Effect of DHAP on seed germination of <i>P</i>. <i>schrenkiana</i>.

<p>a: Germination rate. b: Germination vigor. 1: 0.1 mM. 2: 0.25 mM. 3: 0.5 mM. 4: 1.0 mM. <i>Error bars</i> present standard errors of five independent biological replicates. The same upper- and lower-case letter indicates a non-significant difference (<i>p</i> > 0.05), different lower-case letters indicate a significant difference (<i>p</i><0.05), different upper-case letters indicate a strongly significant difference (<i>p</i><0.01).
