For the large-flowered chrysanthemums (<I>Dendranthema grandiflorum</I> (Ramat.) Kitamura) of the summer-to-autumn-flowering type, cut flower production using cold treatment and ethephon sprays without light control under open field conditions, was studied in Kenya and in Japan during the summer (similar climatic conditions as in Kenya) . For the cultivars grown in Japan, the number of days from planting to flowering, leaf number and stem length increased when sprays of 200 mg/l ethephon were used, compared with the controls in Kenya. In 'Seiun' chrysanthemums, the number of days from planting of flowering was the higher after three ethephon sprays while in 'Summer-yellow' chrysanthemums, after five ethephon sprays the highest number of leaves in both cultivars was observed after four ethephon sprays. In both cultivars, the weight of the cut flowers and the diameter of the stems increased when three and four sprays of 200 mg/l ethephon were used, respectively and the number of internodes was twice as low as that of the controls. In both cultivars, the stem was 60 % longer than that of the control. Synergistic elongat in was achieved by using a combination of ethephon sprays and cold storage of the mother stocks for one month under open field conditions. The stem of 'Seiun'during the summer in Japan was longest with the application of 200 mg/l ethephon, that of 'Summer-yellow' with 600 mg/l and that of 'Super-yellow'with, 1, 000 mg/l in the last period of sprays. However, the stem was still too short for the Japanese cut flower market, since the stem of flowers in high class category should be more than 80 cm long.
