Watermelon pollination is essential to the production of fruit. A watermelon plant is a cucurbit and both male and female flowers are located separately in the same plant. In order to set fruit, pollen from the male flowers must make its way to the female flowers.

Lack of pollen during full flowering of seedless watermelon plants will have negative effect on total yield and fruit quality.

Since the pollen in triploid male flowers is not viable and female flowers in triploid plants require viable pollen to set fruit, it follows that there must be separate seeded pollenizer plants available to provide pollen. The choices for today’s growers are harvestable or non-harvestable pollenizers. We recommend Ace, Ace Plus, Wild Card, Wild Card Plus (non-harvestable) and SWD8585 (harvestable).

Triploid watermelon is mainly pollinated by bees and other insects that hop from flower to flower and distribute pollen from seeded pollenizer plants to triploid hybrid plants. Because watermelon flowers open only for a short time, it is essential that bees and pollens are present during pollination. It is also essential that the full-flowering period of the seedless plants (which takes about 3-4 weeks) should match with the full-flowering period of the pollenizer plants, in order to have plenty of pollen available during pollination. Lack of pollen during full flowering of seedless watermelon plants will have negative effect on the total yield and fruit quality. Therefore, early-maturing seedless watermelon hybrids should be combined with early and prolonged-flowering pollenizer plants to get high yield and quality watermelon production in commercial production field.
