DOIAbstract
<p>The factor loading values for variables are indicated by red arrows radiating from the centre showing the direction (angle) and magnitude (length). Numbers indicate classification of 37 genotypes based on the factor scores of PC1 and PC2 (A) and PC3 and PC4 (B) principal components (<a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0129520#pone.0129520.s012" target="_blank">S1 Table</a>). Legend for variables: SL, shoot length; RL, root length; SDW, shoot dry weight; RDW, root dry weight; TBM, total biomass; RSR, root-to-shoot ratio; LA, leaf area; CHL A, chlorophyll a; CHL B, chlorophyll b; PN, photosynthesis; SPCONC, shoot P concentration; RPCONC, root P concentration; TPU, total P uptake; PUE, P use efficiency; AP,...
