Detailed Explanation of the Growth Characteristics of Secondary Branches of Jujube Trees

Permanent branches that grow from the secondary buds in the middle and upper parts of extension shoots, with branches growing in a zigzag bending pattern, are the base branches that form fruit-bearing mother branches, also known as fruit-bearing base branches. After such branches stop growing in the current year, no terminal bud is formed at the tip, and they will no longer extend in growth afterward. Their thickening growth is also very slow, and as the branch age increases, they gradually die back and dry up from the tip. Generally, when extension shoots have strong growth vigor, their secondary branches also have strong growth vigor, and the number of growth nodes increases; when extension shoots have weak growth vigor, their secondary branches are also weak and short, generally having 4 to 13 nodes, with a jujube spur borne on each node. Therefore, secondary branches are an important foundation for fruiting in jujube trees and are also the main framework of the tree body.
