Stockplants with various physiological characteristics were compared in a propagation experiment with leafy cuttings of ornamental cherry Prunus subhirtella ‘Autumnalis’. At the time of severance, cuttings harvested from juvenile 3-year-old in vitro-derived plants contained in their bases nearly twice as much IAA (indole-3-acetic acid) as cuttings derived from mature 40-year-old trees. Juvenile cuttings showed better rooting success in the propagation season. They developed a significantly higher number of primary roots and grew better than physiologically older cuttings. IAA time-course levels in cutting bases in the days after severance were similar in both cuttings types. They decreased over the first day (rooting late initiation phase) after severance until the third day after severance when the levels increased again (rooting induction phase and beginning of the root developing phase). At the time of severance, juvenile cuttings also contained higher concentrations of IAAasp (indole-3-acetyl aspartic acid) in their bases than mature cuttings. IAAasp time-course levels were similar to those measured for IAA.
