Abstract
KODA (9-hydroxy-10-oxo-12(Z),15(Z)-octadecadienoic acid) has been found as a factor involved in the flower-induction of Lemna paucicostata [Plant Cell Physiol 41: 110-113 (2000), ibid 42: 1201-1209 (2001)]. The change of endogenous KODA in dark period was closely correlated with the flower-induction in Pharbitis nil. [ibid 44: 35-43 (2003)].<br> Here, the frequency distribution of the number of flower buds induced with various dark lengths demonstrated a bimodal pattern with a cove at the number of three-flower buds. When the flower number was under three in average, there was only a peak. Then, upon KODA-treatment, the peak became a bimodal pattern: KODA promoted the flower-induction. No KODA activity was found, when it was applied on the seedlings for allowing the flower number to be over three. In the structural specificity test, either a structural isomer or a stereoisomer showed no activity. All data suggest that KODA take an important role in the flower-induction.
