Abstract:

Geocarpy and amphicarpy are two special types of fruiting modes in angiosperms, and they occur mostly in terrestrial herbaceous plants. Geocarpous and amphicarpous species often occur in unstable habitats, where water or light is limiting, soil disturbance is frequent and environmental fluctuations are high. These two types of fruiting modes are important plant ecological adaptations that evolved via natural selection. The adaptive advantages of geocarpy include high survivorship of offspring in the favorab...
