Abstract
The abscisic acid (ABA) content of the root tips of four crops grown in lanthanide chloride solution and their root lengths had been determined. At lanthanide concentrations of 5 and 10 ppm, these crops all grew well and the ABA decreased. At higher lanthanide concentrations (100–500 ppm), the ABA is increased again. At these concentrations of lanthanum chloride, the photosystems I and II (PSI and PSII) and whole electron chain transport activities were inhibited. PSII was more sensitive than PSI, and it is concluded that La3+ acts on the diphenylcarbazide (DPC) action place of PSII oxidizing site.
