Abstract

The effects of different nitrogenous fertilizer on carbon metabolism in Glehnia littoralis were studied under the field condition. The results showed that the Sucrose Phosphat Synthase (SPS) activities and the content of soluble sugar in leaves showed the pattern of single peak curve during the growth period, and both highest level were similary appeared in the middle stage. The suitable rate of nitrogenous fertilizer can improve the SPS activities, the content of soluble sugar, the root Sucrose Synthase (SS) activities, and also kept low level of leaves soluble sugar in harvest. So it can be supply sufficient for assimilation of polysaccharide in the root as well as to increase the yield.
