The growth and quality of cut flowers of chrysanthemum (Dendranthema grandiflora cv. Syuho-no-chikara) were compared among various types of hydroponic systems during June to October. The systems were 1) capillary mat/drainage (CM/D), 2) capillary mat/recycling (CM/R), 3) deep flow technique/intermittent circulation (DFT/IC), and 4) deep flow technique / continuous circulation (DFT/CC) . The same concentration of the nutrient solution was supplied to the four hydroponic systems. Soil culture was designated as a control. The stem length and flower diameter in the CM/D and DFT/IC systems were the same as those in the control, while the stem diameter in those systems was larger than the control. In the DFT/CC systems, plants with the least height and the weakest stem were produced. The vase life of cut flowers was almost equal in the two CM systems and the control, while it was shorter in the two DFT systems. The poor growth in the DFT/CC system would not be due to the deficiency of dissolved oxygen, but to the undesirable rise of solution temperature in the summer season. These results show that a higher quality of chrysanthemum can be produced in the capillary mat system than in the DFT system.
