Abstract
The effect of a brief exposure to treatments of end-of-day (EOD) far-red (FR) light and EOD-heating on flowering and stem elongation in certain species cultivated in areas with limited sunshine from autumn to winter has been investigated. Thirteen EOD-FR treated cultivars among all 24 cultivars tested in experiment 1, showed earlier flowering than control plants. Additionally, Kanzaki No.21, F1 Winter cherry and Gypsy deep rose were earlier to flower under the all night-FR treatment than under the EOD-FR treatment. Further, 13 cultivars among all cultivars tested in experiment 1 showed greater stem length, whereas 16 cultivars of them showed greater mean internode length than controls when treated with EOD-FR. The days to flowering in 13 cultivars treated by EOD-Heating, flowering was earlier than in controls. Also, stem length and mean internode length were also promoted by the same treatment in 7 cultivars. Additionally, flowering and stem elongation of Stella rose, Arizona sun, Suzuhime and Extra carmine rose were promoted by a combination of both treatments, and productivity and quality were improved. These results suggest that the treatments tested can help the production of cut-flowers in areas with limited sunshine from autumn to winter, although the method of application of the treatments must be optimized for each species.
期刊介绍:
The journal publishes results of basic and applied research from all areas of horticulture, fruit-growing, vegetable-growing, wine-making and viticulture, floriculture, ornamental gardening, garden and landscape architecture, concerning plants that are grown under the conditions of European temperate zone, or field plants that are considered as horticultural cultures. Original scientific papers, short communications and review articles are published in the journal. Papers are published in English (British spelling).
