The installation methods of wax sealed test blocks while carrying out concrete seepage resistant test are introduced from the principles, operation methods, materials, tools, equipments, safe measures and so on.

A scion-producing nursery for 120 plus trees of Carya cathayensi was established by grafting the plus tree scions on Platycarya strobilacea stocks,and the survival rate,growth indices and the shoot numbers from the scions were investigated according to the diameter of the stocks one year later.

Effects of temperature and humidity on water loss and germination of Chinese date scions in storage;

Effect of Different Scions/Rootstocks on Quality of Cucumber Fruits in Greenhouse;

Studies on the difference of radial growth between scion and stock in the graft union in Hevea brasiliensis;

As was shown in the data determined one year later,root length,root surface area,and root volume and biomass of the gratfed plants with different cions of pecan displayed significant differences.

The results of the research on grafting reproduction, which takes Celtis julianae Aurescens and Celtis julianae as cion and stock, indicate that the difference of thickness of cion, age of stock, period of graft, method of graft, and measure of maintaining humidity exerts influences on survival probability to different degrees.
