Botanical Identification
Reproduction
The reproduction of Eriobotrya japonica is characterized by the production of fruits that possess a distinct texture, categorized as both dry and fleshy in nature. Within these fruits, the seeds play a central role in the plant's life cycle, exhibiting highly consistent physical dimensions. Specifically, the seed volume is remarkably uniform, with a recorded minimum, maximum, and mean volume all measured at exactly 1400 mm³. This stability in seed size suggests a standardized reproductive output, where the fleshy fruit serves as the primary vessel for protecting and eventually dispersing these precisely sized seeds.

- fleshy
- Seed volume max:
- 1400 mm³
