Would this work as a test of the theory that the first germination sends
some sort of signal to the other seeds?

Set up three pots for seedling culture. In one pot, plant one just-ripened
seed and several overripened (dried) seeds. In another pot, plant only
overripened seeds; and then in the third pot, plant all just-ripe seeds.
Watch what happens.

If germination triggers more germination, then the seeds in the first pot
should start faster than the seeds in the second pot. Seeds in the third
pot would be a control.
