Botanical Identification
Ecology
The ecology of Styphnolobium japonicum is characterized by its adaptability to various environments, though it has specific historical associations with human-managed landscapes. In particular, the species has been successfully cultivated in gardens throughout the southern regions of the USSR, where it thrives under managed conditions. This cultivation pattern suggests a preference for temperate climates found in these southern latitudes, where it can integrate into ornamental and horticultural settings. Its ecological presence in these regions highlights its capacity to adjust to localized soil and climatic conditions typical of garden ecosystems in those geographic zones.
- Habitat :
- cultivated in dardens in southern regions of the USSR
Life history
The life history of Styphnolobium japonicum is characterized by its status as a perennial organism, allowing it to persist through multiple growing seasons and establish long-term presence in its ecosystem. As a phanerophyte, its regenerative buds are located high above the ground on woody stems, a structural adaptation that enables it to thrive as a robust tree. This phanerophyte life form ensures that the plant can withstand seasonal environmental shifts, maintaining its structural integrity and reproductive potential over many years.
- Life form :
- phanerophyte
- Lifecycle :
- perennial
Morphology
The morphology of Styphnolobium japonicum is characterized by its robust, woody growth form, functioning as a self-supporting tree. It is a terrestrial species that exists as an independent organism, neither acting as a parasite nor as an epiphyte. The plant displays a significant vertical structure, typically reaching a plant height ranging from a minimum of 10 m to a maximum of 20 m. As a purely terrestrial tree, it does not exhibit aquatic or semiaquatic tendencies, maintaining a stable, self-supporting stature throughout its life cycle.
- Aquatic :
- terrestrial
- Climber :
- self-supporting
- Epiphyte :
- terrestrial
- Growth form :
- tree
- Parasite :
- independent
- Plant height max:
- 20 m
- Plant height min:
- 10 m
- Woodiness :
- woody
Physiology
The physiology of Styphnolobium japonicum is characterized by a C3 photosynthetic pathway, which dictates its carbon fixation mechanisms and metabolic efficiency in varying environmental conditions. This metabolic strategy involves the direct fixation of CO2 via the enzyme RuBisCO, typically favoring temperate climates where moisture and temperature are moderate. Furthermore, the structural integrity and mechanical properties of its vegetative components are supported by a stem specific density (SSD) with a mean value of 702 mg/cm³. This density value reflects the internal cellular composition and lignification of the stem tissues, contributing to the plant's overall structural stability and resource transport capabilities.
- Photosynthetic pathway :
- C3
- Stem specific density (SSD) mean:
- 702 mg/cm³
Reproduction
The reproductive cycle of Styphnolobium japonicum is characterized by a specific seasonal flowering period that typically commences in July and concludes in August. The plant produces fleshy fruits, which facilitate a zoochorous dispersal syndrome, relying on animals to aid in the spreading of its offspring. The seeds produced are relatively uniform in size, with a recorded maximum and mean seed volume of 110 mm³. In terms of weight, the seeds exhibit slight variations, with a minimum mass of 0.1012 g, a mean mass of 0.109639 g, and a maximum mass reaching 0.1356 g.
