I need to grow 3-d old seedlings of durum wheat under drought condition and see the effect on cell wall modifiing enzymes at root level. Do you suggest use of PEG (4000 - 6000 or 8000)?
It can be recommended to use PEG with relatively high molecular weight. The use of Mannitol and low molecular weight PEG should be avoided to reduce uptake by the plant and subsequent side-effects
