Do Zucchini HAVE to be pollinated early in the morning?

It was my understanding that the reason to hand pollinate zucchini in the morning is because the flowers close by mid morning. Around where I live, these flowers stay open til about 10 in to morning. Weirdly though, I'll pollinate the zucchini at that around 10 and the zucchini will be aborted. But if I do them at around 6, they grow into full sized zucchini. Is there something I am missing? I thought the only reason why we do hand pollinate early is because the flowers are open.

As the day warms and the humidity rises the pollen becomes tacky and non-viable. it is most viable within a short time after the blooms open.

Plus you have to beat the bugs to it. :)

Maybe they aren't a morning sex type of Zucchini! ;)
Personally, I let my Zuk do their own thing and usually end up putting them on the neighbor's porches on Aug 8th "put a zucchini on your neighbor's porch and run" day!

Lol funny one nancy :)

Thank you digdirt, that's probably exactly what it is. See, I like in Texas so I imagine to heat cause the pollen to be non-useable if I pollinate at 10

Is there some reason you are hand pollinating zucchini?

There can be many reasons for hand-pollinating them. Growing them under cover to prevent SVB is the most common. Stress, lack of active insect pollination, blossom-drop or BER, ratio of M:F blooms, preventing cross-pollination, room for only 1 or 2 plants, etc. are all reasons for hand-pollinating. There is a FAQ here about it.

It is good to get some started as soon as possible....before the plants die!

I suspected it might be the SVB, but I didn't realize they were a problem for Zucchini as well as other squashes. I haven't grown much squash. Thanks Dave, for that explanation.

I have a sinking feeling I'm going to be hand-pollinating this year since it seems that most everyone's hives in and around Central Ohio got wiped out this past fall/winter from Colony Colapse :^( so that's good to know about doing it early in the mornings. I imagine the same thing would apply to cucumbers? What about bush green beans, or are they self-pollinating?
