Botanical Identification

Ecology

The ecology of Tilia amurensis is characterized by its specific preference for diverse forest environments, thriving primarily within broad-leaf-elm woods located in river valleys as well as within beech woods situated on mountain slopes. This species occupies a distinct altitudinal niche, maintaining an elevational range that begins at 200 m AMSL and extends up to a maximum of 700 m AMSL.

Elevational range max:

700 m AMSL

Elevational range min:

200 m AMSL

Habitat :

broad-leaf-elm woods in river valleys and beech woods on mountain slopes

Life history

The life history of Tilia amurensis is characterized by its status as a perennial organism, ensuring its long-term presence within its ecological niche through multiple growing seasons. As a phanerophyte, the plant maintains its photosynthetic organs and buds elevated above the soil surface on woody branches, a structural adaptation that allows it to thrive in various forest environments. Its seasonal cycle is marked by being deciduous, meaning it undergoes a period of dormancy where it sheds its foliage annually in response to changing environmental conditions, typically to conserve resources during colder months. This combination of a perennial lifecycle, a phanerophyte life form, and deciduousness defines its rhythmic patterns of growth, seasonal transformation, and long-term survival.

Morphology

The morphology of Tilia amurensis is characterized by its robust growth form as a large, woody tree that reaches a maximum height of approximately 30 meters. As a terrestrial species, it thrives in non-aquatic environments and functions as an independent organism, neither acting as a parasite nor an epiphyte. The plant is strictly self-supporting, lacking the climbing or vining habits of lianas, and relies on its sturdy, woody structure to maintain its upright stature.

Physiology

The physiology of Tilia amurensis is characterized by a C3 photosynthetic pathway, which facilitates carbon fixation through the Calvin cycle. Morphologically, the plant features cordate leaf forms with distinctly toothed margins, and it does not possess leaf thorns or leaf spines. Regarding its structural composition, the species exhibits a mean stem specific density (SSD) of 493 mg/cm³.

Reproduction

The reproduction of Tilia amurensis is characterized by a specific seasonal phenology centered around its flowering period. The flowering process is highly concentrated, with the flowering start occurring in July and the flowering end also concluding within the month of July. This narrow window suggests a synchronized reproductive burst, which is essential for its pollination cycle and subsequent seed development.

Flowering time :
