Checking was done by using four separate rooms equipped for artificial climate control. 1. Only a low temperature plot under the short day length showed normal height of stem length, however the other plots include long day length showed succulent growth or longer stem. 2. Numbers of leaves also showed same tendency that the leaves increased under the heigh tempeature and long day length. 3. Plots under the short day length on 3 lower temperatures showed about 60 days untilflowering, but the other all plots under the long day and high temperature under the short day length showed more than 90 days. 4. The balance of inflorescence as spray type flower were poor at the plotsexcept low temperature and short day length. 5. Clitical day length of cv. Honey might be exist at longer point than 15 hours due to all plants flowered in these experiment plots., 論文}, pages = {17--21}, title = {スプレーギクの発育と日長、温度の組み合わせ}, volume = {31}, year = {1996} }
