Polyamine titer in the leaves of the self-seedlings of Doritis pulcherrima Lindley¡]cv. S84-3352¡^under short-day ( SD, 9 hours of light period ) and long-day ( LD, 16 hours of light period ) exposures were determined. A significant reduction in acid insoluble spermidine levels occurred in D. pulcherrima leaves after 30 days of SD compared to the LD exposures. After 30 days of SD there was a transient decrease in acid insoluble spermidine and an increase in acid insoluble spermine in the leaves. When the flowering shoot reached 7 -10 cm long ( with flower primordia in SD ), free cadaverine, acid insoluble putrescine, and spermine levels were higher than those in 2-3 cm flowering shoot ( with no flower primordium derived from SD ) These results suggest that polyamines are implicated differently during photoperiodic flower induction and flower devlopment in D. pulcherrima.
