The seedlings of 2-year-old Chimonanthus praecox seedlings could also be used as rootstocks and grafted 3-4 cm away from the ground by the method of bagging and moistening the tender branches. The survival of Chimonanthus praecox seedlings could be judged after 7 to 10 days;
The "Purple Butterfly" and "Jade Butterfly" of Rhododendron fortunei were used as Rootstocks to breed Belgian or Western Rhododendron;
Cherry seedlings were used as Rootstocks to bud propagate the excellent varieties of cherry;
The seedlings of Malus hupehensis, Malus hupehensis, Malus penduliformis and Malus crabapple flowers were used as Rootstocks to carry out T-shaped budding to propagate Begonia of excellent varieties;
Acer palmatum seedlings were used as Rootstocks to propagate Acer rubrum and Acer plumage seedlings by bagging grafting.
