What are the morphological characteristics of the large-leaf seedless jujube?

The large-leaf seedless jujube tree has a disordered-head canopy, strong trunk dominance, and sparse branch nodes. The leaves are large, broadly ovate, and dark green. The fruit is large and elliptical, uneven in size, with the vertical diameter greater than the horizontal diameter. The single fruit weighs 15 grams, and the largest single fruit weighs about 25 grams. The peel is relatively thick and light red. The flesh is pale white, crisp in texture, juicy, and sweet-and-sour. The stone degenerates into a layer of papery membrane and can be eaten together with the flesh. It is a fine variety for fresh eating. The plant has poor adaptability and resistance to pests and diseases, and is prone to variation when planted in different regions.
