HPLC and in vivo Spectrophotometric Detection of Porphyrins in Plant Tissues Treated with Porphyrinogenic Herbicides


Protoporphyrinogen oxidase (Protox) inhibitors and other com pounds which block o r stim­ ulate the porphyrin pathway can cause sufficient levels o f porphyrins to accum ulate in plant tissues for severe photodynam ic dam age to occur. The gross sym ptom ology for all o f these p o r­ phyrinogenic herbicides is similar. Porphyrin accum ulation induced by… (More)
