Effect of DHAP on seedlings growth of <i>P</i>. <i>schrenkiana</i>.

<p>a: Radicle elongation. b: Fresh weight. <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).
