Characteristics of fruiting shoots of four species of hip roses for use in floral arrangements
Woody cuts are portions of woody ornamentals used for floral or decorative purposes. Some species of wild roses, because of the decorative fruits (hips) can be used for this purpose. The aim of this study was to evaluate the usefulness of Rosa Carolina, R. filipes, R. multiflora and R. virginiana for commercial growing of cut branches for floral arrangements. To assess flower bud formation and fruit production on the current or previous wood, half of the plants in the experiment were pruned annually to a height of 10 cm. Production data regarding shoots length, yields and decorative value for four Rosa species are presented over a three-year study. The most decorative shoots with hips were produced by unpruned R. multiflora shrubs, which had the most uniformly coloured red fruits (an average of 20 on a single shoot), and the hips were small (0.3 g). The fruits were mainly on the lateral shoots, whose average length was 22 cm. This species is also distinguished by a very small number of spines on the shoots, with some shoots completely free of spines, which is a very advantageous feature for using R. multiflora in floral arrangements. Yield and morphological characteristics of the fruit-bearing shoots of R. filipes were similar to those of R. multiflora, but the yields in the individual years of this study were different, and the colouring of the fruits in clusters was greatly extended in time. Unpruned shrubs of R. Carolina and R. virginiana produced 2-3 times fewer fruit-bearing shoots, with larger fruit, than R. multiflora. The treatment of the annual autumn pruning adversely affected flowering and fruiting of each species of rose.
