Factors involved in the propagation of rhododendron from cuttings

, : Factors involved in the propagation of rhododendron from cuttings. Acta Horticulturae (79): 89-92

The results are presented of trials on rooting cuttings of large-flowered rhododendron cvs, involving wounding, growth substance and temperature treatments. The cuttings were taken in late autumn/early winter. With 6 cvs tested, wounding on both sides of the cutting resulted in more losses than a conventional single wound or a chip wound, although rooting percentages were similar for the 3 methods. Cuttings of the Britannia were treated with 0.8%, 2%, 10% or 4000 p.p.m.
