| Abstract: |
| Grafting comparative experiments were carried out by different grafting time，stocks，scion
segments，grafting techniques and cultivation methods，using Cerasus campanulata，C. speciosa，C. campanulata
‘Double-flowered’ as stocks and C. yunnanensis‘ Guangzhou’ as scion. Results showed that the best grafting time
of C. yunnanensis‘ Guangzhou’ was January in Guangdong Province，the survival rate after 60 days was 91.67%，
one year later the height of trees was 143.34 cm. The good choice of breeding C. yunnanensis‘ Guangzhou’ was using
the 1-year-old seedlings of C. campanulata and C. campanulata‘ Double-flowered’ as stock，the survival rates
respectively was 94.58% and 93.75%，and the heights of trees were 151.54 cm and 152.27 cm. Different parts of
scion had a little effect on the survival rate and height，while the terminal buds and adjacent two sections had better
effect，the survival rate was 92.92% and the height was 152.54 cm. Cut-grafting was the best choice among different
grafting techniques，the survival rate reached 92.08%，and the height of trees can be up to 154.13 cm. The method with trees planted in land and covered with agricultural films was the best，the survival rate was 95.42% and the
height was 169.63 cm. |
