Abstract
Tracer silver applied as a negatively charged silver thiosulphate complex moved freely in gerbera stem while AgNO3 made negligible movement.
The movement of 110mAg with 3NaEDTA and with 8-HQC plus sucrose was much slower than that of tracer silver with sodium thiosulphate.
Determination of radioactivity in dissected gerbera parts revealed the greatest amount of 110mAg in the receptacle tissue when inflorescences were kept in the silver thiosulphate solution.
The results obtained after uptake of silver nitrate with NaEDTA solution and silver nitrate with 8-HQC plus sucrose solution showed that the most radioactivity appeared in the stem base and in the upper parts of ray florets.
Treatment with silver nitrate plus NaEDTA solution prolonged gerbera vase-life and counteracted the ethephon effect.
