Method / resource Three methods of assessing pollen viability agreed poorly.
Observation Saladette had the least reduction in in vitro pollen germination.
Intervention effect Saladette had the greatest loss of seed set when high temperature pollen was used.
Method / resource The authors judged seed set the most reliable measure of gamete viability.
