This species most probably has Orthodox seeds (based on other species in the same genus). To avoid a decline in viability, remove seeds from ripe fruits soon after harvest and allow to dry slowly, under ambient conditions, before transferring to a cool dry room. Dry to 15-20% eRH and store at -20ºC, or as cool as possible.
Germinate on agar, germination paper or sand at 15ºC.
The seeds of this species may be Physiologically Dormant (based on other species in the same genus). If germination is low, this type of seed dormancy can be overcome by mimicking the seasonal patterns of the species' native habitat. Use a moist pre-chill or pre-heat treatment (depending on local climatic conditions) or a dry after-ripening treatment, before germinating the seeds on agar, germination paper or sand at their optimum temperature. If this does not work, you can perform delicate surgery to enable the embryo to grow. Excise the tissue near the root tip.
Accepted name: Solanum macrocarpon L.
