Title

Dragon Fruit ( Hylocereus undatus ) Pollination in New Zealand: A Preliminary Report on Flower Visitors, Natural Pollen Deposition, and Artificial Pollination

Max N. Buxton; Laura Mesa; Melissa A. Broussard New Zealand Journal of Crop and Horticultural Science 2026. doi:10.1002/nzc2.70053

Other claims from this paper (9)

Observation Copious amounts of pollen were recorded on the stigma.
Observation Little pollen germination was observed on the stigma.
Observation Stigma receptivity was highest at flower opening and gradually declined over time.
Observation Pollen could be efficiently collected with a commercially available, handheld keyboard vacuum.
Intervention effect Pollen collected within 12 h of anthesis had the highest viability.
Intervention effect Desiccating pollen for 30 min over silica gel or 12 h in a drying cabinet had no apparent negative effect on pollen viability.
Intervention effect Longer desiccation periods had a negative effect on pollen viability.
Intervention effect Desiccated pollen stored at −20°C for 10 months had pollen viability similar to freshly collected pollen.
Recommendation Manual pollination of dragon fruit is suggested to be required in New Zealand to overcome pollen deficits.
