PVP is an additive in plant tissue culture used to neutralize and bind polyphenols and alkaloids released by explants. By forming hydrogen bonds with phenolic substances, PVP inhibits their oxidation into toxic quinones, which would otherwise lead to tissue browning and necrosis.
As a specialized alternative to activated charcoal, PVP offers the advantage of not non-specifically adsorbing plant growth regulators (hormones), ensuring the medium’s composition remains precise and stable. Additionally, the medium remains clear, allowing for easier visual monitoring of culture development and potential contamination.
Tested in plant tissue culture.
