Olive stigma refers to the receptive part of the female reproductive organ (pistil) in the flower of an olive plant (Olea europaea). The stigma is a critical component of the pistil responsible for receiving pollen during the process of pollination, ultimately leading to fertilization and seed production.
The stigma is typically located at the top of the pistil and is often sticky or feathery in structure, which aids in trapping and holding pollen grains. Its surface is specialized to recognize and interact with compatible pollen, facilitating successful fertilization.
In the case of the olive plant, the stigma is an essential part of the female reproductive system, playing a crucial role in the production of olives and the continuation of the plant’s life cycle through seed formation.
