What Trees Can Pear Trees Be Grafted With
Fruit tree grafting is an important technique to enhance planting benefits, with pear trees being highly regarded as superior rootstocks. This article will delve into the range of trees that can be grafted onto pear trees, with a special focus on the feasibility of grafting with apple trees and peach trees, providing scientific references for fruit farmers.
Suitable Variety Selection for Grafting on Pear Trees
Key Points of Apple Tree Grafting Techniques
Pear trees and apple trees both belong to the Rosaceae family and have good compatibility. When grafting, it is necessary to note: ① Choose 1-2 year-old vigorous scions ② Use the cleft grafting or bud grafting methods ③ The best time is before the spring germination. Successful cases show that using pear trees as rootstocks for grafting apple varieties can achieve early and abundant yields, with fruit sugar content increasing by about 15%.
Other Fruit Tree Varieties That Can Be Grafted
In addition to apple trees, pear trees can also be grafted with: 1. Banana pears: Rare varieties cultivated through special grafting techniques 2. Sand pear varieties: Maintaining the stress resistance advantage of the rootstock 3. European pears: An important way to improve local varieties.
Biological Limitations of Peach Tree Grafting
Although both belong to the Rosaceae family, there are significant differences between pear trees (Pyrus) and peach trees (Prunus): • The cell division cycle of the cambium layer differs by 20 days • The diameter of the nutrient transport ducts does not match (pear trees 2.8mm vs peach trees 1.5mm) • Different expressions of cold resistance genes lead to difficulties in overwintering.
Experimental data show that the survival rate of pear-peach graft combinations is less than 5%, and even if they survive, it is difficult to form effective yields. It is recommended to use closely related species such as plum trees as peach tree rootstocks.
Mastering scientific grafting principles is crucial: prioritize choosing varieties from the same family and genus, and pay attention to the physiological compatibility between the rootstock and scion. It is recommended that fruit farmers use the T-bud grafting method in spring, and after grafting, manage binding and removal of suckers to significantly increase the survival rate of pear tree grafts to over 85%.
