graft hybridization
2.Abstract：Emphatically discusses the relationship between graft hybridization and the specificity of heredity in fruit trees on the basis of introducing the recent achievements in plant graft hybridization.
3.Abstract:The paper considers that the experiment of affect scion of Prunus japonica Thunb on stock of Prunus armeniaca L. furnish fresh evidence for graft hybridization，and proposes the possible mechnism for production of tillering Prunus japoniaca Thunb according to recent achievements in plant molecular biology.
4.The preparation of functionalized mesoporous molecular sieves were introduced, which are including the formation of the acid active sites, redox active sites and used the support for immsobilizing enzyme catalysts by heteroatomic substitution; the formation of polymerization active sites, acid active sites or chiral catalysis sites by the organic-inorganic graft (or hybridization); as the carriers, the transition metals, transition metal oxides and acid catalysts are supported.
