Traditionally, rose coltivation has relied upon labor-intensive measures and the production costs has been rising up steadily. THis make the needs for more efficient methods of rose cultivation especally in western europe, america, and japan. One of the earlier developments in the cultivation technology was the year-round production system in greenhouse and the introduction of automation has been the latest one.
The automation of cut rose production has been possible primarily through two important factors. First, the self-rooted, single-stemmed plants raised from single-node cuttings, an alternative to the multi-stemmed rose cultivation, enabled the production of large numberes of uniform shoots per unit area in short cultivation cycles. Secound, the cultivation area restliction imposed by greenhouses accelerated the establishment of high-density cultivation methods. This study was conducted to confirm the optimum methods for single-stemmed culture of cut roses which are suitable to korean environmental factors and traditional cultural methods.
The results are summarized as follows:
1. Study for the production of high quality cuttings.
The cuttings, both 'Nobleless' and 'Red Velvet', were propagated up to 100% with Rootone treatment, while less than 100% with other growth promoter treatments. In 'Red Velvet', propagation rate increased with increasing IAA, NAA, and IBA concentrations. But in 'Nobleless', the rate increased up to 500ppm in NAA and IBA, and 1000ppm in IAA, and then decreased above the concentrations. In 'Nobeless', root number, length and weight increased by Rootone treatment. But in 'Red Velvet', root number and length increased by IBA treatment, while root weight was heaviest in Rootone treatment.
The propagation rate was highest in peatmoss(P) and coarse vermiculite(CV) mixture(1:2). In 'Little Mable' and 'Suplesse', the rate was above 95%, and the other cultivars showed 100% propagation rate. 'Rote Rose' showed lowest propagation rate, but in the composition, the rate was 100%. In the composition, root growth was accelerated. Root number, root weigtht and root diameter increased in P:CV(1:2) mixture But root length icreased in peatmoss and perlite(PE) mixture(1:2) And the cuttings which were propagated in the media showed the best growth after transplanting.
To clarify the optimum density, three types of plug trays, 200, 128, and 50 holes per tray, were used in this study, The best results for propagation of roses occurred in 50 hole tray.
2. Effect of environmental factors affecting the singled-stemmed culture of cut roses.
Propagation was accelerated and the rate increased under high light intensity, and root growth increased also. Between both cultivars, propagation and root growth of 'Red Velvet' decreased dramatically with decreasing light intensity.
During summer, root growth of cuttings accelerated by the mist treatment which was sprayed 20 second per hour during daytime. The mist treatment also accelerated the growth and flowering of rose, finally enhanced the quality of cut flowers. Carbon dioxide fertilization was effective to enhance the growth and flowering of roses.
3. Study for year-round culture of singled-stemmed roses.
Propagation and root growth of 'Red Velvet', 'Nobleless' and 'Supress' was accelerated by fertilization with 0.6X solution from 2 weeks after cutting, while in 'Sweetness', 0.4X solution was most effective in propagation and root growth.
Plant growth was accelerated by increasing nutrient solution concentrations up to 0.6X, but the growth was the lowest at 0.8X, highest concentration. Stem length, total nodes at visible flower bud and stem length were slightly increased at harvest. Internode length and five-leaflet leaves were not significantly influenced by the treatment. Fresh weight was increased by increasing concentrations up to 0.6X. Flower bud width, flower neck length and stem diameter was not significantly affected by the treatment.
The nitrate contents decreased in low concentrations, such as control, 0.05X, 0.2X, and 0.4X. At high concentrations, the level was remained at the same level at transplanting. The potassium contents decreased in low concentrations, such as cont., 0.05X, and 0.2X. At high concentrations, such as 0.6X and 0.8X, potassium contents decreased until 13th days after transplanting, and then increased. From 13th davs after transplanting, the level was remained at the same level in 0.4X concentration. The calcium contents decreased in low concentrations, such as control, 0.05X, and 0.2X. At high concentrations, such as 0.8X rapidly calcium contents increased from 20th days after transplanting. Calcium contents were remained constantly between 0.4X and 0.6X. The magnesium contents decreased in all treatment and then at high concentrations, such as 0.6X and 0.8X were increased from 27th days after transplanting. however, at low dilution levels, such as cont., 0.05X and 0.2X magnesium contents were decreased after 27 the days. During high density single-stemmed culture of rose, nitrogen content i leaves increased during vegetative growth stage. From visible flower bud stage, the content decreased to harvest stage. Potassium and magnesium content also inceased during vegetative stage, and decreased from visible flower bud stage. But calcium content in leaves increased gradually throughout the experiment.
