Question

In Calotropis, how is herkogamy achieved?

पर्याय

• Anthers dehisce at a distance from the stigma

• The anthers are positioned higher than the stigma

• The pentangular stigma (pollinium) is positioned above the level of the anthers

• The style is much longer than the stamens

Answer 1

In Calotropis, herkogamy is achieved through positional separation where the pentangular stigma is positioned above the anthers. This vertical separation prevents self-pollen from reaching the stigma without a pollinator's intervention.
