Abstract:
Chinese tuliptree has not inherent root primordia,which make its cut twigs difficult to survive.In order to increase cutting survival rate,systematic tests and studies were undertaken on mother tree age,twig age,cuttage base material,cuttage season,rooting characters,and post management.The cuttage with twigs having the top and buds could reach 91.4% in survival rate in comparison with 80% of the conventional cuttage.Therefore we built a twig nursery.A simple efficient cuttage technique was developed from the twig nursery,cutting to post management.
