Can mustard and radish bolt from low temperature?

I'm a bit mystified. Does this makes sense, or could be from the big difference in low night temp and higher day time temp of Ohio? Does direct sunlight play a bigger factor than ambient temp?

I used to grow mustard and radish in Florida, all the way past May, even with some days it reaches over 90*F the plants won't bolt. Here in Ohio, the night temps are 60*F and 80*F during the days and even with shades they bolted very early. I also planted some at my sister house which have extra shade behind trees and they bolted too.

In any case, I sowed some more mustard in the hottest part of the garden to see what'll happen.
