Ubiquitin/proteasome pathway and it s role in high plant sexual reproduction;

Polyamines are a group of physiologically active substances in plants and their metabolic changes have a close relation to flower bud formation and development in high plants.

Preliminary high plant database information system of Shanxi have been established.

Mechanism and effect of different contour hedgerow types on runoff and sediment erosion in Three Gorges Reservoir Area;

Adopting contour hedgerow intercropping to control soil erosion in sloping croplands has an important impact on soil and water conservation.

Contour hedgerow intercropping as a type of agroforestry system,in which double-row hedges are planted along contour line in slopelands spaced 4-8 m,has been promoted for erosion control,soil fertility amelioration,and soil water storage in tropical mountain areas.

Macrophyte-Phytoplankton Relationship and Lake Trophic Status;

Effects of Macrophyte on the lake ecosystem as well as its relation to other biology are analysed in many aspects,and the optimum biomass of macrophyte in the lake ecosystem is discussed from cover rate,community structure and distribution proportion of plants.
