Title

Other claims from this paper (7)
- Observation The model restricts quantity limitation to the lowest pollen-receipt range, where siring success per grain is high.
- Observation The model finds quality limitation across the pollen-receipt range when imported pollen is below the highest quality.
- Mechanism All post-pollination aspects of seed production govern quantity limitation along with pollinator availability and efficiency.
- Method / resource The standard pollen-supplementation technique does not estimate total pollen limitation.
- Method / resource The standard pollen-supplementation technique does not separate pollen quantity and quality limitation.
- Method / resource The proposed protocol estimates total pollen limitation and its quantity and quality components.
- Observation Quantity limitation probably occurs much less often than pollen-supplementation experiments imply.
