I had hypothesized an interaction between nicking and soaking. There is one, but not what I expected. I thought that the nicked seeds that we soaked would do the best, but I was wrong. The best germination was for the nicked seeds that were planted dry. Soaking actually has hurt our germination rate. How weird!
Here's my data. (I love data.)
I'll collect data each month. What I want to know is whether the important outcome is in terms of how quickly the seeds germinate or how many germinate. Maybe the other conditions will catch up over time and it will turn out that the effect of nicking and soaking means nothing in the end. We shall see. Whatever the results, there's enough going on to justify a presentation at a conference. That will be a great resume-builder for the Peruvian college students I'm working with.
