Exogenous melatonin promoted seed hypocotyl germination of <i>Paeonia ostia</i> ‘Fengdan’ characterized by regulating hormones and starches
Correlation analysis established that 100 µM MEL pretreatment most effectively improved the rooting rate characterized by increasing <i>α</i>-amylase activity to facilitate starch decomposition, boosting GA<sub>3</sub> levels, inhibiting ABA production to increase the relative ratio of GA<sub>3</sub> to ABA. Moreover, MEL increased radicle thickness of peony seeds correlating with promoting starch decomposition and enhancing the synthesis of GA<sub>1</sub> and GA<sub>7</sub>.
