nuts. Tropical fruits and nuts Citrus Many citrus cultivars are seedless and are produced parthenocarpically without pollination. Some cultivars may be capable of producing fruit either way, having seeds in the segments, if pollinated, and no seeds if not. Citrus that requires pollination may be self-compatible, thus pollen must be moved only a short distance from the anther to the stigma by a pollinator. Some citrus, such as Meyer Lemons, are popular container plants. When these bloom indoors, they often suffer from blossom drop because no pollinators have access. Hand pollination by a human pollinator is a solution. A few citrus, including some tangelos and tangerines, are self-incompatible, and require cross pollination. Pollinizers must be planned when groves are planted. Managed honeybee hives at bloom time are often used to ensure adequate pollination. Papayas Passion fruit Most edible passion fruit varieties are self fertile. Since each flower is only open for 1–2 days and may not get the chance to be pollinated by insects, fruit set can improved by hand pollinating.
