What is the optimum recommended temperature for daylily seed germination: I see lots of recommendations for 65-70 degrees, but nothing along a scientific nature?

"Minimum, optimum, and maximum temperatures for non-stratified seeds were found to be above 16⚬, 22⚬-25⚬, and below 33⚬ C, respectively.

That's 60.8F, 71.6 to 77, and below 91.4 in Fahrenheit.

From:

Stratified seeds germinated over a wider range.

Thank you so much, I just could not seem to find that for some reason.
