Separation and purifcation of shikimic acid from Picea meyeri with ion exchange resin

The variation in ring growth indices of Picea meyeri was assessed by dendrochronological techniques including response functions, correlation functions and single-year analysis on sandy dunes in the Xilin River basin steppe.

For the clarifying the effect of pertinence between the CO2 concentration double or temperature elevating in different nitrogen contents on plant, three-year-old seedlings of two conifer species Picea koraiensis Nakai and Picea meyeri Rehd.

The purpose of this experiment was to search optimal substrate that adapt to cuttings rootage of Cestrum nocturnurm with excellent perfomance and lower cost.

0×10-4 to soak cuttings of Cupressus magcroglossus Gloderest with 4 hours,in the mixed media(1/2pearlite+1/2peat earth),the cottage rooting rate of Cupressus magcroglossus Gloderest was 60.
