The Translocation of Pulsed Radioactive Silver Thiosulphate Within Cut Carnation Flowers

Abstract

The movement of silver thiosulphate (STS) within cut carnation flowers was monitored on a time-course basis. After a ten minute STS (^110mAg) pulse, the ^110mAg moved rapidly into all the flower parts. With time, however, the ^110mAg steadily accumulated within the receptacle. Nine days after application the radioactive silver was no longer detected in the petals and ovary. Petal applied radioactive silver nitrate showed that silver can become phloem-mobile. This silver also accumulated in the receptacle.
