FW: Pollination - time of day criticality?

From a botanical perspective many flowers ripen pollen at an earlier time than they are receptive.  This prevents self fertilization.

Are there other significant factors, related to the pollen or the stigma

One rough idea is that when the flower is producing pollen it is not
receptive to it. Sometimes you can see changes in the flower which
indicate when it is receptive.

I see to recall Ian Young (SRGC Bulblog) discussing when the best time
for pollinating various bulb flowers is.
