Kigelia Africana

Kigelia Africana

Why are the seeds of this species difficult? The seeds present no inherent problems in storage or germination. However, if they have not been properly dried and stored under optimal conditions, storage life and viability will be reduced.

Seed Storage

This species has Orthodox seeds – dry to 15-20% eRH and store at -20ºC, or as cool as possible.

Germination Requirements

Extract the seeds from the fruits and dry in the shade for a day before selecting the seeds. Germinate on agar, germination paper or sand at 25ºC.

The seeds of this species do not display dormancy (inferred from available information on germination and of characteristics of seeds in this family).

Seed Morphology

The indehiscent fruit (15-25 x 30-90 cm) looks like a large sausage. The fruits become grey at maturity.
