Leslie, I wanted to thank you for writing this article. The main take-away that I got from it that I didn't know before was the temperature at which pollen becomes viable and the temperature at which the pistils shut down. I didn't realize the pollen and stamen juices were quite so touchy, I thought my pollinations weren't taking simply because they were too thirsty. (It might still have been that, too, but atleast now I know to pay more attention to the temperature as well.)
