Abstract
|
|
|
This study was conducted to find out the variation modes of the absorbtion contents of N, P and K and the contents of decursin, decursinol and sugar in Angelica gigas Nakai at different growth stages. The results of field study were as follows.
The dried weights of root and shoot was increased by the application of nitrogen and potassium fertilizers during the growing seasons. But, the effect of phosphorus application was observed only the increasing of the dried weight of shoot. During the growing seasons, the contents of nitrogen and phosphorus in root was decreased, but in shoot was increased. The potassium contents of root was increased and that of shoot was decreased. The decursin and total sugar contents of root were continually increased, and the decursinol and reducing sugar contents were increased until the middle growth stage and after that were decreased.
