Fig. 7From: The transcriptional events and their relationship to physiological changes during poplar seed germination and post-germinationAnalysis of changes in physiological parameters related to primary metabolism. (a–h) Changes in total protein content (a), free amino acid content (b), starch content (c) soluble sugar content (d), DNA content (e), RNA content (f), respiratory rate (g) and free fatty acid content (h) during poplar seed germination. In each plot, bars labelled with different lowercase letters are significantly differentBack to article page
