摘要：

Extracts from the cotyledons of seedlings of Pharbitis nil strain 'Violet' cultured at low temperature, which induces their flowering even in continuous light, with or without precedent exposure to high-intensity light, which shortens the period of low temperature required for flowering, were analyzed by HPLC for substances correlating with the flower-inducing process. The content of two phenylpropanoids were found to increase during the low-temperature, and were identified as 3-O-feruloylquinic acid and dehydrodiconiferyl alcohol-13-O-beta-D-glucoside. The increase was more rapid in the cotyledons exposed to high-intensity light before the low-temperature. This suggests that the accumulation of these compounds is correlated to the promotive effect of high-intensity light on the flower-induction by low temperature.
