Phytoremediation of Sr~(2+ and its influence on the growht,Ca~(2+) and solasodine content of shoot cultures of Solanum laciniatum

摘要

Shoot cultures of Solanum laciniatum were able to remediate Sr~(2+) containedint hemedia(25-200 mg l~(-1) and to accumulate Sr~(2+) up to 0.13% in the biomass.The growth of these shoot cultures remained good.Sr`(2+) at 50 and 100 mg l~(-1) caused thevascular system of the stem to develop outwards with an increase of solasodine content 1.6 and 1.4 fold,respectively.A decrease ofCa~(2+) content of 16% was observed at Sr~(2+) 100 and 200 mg l~(-1).
