Abstract

|
|
|
The polyamine and its biosynthetic enzyme In ginseng has been studied , We have found that putrescine was a major polyamine in ginseng seedling. Putrescine was increased with growth stage , and ADC activity was also increased as putnescine content. But ODC activity was not shown. ADC activity was shown l0% inhibition by spermidine and 20% inhibition by spermine but not affected by putrescine. in contrast to seed, spermidine was a major polyamine in two year old ginseng. The abundance was decreased in order of leaf, petiole, root, and stem. ADC activity seemed to parallel with polyamine content.
