Demonstrates effective differentiation between two plant species using genetic and morphological traits, highlighting their reproductive characteristics.

Key Points

To differentiate between Passiflora edulis and Passiflora cacao using genetic, morphological, and reproductive analyses.
Characterized the trnL intron sequence of both species.
Analyzed morphological traits such as leaf, flower, fruit, and pollen.
Classified reproductive systems based on pollen/ovule ratio and crossability percentages.
P. cacao was found to be more distantly related to P. edulis than other species in the subgenus.
Distinct morphological and genetic groups were observed for each species.
Both species exhibited high crossbreeding rates despite being facultatively autogamous.
