Fig. 4From: The transcriptional events and their relationship to physiological changes during poplar seed germination and post-germinationChanges in the activity of primary metabolism-related genes during poplar seed germination. The x-axis labels 1–5 are 0.75 h vs. 0 h, 6 h vs. 0 h, 24 h vs. 0 h, 48 h vs. 0 h and 144 h vs. 0 h, respectively, and the y-axis corresponds to ΣZ valuesBack to article page
