The mobility of different ionic forms of silver ((110m)Ag) has been studied using semiconductor radiation detectors. Silver, applied as silvernitrate (2mM), moves upward in the stems of cut carnations (Dianthus caryophyllus L.) at about 3 cm day(-1). This transport has the characteristics of a chromatographic exchange transport, but is not promoted by the addition of other cations (K(+) or Ca(2+)). The silverthiosulphate anionic complex is transported at the same speed as [(32)P]phosphate (about 2 m h(-1)); orders of magnitude faster than Ag(+). The antiethylene action of silver is preserved in this complex, as shown by a significant improvement of the longevity of carnation flowers in the presence or absence of ethephon, even after a short treatment with the silverthiosulphate complex. Analysis of the silver content of different flower parts after a silverthiosulphate treatment shows a distinct accumulation in the receptacle, possibly associated with the antiethylene action.
使用半导体辐射探测器研究了不同银离子形态（(110m)Ag）的迁移性。将硝酸银（2mM）作为银源施加于康乃馨（Dianthus caryophyllus L.）的茎段中，银以约 3cm·天(-1)的速度向上迁移。这种迁移具有色谱交换运输的特征，但不被添加的其他阳离子（K(+)或 Ca(2+)）所促进。银硫代硫酸盐阴离子络合物的迁移速度与 [(32)P]磷酸盐（约 2m·h(-1)）相同；比 Ag(+)快几个数量级。正如在乙烯作用抑制剂乙二膦酸存在或不存在的情况下，银硫代硫酸盐络合物处理后短时间内康乃馨花的寿命显著延长所表明的，这种络合物保留了银的抗乙烯作用。银硫代硫酸盐处理后对不同花朵部位的银含量分析表明，在花托中存在明显的积累，这可能与抗乙烯作用有关。
