Abstract: | Corn leaves homogenates were found to release bound (nonextractable) 14C residues from the aerial portion of matured corn plants. The 22,000 g pellet and 10,000 g supernatant fractions were the most active in releasing the bound 14C residues. The released 14C residues comprised mainly 2-OH analogues of the -monodealkylated analogues of atrazine. It is suggested that the enzymatic system in plants may cause metabolic conversion of bound residues. |
