The next question is, if bees do visit a number of flowers, how will seeds per pod change?
To estimate how much seed set is affected we had to emulate bees again with hand pollinations.
We pollinated 20 flowers in succession on a single plant, up to two per raceme, and removed all other buds and flowers from the raceme. We marked the raceme with different colored threads to indicate pollination order. When pods were mature we collected and counted the seeds.
