WebEven PEG of high molecular weight, such as 4000 to 8000 was found to be taken up by plants. PEG was found in shoots and roots. PEG was taken up by maize and bean plants at a relatively slowly rate of 1 mg/g fresh weight per week. However, when roots were damaged or broken, rate was higher. Cotton absorbed less PEG (Lawlor, 1970).
