Recently tried to search for some scientific answers about the viability decrease in the range of “normal” enviroments (non cooled/stored) and came across these.
Shared for anyone who is intrested:
and a second one

Those papers sick, great share! For folks interested in testing their own pollen and seed viability you can use what is called the TZ test or tetrazolium test. You can get these reagents on Amazon still, i think, and can be done at home. Just need a microscope or other magnifier to confirm. I used to have to do this with wildflower populations we collected seed from and its a well established test in the science community.
