Pollination of Citrus Hybrids
Stephen H. Futch and Larry K. Jackson
Many of the popular citrus hybrid cultivars developed and released during the last few decades have problems of sexual self-incompatibility which may result in low yields. In the normal flowering process, pollen is deposited from the stamens onto the stigma of an open flower. This is usually done by visiting insects, most often bees, in search of nectar. Since the stamens are adjacent to the stigma, self-pollination is what most often occurs naturally. Even when pollen comes from nearby trees in solid blocks, self-pollination occurs since the varieties are the same.
