- Intervention effect Pollen storage had no significant effect on final fruit weight.
- Recommendation Low-temperature storage represents the most effective strategy for preserving date palm pollen functionality.
- Recommendation Refrigerated storage around 4 °C appears a reliable and accessible option for short- to medium-term pollen preservation.
- Recommendation Freezing conditions may be advantageous for longer pollen storage periods when moisture control and thawing are properly managed.
