The Alfalfa stigma is a vital part of the female reproductive system in flowering plants, including alfalfa (Medicago sativa). It is located at the top of the pistil, the female reproductive organ of the flower. The stigma is often sticky or feathery in texture, and its main function is to capture pollen grains during pollination.

In alfalfa, the stigma is typically found at the top of the style, which is the slender tube connecting the stigma to the ovary. When a pollinator, such as a bee or butterfly, visits an alfalfa flower, pollen grains from the anthers, the male reproductive organs, may adhere to the stigma.

Once pollen grains land on the stigma, they can germinate and grow pollen tubes, which allow the pollen to travel down the style and fertilize the ovules located in the ovary.

Overall, the stigma of alfalfa plays a crucial role in facilitating the pollination process and ultimately in the production of seeds, which are essential for the plant’s reproduction and survival.
