Hi every one
I calculated the CMS for my plants but after increase in severity of drought stress some of my plant species had cms about 200 or 300 percent. Why this state occurred? Is it normal?
Thank you all.
Dear Mohsen Ashrafi
Perhaps you have calculated cell membrane stability as:
CMS = (1 – (EC40°C / EC100°C)) × 100
Sometimes, this equation is not producing correct results, since electrolyte leakage from cells at 100°C is more than that at 40°C, and this difference increases with increasing water deficit. Therefore, I suggest to apply the following altered equation for estimating CMS:
CMS = (EC40°C / EC100°C) × 100

Dear Kazem Ghassemi-Golezani
I used this formula(CMS (%) = [1 − (T1/T2)/1 − (C1/C2)] × 100). For control plants I did not see error but after severity of stress I gave unreasonable result in treatment plants.
Dear Mohsen Ashrafi
The equation is all right. Please check your data and calculations to find out the reason for overestimating the CMS.

Dear Kazem Ghassemi-Golezani
I measured electrical conductivity in two different season (winter and summer) but the results are same. I do not know what is problematic.
Thank you for your cosideration
Best regards
Mohsen Ashrafi Am facing a similar problem. So finally what did you do.
Thanks.
