KODA has been found as a stress-induced factor that related to the flower-induction of Lemna paucicostata. KODA also has been unveiled to be a flowering promoter for various kinds of garden plants. Here we report the features of the flower-promoting effects of KODA. We examined the flower-promoting effects of KODA by using 24 species including 57 varieties, mainly many varieties in Dianthus caryophyllus (carnation) and Cyclamen percicum (cyclamen). The effects varied depending on cultivation manners. When KODA worked, it could not only advance the date of the flowering but also increase the total number of flowers during the experiment. There was a clear difference in the effect of KODA between the late-flowering and early-flowering varieties. For example, in Lavandula angustifolia (lavender) and Eustoma russellianum (prairie gentian) could be effective and ineffective in the late-and early-flowering varieties, respectively. In the result, KODA can show a clear flower-promoting effect on plants depending the cultivating condition, regardless of species including long-day plants (D. caryophyllus, etc), short-day plants (Pharbitis nil, etc), and low-temperature-flower-inducing plants (L. angustifolia, etc). The part of this research project has been supported by a grant-in-aid from The Research and Development Program for New Bioindustry Initiatives.
