Determination of organic acid content in fruits and vegetables
Organic acids are found in a wide range of plant organs and play an important role in metabolism. The content of organic acids varies in different parts of the
Determination of hydrogen peroxide content
Many biotic and abiotic adversities induce the production of hydrogen peroxide (H2O2), and h2o2 plays an important role as a signaling molecule in plant stress
Determination of starch content in cereals
