| Abstract: | The crown canopy formatoin pattern of 5-year-oid jujube trees was studied. Results show that the annual cycle of leaf area growth of the entire tree is closely related to the air temperature surrounding the orchard and the nutrient status of the dwarf shoots. The growth features of leaves and fruit spurs on the dwarf shoots with a different age are also described. |
