Abstract
The effect of retardant Prohexadione-Ca (BAS 125 10W, BASF Corp., Germany) and heavy metal copper on growth and endogenous concentrations of free and conjugated putrescine, spermidine and spermine in roots and leaves of pea plants were investigated. It was found that the polyamine concentrations increased seven days after the treatments. Most considerable increase of polyamines was detected in plants treated with copper and Prohexadione-Ca. The variations in polyamine concentrations in leaves and roots of pea plants suggest that Prohexadione-Ca had a protective effect against Cu stress of pea plants, which was expressed by additional accumulation of polyamines.
