Do seeds from different states have different responses to temperature? This is one of the questions I have been testing for the second half of my internship at the garden. In my last post, I talked about how we were scouting populations across a latitudinal gradient. When we got back to the lab, we began an experiment with common milkweed (Asclepias syriaca) seeds collected from those states last year.
What will happen to native plant populations with climate change? My project seeks to answer this question by looking at a subset of native plant species that are commonly found throughout most of the country. We are testing how the germination responses of seeds respond to different length “winters” and incubation temperatures, in order to look at how they might respond to climate change.
