Other claims from this paper (7)
- Observation Male and female bloom of immature pistachio trees completely overlapped.
- Observation Pollen availability became a limiting factor early in the flowering period.
- Intervention effect Supplementary pollination significantly increased pollen flow compared with open-pollination.
- Observation Pollen levels were extremely low under open-pollination.
- Intervention effect Supplementary pollination, electrostatic pollination in particular, significantly increased pollen germination on the stigma compared with open-pollination.
- Intervention effect Supplementary pollination reduced the level of blank nuts compared with open-pollination.
- Recommendation Electrostatic pollination could supplement natural pollination to ensure higher yields with better nut quality.
