Bees visit the blossoms freely for nectar and pollen. A copious quantity of nectar may collect in the open cavity around the ovary, below the base of the anthers. There are 10 to 50 small fragrant white flowers in a panicle, only about 12 percent of which develop into fruit. Thinning of fruit may be necessary if the set is too heavy, but usually the set is too light for economic production. The pollination requirements seem to vary with cultivars of loquat, but all are benefited by, and some require, cross-pollination.
High temperatures seem to be detrimental to fruit set.
This could be the result of a decreased period of stigma receptivity or pollen viability associated with inadequate pollinator activity. Nothing is mentioned in the literature about the pollinating agents for loquat. However, honey bees visit the flowers freely and are usually the primary visitors. Presumably, they are satisfactory pollinating agents. Where maximum fruit set is desired, plants should probably be in close proximity and bees should be present in abundance during flowering.
