What are the morphological characteristics of this plant?

Populus cathayana has an upright, deciduous growth habit characterized by an elongated trunk, lanceolate leaves with serrated margins, and slender, pendulous catkins. The foliage is typically bright green during the growing season and transitions to yellow in the autumn. Its bark is relatively smooth when young but develops shallow longitudinal fissures as the tree matures. The reproductive structures consist of small, inconspicuous flowers that hang in drooping clusters. These morphological features are consistent with other members of the Salicaceae family.

What is the geographical distribution of this plant?

This plant is native to the central and southern regions of China, specifically distributed across provinces such as Hubei, Hunan, and Sichuan. It typically flourishes in subtropical climates where moisture is abundant throughout the growing season. Within these territories, the species is most frequently found inhabiting riverbanks and moist valleys near flowing water. The specific range is often restricted by its preference for humid, temperate environments that avoid extreme aridity. Localized populations may also occur in isolated mountain ranges where microclimates provide necessary shade and consistent hydration.

Evidence Level: ★☆☆☆☆

How is this plant cultivated?

This plant Populus cathayana is cultivated by planting suckers or seeds in moist, well-drained alluvial soils within temperate to subtropical climates.

Growers typically ensure the saplings receive full sunlight to promote rapid vertical growth and strong stem development. Regular irrigation is essential during the early establishment phase to prevent drought stress in young root systems. Once mature, the trees require minimal supplemental fertilization because they thrive in nutrient-rich riparian zones.

Proper spacing must be maintained during planting to allow for the expansive canopy and spreading root networks characteristic of this species.

What parts of this plant are used medicinally?

This plant Populus cathayana is utilized medicinally through its leaves, roots, and shoots to treat various ailments. The leaves are often prepared as a decoction to reduce inflammation and alleviate respiratory symptoms. Extracts from the roots are frequently applied to manage digestive issues or skin irritations. Additionally, the young shoots provide specific bioactive compounds that support overall metabolic health. Each of these components offers distinct therapeutic properties depending on the preparation method used.

According to a study published by "Physiologia plantarum", the research examined female and male Populus cathayana subjected to four N fertilization levels ranging from 0-200 mg kg-1. The study focused on biomass accumulation, root-to-shoot (R/S) ratios, and leaf economic traits including leaf thickness, leaf mass per area (LMA), and leaf vein density (LVD). Nitrogen fertilization increased biomass and net photosynthetic rate while reducing the R/S ratio in both sexes. Nitrogen resorption efficiency (NRE) decreased under nitrogen enrichment, while phosphorus resorption efficiency (PRE) increased, resulting in NRE:PRE ratios < 1 across fertilization levels. NRE was positively associated with R/S ratio, leaf thickness, LMA, and LVD, but negatively related to total biomass.
