Seed assay by triphenyltetrazolium chloride (TTC) method
Viable seed embryos undergo continuous redox reactions during respiration, and the hydrogen shed reduces the coenzymes (NAD or NADP). When TTC penetrates into t
Determination of coolant content in plant tissues
Phenolic substances in plant tissues are oxidized to Da by polyphenol oxidase, and Da can automatically polymerize into colorful substances and browning occurs.
Measurement of vitamin C content
