Non-parthenocarpic plant

Caption:
Musa acuminata is one of the few wild species of banana to have plants that are parthenocarpic, i.e. have to ability to produce a fleshy fruit in the absence of pollination. This particular Musa acuminata plant is not parthenocarpic, as seen by the difference between the fleshy and seedy fruits on the left and the scrawny fruits on the right. The latter have either not been pollinated or only a few of the ovules have been pollinated (the bulges which indicate that an ovule has been pollinated and developed into a seed that stimulated pulp production). Had the plant been parthenocarpic, the non-pollinated fruits would have filled up with pulp except that, unlike the pollinated fruits, they would have had no or few seeds.
