Overview

Observational reports highlight embryo development and male fertility in Portulacaria pygmaea, indicating potential for cryptic hermaphroditism.

Key Points

  • Rapid fruit development occurred within 24–48 hours on male Portulacaria pygmaea plants, suggesting sex expression flexibility.
  • Seeds formed within fruits exhibited embryo development under controlled conditions, indicating functional male fertility.
  • Controlled pollination confirmed male fertility, with successful fertilization of female flowers, highlighting reproductive system dynamics.
  • Further molecular analyses are needed to understand the factors triggering sexual plasticity in these dioecious plants.
