Abstract

Multitracer technique and γ-ray energy spectrum analysis was used to study the effect of Ag+ on the uptake of some tracer metal ions in the somatic embryogenesis of Lycium barbarum L. The results show that in the case of some metal ions the uptake changes are selective, cooperative and interactive in somatic embryogenesis due to Ag+ influence. To 50 mg/l Ag+ concentration, the uptake and the frequency of somatic embryogenesis increases along with increasing concentration. Ag+ could speed up cell differentiation and somatic embryogenesis. Above 50 mg/l Ag+ concentration, Ag+ has a poisonous effect, influences tracer element absorption and inhibit the frequency of somatic embryogenesis.
