An in vitro system was used for ectomycorrhizal synthesis of Cenococcum geophilum Fr. with Cathaya argyrophylla Chun et Kuang, an endangered species. Calli initiated from stem segments and adventitious roots differentiated from young seedlings were removed and cocultured with Cenococcum geophllum on a modified Murashlge-Skoog medium. Fungal hyphae were visible within intercellular spaces of the callus 4 weeks after inoculation, but definite and well-developed Hartig net structures did not form in the calU 8 weeks after inoculation. The typical ectomycorrhizal structures （i.e. hyphal mantle and Intracortical Hartig net） were observed in root segments 8 weeks after inoculation. This is the first report of aseptic ectomycorrhlzal-like formation/infection between root organ/callus of Cathaya argyrophylla and the ectomycorrhizal fungus Cenococcum geophflum. This culture system is useful for further investigation of mycorrhizal synthesis in Cathaya trees.

The structures of Nylon-1010 with different draw ratios have been investigated by using Small-Angle X-ray Scattering(SAXS).It is shown that by using a simple geometrical construction the following structure parameters can be directly derived from the correlation function,the long period(L),the thickness of the crystal amorphous interphase(dtr),the lamellar thickness(do),the“invariant”(Q),the specific inner surface(Os), and the electron density difference between the core of the crystallites and the amorphous matrix(η_ε-η_ω)。
