Organic acids does not increase the salinity of the soil & nickel stress in plants.

Thank you for answering, but i meant the opposite ,how do salinity and nickel stress affect organic acid content in plants?

In salt stress condition organic acid decreased in plants. I can give you an example. In alfalfa, plants were subjected to 0.15 m NaCl stress for 2 weeks, total organic acid concentration in nodules and roots were depressed by more than 40%.

thanx a lot for your help

increase in salinity and any type of stress adversely affect metabolic activities of plant so amount of organic acids will also be affected

Thanx a lot
