What are the plants with green leaves in summer and bare stems in winter?

Deciduous plants are commonly used terms in botany. Compared with evergreen plants, there will be a time in a year when the leaves will fall off completely and the branches will become bare and leafless. The reasons for falling leaves, such as season and climate, are obviously related. Because the temperature in autumn and winter is generally low and the climate is dry, it is easy to lack water, the plant growth stops, all the leaves fall off, and the tender leaves grow again in the next year. All plants are deciduous or semi-deciduous, except most species that grow in tropical and temperate regions are evergreen. Semi-defoliation means that plants are also affected by autumn and winter climate, resulting in slow growth and some leaves falling off. Generally, there are many deciduous plants in angiosperms, but only deciduous plants in conifers are Taxodium, Larix gmelinii, Metasequoia glyptostroboides and Metasequoia glyptostroboides. Ginkgo biloba is also a deciduous tree.

Deciduous trees, trees whose leaves all fall off in autumn and winter or dry season every year, generally refer to temperate deciduous trees, such as hawthorn, pear, apple, phoenix tree and so on. Deciduous leaves are an adaptation of plants to reduce transpiration and survive in cold or dry seasons. This habit is formed in the long-term evolution of plants. The reason of defoliation is that the sunshine is short, the internal auxin decreases and abscisic acid increases, which leads to delamination.
