Mr. Gill, During the stress conditions the plant adapted and resulted in alteration in the concentration of its constituents. In the context to your question, yes absolutely it will alter the phyto-constituent concentration. Meanwhile you need to look the intermediate and enzyme which is utilizing in both the signalling so that you get a correlation on the basis of the availability of the enzyme or the intermediate that is commonly used in both the signalling.

Hi, Balraj, what do you mean as correlation? Which kind of stress do you mean? Actually, under stress conditions certain cell type may switch to secondary metabllism, with increasing in accumulations of phenolic compounds..

Good luck!

Correlation means with change in one component other changes or not in environmental stress condition...

The answer is yes, in many stress conditions plants starting to accumulate flavonoids and phenolics as response to stress conditions. This accumulation may serve as protection mechanism. You can look here: http://www.ncbi.nlm.nih.gov/pubmed/17373654.

Your answer is yes. Plants in the condition of stress for prevention of damage of free radical oxygen and for continue of life cycle accumulate this composition.

I agree with Mr.Pourghayoumi and Mr.Pasternak, flavonoids and phenolics secrets as response to stress conditions and serve as protection mechanism.

Thanks for answering...but i want to know that if there is increase in one parameter, it is necessary to increase other or decrease..is there is any relation between both parameters

The correlation between polyphenols and flavonoids depends upon nature of stress given to the plant. In some stress conditions it will show positive correlation (increase in polyphenols-increase in flavonoids) while, in some stress conditions it will negative.
