometrics requires hand tools and access to specimens, but modern efforts to digitize botanical collections make digital morphometrics a readily accessible and scientifically rigorous option. Here we provide detailed instructions for performing some of the most informative digital geometric morphometric analyses available: generalized Procrustes analysis, ... [摘要]  叶子形态测量经常被几个学科使用,包括分类学家,系统学家,发育生物学家,形态学家,农艺学家和植物育种者,仅举几例。叶片形状高度可变,可用于鉴定物种或基因型,个体内和个体之间的发育模式,评估植物健康以及测量对植物表型的环境影响。传统的叶子形态测量需要手工工具和标本,但现代化的数字化植物收藏的努力使数字形态测量学成为一种易于获取和科学严谨的选择。在这里,我们提供详细的说明,用于执行一些最有信息的数字几何形态测量分析:广义Procrustes分析,椭圆傅里叶分析和形状特征。叶面形状分析的综合程序由六个主要部分组成:A)材料扫描,B)获取地标,C)地标数据分析,D)隔离叶轮廓,E)叶轮廓线分析,F)形状特征。该协议提供了一个详细的参考,用于将边界和轮廓分析应用于叶子形状以及描述叶子形状特征,从而使研究人员能够为不同应用执行高吞吐量表型分析。

背景 数字叶形态测量方法有各种方法,包括轮廓或傅里叶分析,轮廓特征,地标分析,形状特征,分形维数和纹理分析(Cope等人,2012)。在这些分析中,地标和傅立叶分析在叶片形状之间的区分中表现非常好(McLellan和Endler,1998; ...
