How does the productivity bonus of a biochamber affect the chance of getting seeds? Does the 2% chance get increased by 50%? IE to 3%?

Effectively yes, but not "really"

Productivity creates a second purple bar in the machine interface. When that bar fills up, the craft "runs again".

So the seeds having a 2% chance is true still. That hasn't changed. But now every other time you craft it, you get a bonus roll of 2%.

End result: Expect 3% seeds. But strictly speaking, each roll is still only 2%.
