Modification des teneurs en ATP, glucose, fructose et saccharose dans des plantules de concombre (Cucumis sativus) sous l'action de divers herbicides

Abstract: Résumé: L'application durant 3 jours de doses létales d'atrazine, de MCPA, de dichlobénil, d'alachlore et de paraquat par voie racinaire et/ou par voie foliaire a permis de démontrer que la phytotoxicité des herbicides n'est pas nécessairement liée à une diminution d'ATP. L'atrazine administrée par voie racinaire provoque dans les feuilles une diminution de 57–88% de glucose et de fructose; de 70–97% de saccharose. Dans les ratines les pertes sont respectivement de 14–60% et 33–96%. L'atrazine par voie foliair… Show more

“…At its simplest, this could involve membrane denaturation or even cell death. Alternatively it could involve a blockage of cell metabolism such that the ATP supply was diminished (Gruenhag & Moreland, 1971; Decleire & Decat, 1981; Peixoto et al ., 2003), precluding the active transport or synthesis of solutes. However, the osmotic pressure gradient between the cell sap and the culture medium was maintained even after 48 h in the presence of 480 n m OAC.…”
