The Brief Report on First Discovery of Vessel in Cycads;

The Anatomical Observation about the Cell Layer with Blue-green Algae in the Coralloid Root of Cycads;

Discovered Vessel in Cycads Again;

Comparative Studies on Structural Feature of Vessels of Four Genera of Cycads with Angiosperm;

Stangerioides, the Most Advanced Species of Cycas;

Based on the external and cuticular structures of Pterophyllum leaves from Early Cretaceous Chengzihe Formation of Jixi coal-bearing basin in eastern Heilongjiang,and on the difference of the species from other known taxa mainly in cuticular characters,a new Bennettitalean species is recognized,and named Pterophyllum chengzihense sp.

Plantlets with Multi-shoots of Cycas revoluta Thunb. in Vitro;

An Investigation on Cultivation and Growth of Cycas revoluta;

PCR fingerprintings of cyanobacteria isolated from coralloid roots of Cycads (Cycas revoluta) and their surrounding soil;

DNA diversity analysis on the Cyanobacteria freshly isolated from Cycads based on PCR with different primers;

Studies on Anatomy Structure Characteristics of Some Cycads and Adaptation of Them and Enviroment;

To enhance work of in-situ protection situations and ex-situ protection situation,add individual number and species by the tissue culture and the like other the artificial propagation,come back their original number and establish good population should be the effective way of cycads resources conservation and exploiture.
