re: pollen viability

gunnar - your comments about tomato pollen made me wonder if the heat and
humidity that we have when i am trying to make crosses is causing a problem.
 in the world of iris, it says most common failures are from immature or
nonviable pollen, unreceptive stigmas, or 'unfavorable weather'.  

everybody - does anybody know what the book means by unfavorable weather?

also, it says the stigma is most receptive 3 or 4 hrs after blossom
'opening'.  what does that mean?  after it is fully expanded? or after it
first starts trying to unfold?  i bet i am waiting too long.
