Abstract

Harrisia eriophora is a succulent, candelabriform tree endemic to Cuba. Its fruits are cactidia that produce between 500 and 1,500 seeds. The seeds measure 2.62 ± 0.30 mm in length, 1.50 ± 0.09 mm in width, and 0.95 ± 0.05 mm in thickness, with a moisture content of 13.54 ± 3.4 %, and possess a bent peripheral embryo. Within the same seed batch, photoblastic seeds with physiological dormancy and non-dormant seeds coexist, showing an optimal thermal range of 25/30 °C and a positive response to chemical scarification. The seeds can be stored at room temperature for up to two years without losing viability.
