Soil temps play an important role also with disease tolerance/resistance
Alright, but that is an external factor, isn't it?


This SAR is put forward as an INTERNAL property or capacity of the
plant. So unless you are saying that a diseased plant develops a fever,
so to speak, I don't see how soil temperature is relevant.


I still haven't seen any answer to what I asked.


Maybe it's too much to expect anyone who has done original work on
this to turn up at Tomatoville but that sure would be nice.


Incidentally, which diseases or blights were you observing?
