Abstract

As garden-type cyclamens are intolerant to high temperature or strong irradiation, their growth is stunted under such conditions during the summer season in southwest Japan. Evaporative cooling from the surface of compacted medium without polyethylene pot is expected to enhance the growth of garden-type cyclamens. The effects of polyethylene pot removal and irrigation method on growth and flowering of garden-type cyclamen during the summer season were investigated. Water was supplied by wick irrigation, ebb and flow irrigation (once a day) and overhead irrigation from 25 July to 4 September. From half of the plants in each treatment, polyethylene pots were removed from compacted media. Maximum, minimum and average temperatures of compacted medium without polyethylene pot decreased significantly compared to that of compacted medium with polyethylene pot. The medium temperature of the wick irrigation with polyethylene pot was highest. However, the temperature differences among irrigation methods without polyethylene pot were slight. The leaf temperature of plants grown in compacted medium without polyethylene decreased significantly compared to that with polyethylene pot. At planting, total fresh weight, leaf number and bud number of plants grown on compacted medium without polyethylene pot were significantly higher than those with polyethylene pot. However, there was no difference with regard to tuber weight and size among treatments. Subsequent growth after planting showed the same tendency as the size at planting. These results suggest that in garden-type cyclamen production during summer season, evaporative cooling by compacted medium without polyethylene pot may decrease medium and plant temperature, thus, plant growth may be enhanced.
