is the fertility of a tomato plant permanently affected by consecutive nighttime temps above 70F?

Question

This is sort of a 2nd parter to an earlier question. After reading the A&M website, it expressed the likelihood that a plant would remain fruitless if nighttime temps were not low enough, or if a 8-10 hour per day amount of sunlight could not be maintained. In Texas, the sunlight and daily heat requirements are not a problem at all, but the nightime temp is easilly into the 75-80+ range sometimes. If one had a temperature controlled room that could maintain a 70F range (these are potted plants by the way, i.e. mobile) could this allow the plant the ability to fruit again, or is it game over after too many nights of the wrong temp?

Answer 1

A lot would depend on variety of the tomatoe. It gets downn to 55 or 60 regularly here at night. My tomatoes don't seem to have a poblem. If they are in pots you may have to shake the stems of the plant each day in order to help them polinate. Insects usually do this for you but I give mine a shake anyway just to be sure.

Answer 2

Honestly, I've never had a single problem with it. It gets that hot at night where I live all the time and my tomatoes grow VERY well.
