Title Slide 

Bee release

Bees may move between flowers on the same plant.

Hypothesis:

Growers can delay the start of bloom.

Growers can control the timing of bee emergence.

Tested hypothesis with:

Hand pollinations

Manipulating standing crop

Flower standing crop treatments

Bee movement treatments

Results: Standing crop.

Photo: Plants in greenhouse.

Results: Racemes per plant.

Results: Flowers per raceme.

Results: Pods per bract

Results: Seeds per pod

Summary

Do bees move within plants?

Methods

Results: movement. between plants

Results: Flowers per raceme

Flowers per raceme, high standing crop

Results: More flowers per raceme early season.

Marked racemes

Seeds per pollination in succession on the same plant
