The influence of snagging methods on the growth of roses in a nursery trial : A thesis submitted to the Royal New Zealand Institute of Horticulture for the National Diploma in Horticulture

Abstract

Following normal budding in January an Rosa muliflora rootstocks several snagging methods were compared in a nursery trial in Hawke's Bay. There were no significant differences in plant size between treatments. The traditional method of removing stock growth, four months after budding, produced the most satisfactory results. Treatments had less effect on plant size than scion varieties. Economic aspects of' rose bush production re discussed and normal treatments most profitable. The incidence of virus disease interfered with the interpretation of this experiment. The use of virus free budwood and rootstocks is recommended and is an important factor affecting the profitability of rose plant production in New Zealand nurseries.
