Botanical Identification

Life history

The life history of Anonidium mannii is characterized by its status as a perennial species, allowing it to persist in its natural habitat over multiple growing seasons. As a long-lived woody plant, it establishes a stable presence within its ecosystem, undergoing various developmental stages that contribute to its longevity and reproductive success. This perennial nature ensures that the plant can withstand environmental fluctuations, maintaining its biological functions and structural integrity over a continuous lifecycle rather than completing its development within a single year.

Lifecycle :

perennial

Morphology

The morphology of Annona mannii is characterized by a woody growth form, specifically classified as a tree. It is a self-supporting plant that does not function as a climber or a liana, nor does it exhibit parasitic or epiphytic behaviors, maintaining an independent and terrestrial existence. In terms of stature, the plant displays significant vertical development, with its height ranging from a minimum of approximately 6.10 meters to a maximum of 18.29 meters, though it reaches a mean height of 25 meters.

Physiology

The physiology of Annona mannii is characterized by a standard metabolic framework typical of many tropical woody species. It utilizes the C3 photosynthetic pathway, a process in which carbon dioxide is fixed directly into a three-carbon compound during the initial stage of the Calvin cycle, rather than employing the more specialized C4 or CAM mechanisms. Furthermore, this species does not function as a nitrogen fixer, meaning it lacks the symbiotic relationships with nitrogen-fixing bacteria required to convert atmospheric nitrogen into a usable biological form, and must instead rely on the uptake of available nitrogenous compounds from the soil.

Nitrogen fixer :

no

Photosynthetic pathway :

C3

Reproduction

The reproduction of Anonidium mannii is characterized by a specific flowering phenology and the development of specialized fruit and seed structures. The flowering period typically commences in February and concludes in March, although the timing can be variable across different months of the year. Following successful pollination, the plant produces fleshy fruits that house the seeds. These seeds are notable for their consistent and substantial size, maintaining a uniform volume of 4500 mm³, which represents both the minimum and maximum recorded seed volume as well as the mean volume for the species.
