Feb 1, 2004 · In this review, we (1) survey recent discoveries of pollen and stigma functions both before and after they make contact, and (2) address the great diversity in pollen and stigma structures...
Abstract. The stigma plays several roles such as pollen hydration and selection, and pollen tube nutrition. In the Ficus-fig wasp mutualism, stigmata have an additional, almost unknown, function by representing a physical interface for both plant and wasp reproduction.
Jan 1, 2007 · Recent years, studies indicated that stigma closure may increase pollen capture and receipt, improve pollen germination and pollen tube growth, and prevent intra-floral selfing.
Jan 1, 2003 · Stigma morphology. Pear flowers have an ovary made up of five fused carpels with five independent styles, each one leading to one of the ovary locules in an independent way. Each locule contains two ovules. Thus, pollen grains landing on each stigma will fertilize the ovules of its own carpel.

The female part of the flower is called the pistil. The pistil is made up of a sticky organ which is receptive to pollen called the stigma, a rod-shaped middle part called the style, and a swollen base containing eggs called the ovary. Flowers that only have female parts are called pistillate.
