Fig. 7From: Elucidation of molecular and hormonal background of early growth cessation and endodormancy induction in two contrasting Populus hybrid cultivarsTop four contributing components of the PCA analysis are Ox-IAA, Phaseic Acid, DAM1, cis-zeatin riboside-O-glucoside (cZROG), accounting for 26.6, 23.3, 12.3 and 9.9% of the variation, respectively. Each component is plotted in the function of the other three components after standardization. The color saturation with the markers size indicates the sampling time of the poplar cultivars, between 0 and 60 days. Filled triangles and circles show the results obtained for Walker and Okanese cultivars, respectivelyBack to article page
