Principal components analysis (PCA) for morphological (a) and molecular variation (c: genetic; d: epigenetic), and (b) canonical correspondence analysis (CCA) for environmental variables and cytotype distribution of <i>Actinidia chinensis</i>.

Abstract

<p>PCAs (a, c and d) only present the first two principal components and ellipses represent the dispersion of those points around their center. Abbreviations in PCA analysis of morphological variation are given in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0117596#pone.0117596.s002" target="_blank">S2 Table</a> and abbreviations in CCA analysis are given in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0117596#pone.0117596.t001" target="_blank">Table 1</a>.</p
