What Do Jujube Leaves Look Like? A Detailed Guide to Their Morphology and Growth Characteristics

The leaves of the jujube tree are alternate on the jujube spur, growing on deciduous branches, with short petioles and stipules; in thorny varieties the stipules become spines, but on deciduous branches they remain stipules. Beneath the upper epidermis of the leaf is spongy tissue, and photosynthesis mainly takes place on the upper surface of the leaf, while in the jujube tree both the upper and lower epidermis contain palisade tissue, and both carry out photosynthesis. Leaf drop in the jujube tree is a normal physiological phenomenon, but various adverse factors (such as drought, pests and diseases, damage from beating the jujube harvest, etc.) causing early leaf drop will affect the transformation and accumulation of nutrients and have an adverse effect on flower bud differentiation the following year. In cultivation, leaf retention must be ensured so that the leaves drop after Frost's Descent.
