The introduction ofCornus stolonifera and its propagation techniques

Abstract

Cornus stolonifera is a ornamental tree species which was introdced to China in 1982. During the period of ten-year experiment a complete and systematic study on its botanical features, biological charcteristics, growth rhythm and propagation techniques was carried out on basis of the comparison withthe native speciesCorrns alba. The research results showedthatCornus stolonifera has many advantages overCornus alba in those such as fast growing, cold endurance, drought resistance, easy propagation.disease and pest-resistance, beautiful tree form, bright colour branches, long florescence, persistant fruits and integrate visual effects. Practice has proved that it is reslly a fine species for tree-planting. Not only does it have the function of water conservation, but also its branches can be used as a fine weaving material. Up to the present, about ten thousand plant stocks have been planted by more than 30 units in 11 cities of 6 provinces and it has been well recieved by people.
