"When doing your crosses, be aware of the temperature. Stomatic fluid starts flowing at about 80 degrees. It's what comes out of the end of the pistil to activate any pollen that is there. After a bit it dries and seals off the end of the stile. Once the tip is sealed it won't accept any more pollen. You need to have your chosen pollen in place before the tip is sealed."
This info is about Daylilies but, I would guess that it would be similar for other plants as well.
