Amorphophallus Fruits and Seeds: Development and Diversity
The reproductive cycle of the Amorphophallus plant concludes with the development of distinct fruits and seeds. Once fertilization occurs, the male zone and the appendix fall off. Subsequently, the female part of the spadix transforms into a cluster of berries. This transition represents a significant physical change, as the female section swells or elongates markedly.
The Anatomy of Amorphophallus Berries
The fruits of the Amorphophallus genus are technically berries. These berries exhibit a wide range in size. They appear as small as 0.5 cm or reach dimensions up to 5 cm in certain species. Additionally, each berry typically houses between 1 to 4 seeds.
One of the most striking features involves their vibrant coloration. The skin of the fruit usually ranges from orange to red. While rarer colors like blue or white exist, Indonesian species mostly show red and orange-red hues. Therefore, these bright colors often attract specific dispersers in their natural habitat.
The Unique Structure of Amorphophallus Seeds
The seeds within these berries have specific adaptations for survival. They possess several unique botanical features:
-
-
Shape and Texture: The seeds are ellipsoid in shape. Moreover, they have a smooth, thin outer layer known as the testa.
-
The Embryo: The embryo varies in size from small to large. It often displays a green appearance on the surface.
-
Nutritional Storage: Notably, these seeds lack endosperm. This differs from many other flowering plants that use endosperm for food storage.
