Use of light, carbon dioxide enrichment and growth regulators in the overwintering of hardy ornamental nursery stock cuttings

, : Use of light, carbon dioxide enrichment and growth regulators in the overwintering of hardy ornamental nursery stock cuttings. Acta Horticulturae (54): 105-116

Softwood cuttings of a range of deciduous ornamental shrubs were taken in July and August (except for azalea cuttings, taken in April) and subjected to treatments with GA3 (plus other growth substances in some cases), extended photoperiod and supplementary CO2. With Betula pendula the provision of dusk-to-dawn low intensity lighting increased budbreak and leaf retention and improved plant size and leaf growth; these effects were enhanced if supplementary CO2 was also given.

Some results of 2 years' trials with Polygonum, Cotinus, Corylus, Syringa, Viburnum and Elaeagnus spp., cvs or hybrids, are presented. Etiolation was not as successful as with M.9 apple rootstock but it showed promise for Syringa.
