Fruit set temp factors for pepper/tomatoes

Posted by noisebeam 9 (My Page) on

I've experienced and read that peppers and tomatoes don't set fruit when the temps are high.

I've read 95F daytime, I've read >80F night time and other guidelines.

I'd like to learn/understand more exactly how temp affects fruit set to help maximize when at the fringes.

While every variety (and plant due to health/watering/etc) is different, is there any researched backed info on what the impact of temp and specifics on temperature is on fruit set for peppers?

For example perhaps >95F for short period of time is OK, or getting below 80F at night for short period helps, etc. Maybe humidity is a factor?

I do not know of any info that is that specific, although it may be out there.
On a practical note, I plant tomatoes and peppers in fall, protect them from frost, and get lots in the spring.

It is true tomatoes do not set fruit in <90 degrees because the pollen becomes sticky. You can help set fruit by gently shaking the plant/stem early in the morning.
It works. LOL
