I'm getting results finally. Leaf Margin Necrosis is one symptom of cold temperatures. It appears to be linked to roots unable to absorb nutrients at low temperatures. The plants show varying levels of LMN from 100% to none. The Russian varieties are running about 30% healthy plants. The wild species are showing varying levels of damage with a few S. Pennelli lines and one of the S. Lycopersicoides lines looking best. I will try to get pics later today when the light is bright enough to show the contrast.
